  • Conflicts or wars in which major powers purposely refrain from employing all their armed strength are often known as limited wars.
  • A rebellion is not legally considered a war; to entitle the armed forces of the rebels to the rights and privileges of belligerents, the government they serve must be organized so as to be in a position to meet the duties resting on belligerents, that is, they must have the power to maintain law and order within the regions occupied by them and to carry on war on a large scale by land, sea, or air. International hostilities sometimes continue for long periods of time without being acknowledged as wars. The Korean War was regarded by the U.S. government as a police action. Conflicts or wars in which major powers purposely refrain from employing all their armed strength are often known as limited wars. International wars are generally terminated by treaty, and civil wars by a peace proclamation. The usages, customs, and treaties of nations have formed a system of laws of war.

      Wow!
  • Commercial logging is the single largest cause of rainforest destruction, both directly and indirectly. Other activities destroying the rainforest, including clearing land for grazing animals and subsistence farming. The simple fact is that people are destroying the Amazon rainforest and the rest of the rainforests of the world because "they can't see the forest for the trees."

  • Two drugs obtained from a rainforest plant known as the Madagascar periwinkle, now extinct in the wild due to deforestation of the Madagascar rainforest, have increased the chances of survival for children with leukemia from 20 percent to 80 percent. Think about it: eight out of ten children are now saved, rather than eight of ten children dying from leukemia. How many children have been spared and how many more will continue to be spared because of this single rainforest plant? What if we had failed to discover this one important plant among millions before human activities had led to its extinction? When our remaining rainforests are gone, the rare plants and animals will be lost forever-and so will the possible cures for diseases like cancer they can provide.
    • Marius S
       
      Because of deforestation, all this has happened!
  • Rainforests have evolved over millions of years to turn into the incredibly complex environments they are today. Rainforests represent a store of living and breathing renewable natural resources that for eons, by virtue of their richness in both animal and plant species, have contributed a wealth of resources for the survival and well-being of humankind. These resources have included basic food supplies, clothing, shelter, fuel, spices, industrial raw materials, and medicine for all those who have lived in the majesty of the forest. However, the inner dynamics of a tropical rainforest is an intricate and fragile system. Everything is so interdependent that upsetting one part can lead to unknown damage or even destruction of the whole. Sadly, it has taken only a century of human intervention to destroy what nature designed to last forever. The scale of human pressures on ecosystems everywhere has increased enormously in the last few decades. Since 1980 the global economy has tripled in size and the world population has increased by 30 percent. Consumption of everything on the planet has risen- at a cost to our ecosystems. In 2001, The World Resources Institute estimated that the demand for rice, wheat, and corn is expected to grow by 40% by 2020, increasing irrigation water demands by 50% or more. They further reported that the demand for wood could double by the year 2050; unfortunately, it is still the tropical forests of the world that supply the bulk of the world's demand for wood.

      rainforest could be gone if the wood suplies keeps going up like this!
  • In 1950, about 15 percent of the Earth's land surface was covered by rainforest. Today, more than half has already gone up in smoke. In fewer than fifty years, more than half of the world's tropical rainforests have fallen victim to fire and the chain saw, and the rate of destruction is still accelerating. Unbelievably, more than 200,000 acres of rainforest are burned every day. That is more than 150 acres lost every minute of every day, and 78 million acres lost every year! More than 20 percent of the Amazon rainforest is already gone, and much more is severely threatened as the destruction continues. It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year. If nothing is done to curb this trend, the entire Amazon could well be gone within fifty years. Massive deforestation brings with it many ugly consequences-air and water pollution, soil erosion, malaria epidemics, the release of carbon dioxide into the atmosphere, the eviction and decimation of indigenous Indian tribes, and the loss of biodiversity through extinction of plants and animals. Fewer rainforests mean less rain, less oxygen for us to breathe, and an increased threat from global warming.

      that is just scary but it is something we must know inorder for someone to solve the problem someday...i guess
  • But who is really to blame? Consider what we industrialized Americans have done to our own homeland. We converted 90 percent of North America's virgin forests into firewood, shingles, furniture, railroad ties, and paper. Other industrialized countries have done no better. Malaysia, Indonesia, Brazil, and other tropical countries with rainforests are often branded as "environmental villains" of the world, mainly because of their reported levels of destruction of their rainforests. But despite the levels of deforestation, up to 60 percent of their territory is still covered by natural tropical forests. In fact, today, much of the pressures on their remaining rainforests comes from servicing the needs and markets for wood products in industrialized countries that have already depleted their own natural resources. Industrial countries would not be buying rainforest hardwoods and timber had we not cut down our own trees long ago, nor would poachers in the Amazon jungle be slaughtering jaguar, ocelot, caiman, and otter if we did not provide lucrative markets for their skins in Berlin, Paris, and Tokyo.

  • Destruction of our rainforests is not only causing the extinction of plant and animal species, it is also wiping out indigenous peoples who live in the rainforest.
    • Gurupranav G
       
      Useful for my Q4
  • he problem and the solution of the destruction of the rainforest are both economic. Governments need money to service their debts, squatters and settlers need money to feed their families, and companies need to make profits. The simple fact is that the rainforest is being destroyed for the income and profits it yields, however fleeting. Money still makes the world go around . . . even in South America and even in the rainforest. But this also means that if landowners, governments, and those living in the rainforest today were given a viable economic reason not to destroy the rainforest, it could and would be saved. And this viable economic alternative does exist, and it is working today. Many organizations have demonstrated that if the medicinal plants, fruits, nuts, oils, and other resources like rubber, chocolate, and chicle (used to make chewing gums) are harvested sustainably, rainforest land has much more economic value today and more long-term income and profits for the future than if just timber is harvested or burned down for cattle or farming operations. In fact, the latest statistics prove that rainforest land converted to cattle operations yields the landowner $60 per acre; if timber is harvested, the land is worth $400 per acre. However, if medicinal plants, fruits, nuts, rubber, chocolate, and other renewable and sustainable resources are harvested, the land will yield the landowner $2,400 per acre. This value provides an income not only today, but year after year - for generations. These sustainable resources - not the trees - are the true wealth of the rainforest.

Benefits of Deforestation - 0 views

  • One of the easiest benefits of deforestation to spot are the economic ones. Lumber products are one of the most staple constructive materials in human society. Whether it's raw lumber used for making tables and houses, or paper and other wood by-products, we simply cannot live without the use of lumber. Like steel and stone, wood is one of the most basic natural resources, and unlike steel and stone, it is renewable simply by growing more trees. The only real trick to balancing it's consumption is to grow more trees to replace the ones taken.

      that's why it's soo hard to be balanced. Good for my question Q$
  • his benefit of deforestation not only covers the people who cut down trees and process them, but also extends to the people who "clean up" after them. For every patch of forest cut down, arable land becomes available for farmers, or can be used as an area to place urban living sites like apartments, houses, and buildings. The number of people employed by such a construction project are many and varied. Or, if the city/government mandates replanting trees to replace the lost ones, then jobs are also provided for those people who do the seeding after a patch of forest is stripped.

Like steel and stone, wood is one of the most basic natural resources, and unlike steel and stone, it is renewable simply by growing more trees. The only real trick to balancing it's consumption is to grow more trees to replace the ones taken. On a similarly related note, keep in mind that a lot of jobs revolve around the use of lumber. Wood cutters aside, there are those who work in processing plants to make glue from wood sap, process pulp into paper, and others. This is another benefit of deforestation; it opens more job opportunities for people who would otherwise be unemployed. These job opportunities are more than simply a humanitarian concept; society at large would suffer if all of the people working in the wood industry were to suddenly find themselves jobless. This benefit of deforestation not only covers the people who cut down trees and process them, but also extends to the people who "clean up" after them. For every patch of forest cut down, arable land becomes available for farmers, or can be used as an area to place urban living sites like apartments, houses, and buildings.

Or, if the city/government mandates replanting trees to replace the lost ones, then jobs are also provided for those people who do the seeding after a patch of forest is stripped. Thinking about it, the cleared areas are places which provide a lot of potential for growth, and this is yet another benefit of deforestation. As stated above, arable land is valuable, and the act of deforestation to clear a place for farm land provides a much needed additional food source for man. More often than not, the

  • Many species of animal life can be found in the rain forest. Common characteristics found among mammals and birds (and reptiles and amphibians, too) include adaptations to a life in the trees, such as the prehensile tails of New World monkeys. Other characteristics are bright colors and sharp patterns, loud vocalizations, and diets heavy on fruits. Insects make up the largest single group of animals that live in tropical forests. They include brightly colored butterflies, mosquitoes, camouflaged stick insects, and huge colonies of ants. The Amazon river basin rainforest contains a wider variety of plant and animal life than any other biome in the world. The second largest population of plant and animal life can be found in scattered locations and islands of Southeast Asia. The lowest variety can be found in Africa. There may be 40 to 100 different species in 2.5 acres ( 1 hectare) of a tropical rain forest.   When early explorers first discovered the rainforests of Africa, Southeast Asia and South America, they They were amazed by the dense growth, trees with giant buttresses, vines and epiphytes . The tropical vegetation grew so dense that it was difficult to cut one's way through it. It was thought at the time that the soil of a rainforest must be very fertile, filled with nutrients, enabling it to support the immense trees and other vegetation they found. Today we know that the soil of the tropical rainforests is shallow, very poor in nutrients and almost without soluble minerals. Thousands of years of heavy rains have washed away the nutrients in the soil obtained from weathered rocks. The rainforest has a very short nutrient cycle. Nutrients generally stay in an ecosystem by being recycled and in a rainforest are mainly found in the living plants and the layers of decomposing leaf litter. Various species of decomposers like insects, bacteria, and fungi make quick work of turning dead plant and animal matter into nutrients. Plants take up these nutrients the moment they are released. A study in the Amazon rainforest found that 99% of nutrients are held in root mats. When a rainforest is burned or cut down the nutrients are removed from the ecosystem. The soil can only be used for a very short time before it becomes completely depleted of all nutrients.

  • Besides these four layers, a shrub/sapling layer receives about 3 % of the light that filters in through the canopies. These stunted trees are capable of a sudden growth surge when a gap in the canopy opens above them. The air beneath the lower canopy is almost always humid. The trees themselves give off water through the pores (stomata) of their leaves. This process, called transpiration, can account for as much as half of the precipitation in the rain forest. Rainforest plants have made many adaptations to their environment. With over 80 inches of rain per year, plants have made adaptations that helps them shed water off their leaves quickly so the branches don't get weighed down and break. Many plants have drip tips and grooved leaves, and some leaves have oily coatings to shed water. To absorb as much sunlight as possible on the dark understory, leaves are very large. Some trees have leaf stalks that turn with the movement of the sun so they always absorb the maximum amount of light. Leaves in the upper canopy are dark green, small and leathery to reduce water loss in the strong sunlight. Some trees will grow large leaves at the lower canopy level and small leaves in the upper canopy. Other plants grow in the upper canopy on larger trees to get sunlight. These are the epiphytes such as orchids and bromeliads. Many trees have buttress and stilt roots for extra support in the shallow, wet soil of the rainforests. Over 2,500 species of vines grow in the rainforest. Lianas start off as small shrubs that grow on the forest floor. To reach the sunlight in the upper canopy it sends out tendrils to grab sapling trees. The liana and the tree grow towards the canopy together. The vines grow from one tree to another and make up 40% of the canopy leaves. The rattan vine has spikes on the underside of its leaves that point backwards to grab onto sapling trees. Other "strangler" vines will use trees as support and grow thicker and thicker as they reach the canopy, strangling its host tree. They look like trees whose centers have been hollowed out. Dominant species do not exist in tropical rainforests. Lowland dipterocarp forest can consist of many different species of Dipterocarpaceae, but not all of the same species. Trees of the same species are very seldom found growing close together. This bio diversity and separation of the species prevents mass contamination and die-off from disease or insect infestation. Bio diversity also insures that there will be enough pollinators to take care of each species' needs. Animals depend on the staggered blooming and fruiting of rainforest plants to supply them with a year-round source of food.

      Again, another useful peice of info if you are looking at the diversity of plants in the rainforest.
  • There are four very distinct layers of trees in a tropical rain forest. These layers have been identified as the emergent, upper canopy, understory, and forest floor. Emergent trees are spaced wide apart, and are 100 to 240 feet tall with umbrella-shaped canopies that grow above the forest. Because emergent trees are exposed to drying winds, they tend to have small, pointed leaves. Some species lose their leaves during the brief dry season in monsoon rainforests. These giant trees have straight, smooth trunks with few branches. Their root system is very shallow, and to support their size they grow buttresses that can spread out to a distance of 30 feet. The upper canopy of 60 to 130 foot trees allows light to be easily available at the top of this layer, but greatly reduced any light below it. Most of the rainforest's animals live in the upper canopy. There is so much food available at this level that some animals never go down to the forest floor. The leaves have "drip spouts" that allows rain to run off. This keeps them dry and prevents mold and mildew from forming in the humid environment. The understory, or lower canopy, consists of 60 foot trees. This layer is made up of the trunks of canopy trees, shrubs, plants and small trees. There is little air movement. As a result the humidity is constantly high. This level is in constant shade. The forest floor is usually completely shaded, except where a canopy tree has fallen and created an opening. Most areas of the forest floor receive so little light that few bushes or herbs can grow there. As a result, a person can easily walk through most parts of a tropical rain forest. Less than 1 % of the light that strikes the top of the forest penetrates to the forest floor. The top soil is very thin and of poor quality. A lot of litter falls to the ground where it is quickly broken down by decomposers like termites, earthworms and fungi. The heat and humidity further help to break down the litter. This organic matter is then just as quickly absorbed by the trees' shallow roots

  • The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm.) of rain falls yearly. Rain forests belong to the tropical wet climate group. The temperature in a rain forest rarely gets higher than 93 °F (34 °C) or drops below 68 °F (20 °C); average humidity is between 77 and 88%; rainfall is often more than 100 inches a year. There is usually a brief season of less rain. In monsoonal areas, there is a real dry season. Almost all rain forests lie near the equator. Rainforests now cover less than 6% of Earth's land surface. Scientists estimate that more than half of all the world's plant and animal species live in tropical rain forests. Tropical rainforests produce 40% of Earth's oxygen. A tropical rain forest has more kinds of trees than any other area in the world. Scientists have counted about 100 to 300 species in one 2 1/2-acre (1-hectare) area in South America. Seventy percent of the plants in the rainforest are trees. About 1/4 of all the medicines we use come from rainforest plants. Curare comes from a tropical vine, and is used as an anesthetic and to relax muscles during surgery. Quinine, from the cinchona tree, is used to treat malaria. A person with lymphocytic leukemia has a 99% chance that the disease will go into remission because of the rosy periwinkle. More than 1,400 varieties of tropical plants are thought to be potential cures for cancer. All tropical rain forests resemble one another in some ways. Many of the trees have straight trunks that don't branch out for 100 feet or more. There is no sense in growing branches below the canopy where there is little light. The majority of the trees have smooth, thin bark because there is no need to protect the them from water loss and freezing temperatures. It also makes it difficult for epiphytes and plant parasites to get a hold on the trunks. The bark of different species is so similar that it is difficult to identify a tree by its bark. Many trees can only be identified by their flowers. Despite these differences, each of the three largest rainforests--the American, the African, and the Asian--has a different group of animal and plant species. Each rain forest has many species of monkeys, all of which differ from the species of the other two rain forests. In addition, different areas of the same rain forest may have different species. Many kinds of trees that grow in the mountains of the Amazon rain forest do not grow in the lowlands of that same forest.

  • Caring For Our Country The TAFE Caring For Country Program started in 1990 at the request of North Queensland Aboriginal communities who wanted culturally appropriate ranger training. The Diploma level course runs for four years and is equivalent to tertiary education. Aboriginal rangers have unique skills as they are trained to use both traditional knowledge and contemporary management practices to preserve cultural and natural values. Practical skills taught include such things as map reading, site surveys, animal and plant field skills, visitor facility management, first aid and office management. An ecological component includes vegetation management and feral animal control as well as traditional knowledge. Archaeological and anthropological knowledge and techniques are gained in class as well as on sites in the field.
  • Which Way Our Future Aboriginal people are very proud of their indigenous heritage. They want the importance of their culture recognised, respected and protected. To ensure the ongoing survival of their culture, Rainforest Aboriginal people have been negotiating for shared management of their traditional country with government agencies. Rainforest Aboriginal people want to be to be recognised as the traditional land owners of the World Heritage Area with distinct cultures and individual needs. They would like to negotiate plans for their traditional lands and be involved with all aspects of land management decision making, and activities such as tourism and walking tracks planning, fire management, wildlife protection, and on the ground management. Other important goals include ranger training and employment opportunities so that Rainforest Aboriginal people can actively use their customary and contemporary land management knowledge to continue their traditions of managing their country.
  • Aboriginal rangers now work for Aboriginal communities and in some government agencies such as the Queensland Parks and Wildlife Service, looking after rainforest and sea country. Aboriginal rangers are involved in all types of nature conservation and cultural heritage work. They liaise between Elders, Aboriginal community members and government agencies. They build and manage walking tracks for tourists. Rangers carry out surveys on cultural sites and help to manage and protect these sites. They are involved in pest and weed control, and help Government agencies to use controlled fires to maintain the diversity of plants and animals in the World Heritage Area.
  • Rangers also have an important role to play in public education. They visit schools, talk to tourists and the wider community about their work and culture. Cross cultural education and experiences for the wider community and visitors help to promote interracial understanding - an important step towards reconciliation. Aboriginal community rangers are often employed on a part-time basis to work in their communities on land management and cultural heritage protection through funding from the Commonwealth agency, the Aboriginal and Torres Strait Islander Commission (ATSIC) and the Community Development Employment Projects (CDEP). CDEP is similar to the mainstream "work for the dole" (unemployment benefits) program in that these schemes also benefit local communities. A difference is, in some cases, that many Aboriginal people may not have other opportunities to find work or be involved in caring for their country. Many young community rangers find it frustrating to be employed only on CDEP after having done four years of training. Employment of more Aboriginal rangers has the potential to greatly increase the integration of traditional management knowledge and techniques to improve overall management of the World Heritage Area, it is a question of resources. With their Elders, Aboriginal rangers are negotiating with government land management agencies for more permanent, full-time positions managing their country in the Wet Tropics World Heritage Area.

Land mine - Wikipedia, the free encyclopedia - 1 views

  •  
    "A land mine is a target (person or vehicle) triggered explosive weapon . Their non-explosive predecessors (caltrops, stakes and spikes) have been used on the battlefield since ancient times. Landmines were designed to be used to deter, channel, delay and kill an enemy. They have been used in various formats, for centuries and have featured in all major conflicts. Land mines are force multipliers , meaning that they may increase the efficiency of a force without requiring more personnel. The name originates from the practice of mining , where tunnels were dug under enemy fortifications or forces. These tunnels ("mines") were first collapsed to destroy fortifications above, and later filled with explosives and detonated. Land mines generally refer to devices specifically manufactured for this purpose, as distinguished from improvised explosive devices ("IEDs"). The use of land mines is controversial because they are indiscriminate weapons, harming soldier and civilian alike. They remain dangerous after the conflict in which they were deployed has ended, killing and injuring civilians and rendering land impassable and unusable for decades. To make matters worse, many factions have not kept accurate records (or any at all) of the exact locations of their minefields, making removal efforts painstakingly slow. These facts pose serious difficulties in many developing nations where the presence of mines hampers resettlement, agriculture, and tourism. The International Campaign to Ban Landmines campaigned successfully to prohibit their use, culminating in the 1997 Convention on the Prohibition of the Use, Stockpiling, Production and Transfer of Anti-Personnel Mines and on their Destruction, known informally as the Ottawa Treaty . As of 2007, a total of 158 nations have agreed to the treaty. Thirty-seven countries have not agreed to the ban, including China , India , Israel , Pakistan

For maximum psychological impact, they were used in quick succession, one over Hiroshima on August 6, the other over Nagasaki on August 9. These cities had not previously been bombed, and thus the bombs’ damage could be accurately assessed.

  • Although the human cost of the war was tremendous, casualty figures cannot always be obtained and often vary widely. Most experts estimate the military and civilian losses of Allied forces at 44 million and those of the Axis at 11 million. The total number of civilian losses includes the 5.6 million to 5.9 million Jews who were killed in the Holocaust. Of all the nations that participated in World War II, the human cost of the war fell heaviest on the USSR, for which the official total, military and civilian, is given as more than 20 million killed. The United States, which had no significant civilian losses, sustained more than 400,000 deaths.

  • The United States spent the most money on the war, an estimated $341 billion, including $50 billion for lend-lease supplies, of which $31 billion went to Britain, $11 billion to the Soviet Union, $5 billion to China, and $3 billion to 35 other countries. Germany was next, with $272 billion; followed by the Soviet Union, $192 billion; and then Britain, $120 billion; Italy, $94 billion; and Japan, $56 billion. Except for the United States, however, and some of the less militarily active Allies, the money spent does not come close to being the war’s true cost. The Soviet government has calculated that the USSR lost 30 percent of its national wealth, while Nazi exactions and looting were of incalculable amounts in the occupied countries. The full cost to Japan has been estimated at $562 billion.

For example, the larva of the lobster moth (Stauropus fagi), whose larva looks like a scorpion, but is in fact completely defenseless. Many butterflies have large "eye" designs on their wings. This makes them look like the head of a very large animal instead of a harmless butterfly, and scares many predators away.

Tiger - Wikipedia, the free encyclopedia - 0 views

  • Highly adaptable, tigers range from the Siberian taiga, to open grasslands, to tropical mangrove swamps. They are territorial and generally solitary animals, often requiring large contiguous areas of habitat that support their prey demands. This, coupled with the fact that they are endemic to some of the more densely populated places on earth, has caused significant conflicts with humans. Of the nine subspecies of modern tiger, three are extinct and the remaining six are classified as endangered, some critically so. The primary direct causes are habitat destruction and fragmentation, and hunting. Their historical range, which once reached from Mesopotamia and the Caucasus through most of South and East Asia, has been radically reduced. While all surviving species are under formal protection, poaching, habitat destruction and inbreeding depression continue to be threats.
  • Tigers are perhaps the most recognisable of all the cats (with the possible exception of the lion). They typically have rusty-reddish to brown-rusty coats, a whitish medial and ventral area, a white "fringe" that surrounds the face, and stripes that vary from brown or gray to pure black.
  • Main article: Golden tabby A rare golden tabby/strawberry tiger at the Buffalo Zoo. In addition, another recessive gene may create a very unusual "golden tabby" colour variation, sometimes known as "strawberry." Golden tabby tigers have light gold fur, pale legs and faint orange stripes. Their fur tends to be much thicker than normal.[50] There are extremely few golden tabby tigers in captivity, around 30 in all. Like white tigers, strawberry tigers are invariably at least part Bengal. Some golden tabby tigers, called heterozygous tigers, carry the white tiger gene, and when two such tigers are mated, can produce some stripeless white offspring. Both white and golden tabby tigers tend to be larger than average Bengal tigers.

Elephants - 0 views

  • Elephants are the largest land animals. They can weigh over 6,000 kg, or more than the weight of four cars! The one feature that makes an elephant unmistakable is its long trunk. A trunk is an elephant's best tool for sucking up water, digging, grabbing, lifting, sniffing, and breathing. The trunk even has a fingerlike tip that can flick dirt from an elephant’s eye or pick up a single blade of grass. There are three species of elephants. Two species live in Africa and one lives in Asia. All three species are endangered.
  • Asian elephants have an arched body shape. They have triangular ears that do not reach their shoulders and two bumps on their foreheads. Their trunks have a single lip on the upper tip of the trunk. Male Asian elephants are 2-3.5 m tall. Their average weight is about 5,400 kg. Females average about 2.35 m tall and weigh about 2,700 kg. Often, only males have tusk
  • Elephants live in social groups called herds. Herds usually have about 10 to 20 members. Sometimes many herds will meet and form “super herds” of 100 or more elephants. Herds consist mainly of females that are related to each other. A typical herd might include mothers, daughters, aunts, and grandmothers, and a few young males. The oldest female is the herd’s matriarch. She leads the herd to water and finds food and a place to rest. There are also smaller bachelor herds that are made up of adult males.

A male may grow to be twice as large as a female of the same age. In the wild, elephants live to be about 60-years-old.
  • People have always been amazed at the great size and strength of elephants. Long ago, elephants were sometimes used on the battlefield. Soldiers riding atop them would charge at the enemy. The sight of a giant elephant in armor could terrify the enemy soldiers into running away. In Asia, elephants are trained to work for people. They carry people and supplies through tropical forests and help with logging by moving giant logs from place to place. Asian elephants have even been used as taxis to carry people through slow traffic. In India, Thailand, and other Asian countries, elephants are honored as symbols of good fortune. People sometimes decorate elephants and include them as part of traditional religious ceremonies.
  • In the early 1900s, there were more than 5 million elephants in Africa and Asia. Today, there are fewer than 500,000, as a result of hunting (legal and illegal) and habitat destruction. People are the biggest threat to the survival of elephants both in Africa and Asia.

How Can You help Save The Rainforest - 0 views

  • Eat less beef and pork. Fish and poultry have a much lower impact on the environment, while other protein sources including nuts and organic soy are even less damaging to the planet. Think about packaging before you buy products. Individually-wrapped candy generates a lot of trash, while fruits and vegetables are healthier and mean less waste. Turn off lights when you don't need them. When light bulbs burn out replace them with energy-efficient bulbs Do not waste water. Recycle. Encourage your parents to drive fuel-efficient cars and not to overheat their house. Don't let your animals go into the environment when you don't want them any more. Before buying a pet be sure that you are ready to take care of it. Having a pet is a responsibility. Things you can do to help save rainforests: Don't buy products made from wildlife skins Don't buy exotic pets that have been collected from the wild. You can ask pet stores whether animals are "wild-caught" or "captive bred." "Captive bred" animals are more friendly for the environment Buy recycled paper. Don't buy wood products from Indonesia, Malaysia, Brazil, or Africa unless you know they come from eco-friendly suppliers. A good way to know if wood is rainforest-safe is if it has a "certification label." An example of a certification label is "FSC-certified" which means the wood comes from sustainably managed forests. Learn more about rainforests and the plants and animals that live in them. Tell your friends and parents why rainforests are important.

  • A good definition of the arts is given by the Free Dictionary as "imaginative, creative, and nonscientific branches of knowledge considered collectively, esp. as studied academically."[3] The singular term art is defined by the Irish Art Encyclopedia as follows: "Art is created when an artist creates a beautiful object, or produces a stimulating experience that is considered by his audience to have artistic merit."[4] So, one could conclude that art is the process that leads to a product (the artwork or piece of art), which is then examined and analyzed by experts in the field of the arts or simply enjoyed by those who appreciate the arts. The same source states:

      Yeah.......
  • "Gastronomy" is the study of the relationship between culture and food. It is often thought erroneously that the term gastronomy refers exclusively to the art of cooking (see Culinary Arts), but this is only a small part of this discipline; it cannot always be said that a cook is also a gourmet.

      I never even knew about Gastronomy, it might be something to look into.
  • The arts encompasses visual arts, literature and the performing arts - music, drama, dance and film, among others.

  • Ecological footprint Main article: Ecological footprint The ecological footprint is a measure of human demand on the Earth's ecosystems. It compares human demand with planet Earth's ecological capacity to regenerate. It represents the amount of biologically productive land and sea area needed to regenerate the resources a human population consumes and to absorb and render harmless the corresponding waste. According to a 2005 Global Footprint Network report,[7] while inhabitants of high-income countries live off of 6.4 global hectares (gHa), while those from low-income countries live off of a single gHa. For example, while each inhabitant of Bangladesh lives off of what they produce from 0.56 gHa, a North American requires 12.5 gHa. Each inhabitant of North America uses 22.3 times as much land as a Bangladeshi. Of the 12.5 hectares used by the North American, 5.5 is located in the United States, and the rest is found in foreign countries.[7] According to the same report, the average number of global hectares per person was 2.1, while current consumption levels have reached 2.7 hectares per person. In order for the world's population to attain the living standards typical of European countries, the resources of between three and eight planet Earths would be required. In order for world economic equality to be achieved with the current available resources, rich countries would have to reduce their standard of living through degrowth. The eventual reduction of all available resources would lead to a forced reduction in consumption. Controlled reduction of consumption would reduce the trauma of this change.
  • Degrowth and Sustainable Development Degrowth thought is in opposition to all forms of productivist economics. It is, thus, also opposed to sustainable development. While the concern for sustainability does not contradict degrowth, sustainable development is rooted in mainstream development ideas that aim to increase capitalist growth and consumption. Degrowth therefore sees sustainable development as an oxymoron[8], as any development based on growth in a finite and environmentally stressed world is seen as inherently unsustainable. Since current levels of consumption exceed the Earth's ability to regenerate these resources, economic growth will lead to their exhaustion. Those in favor of sustainable development argue that continued economic growth is possible if consumption of energy and resources is reduced. Furthermore, growth-based development has been shown to be more effective in expanding social inequality, concentrating wealth in the hands of a few, than in actually generating more wealth and increasing living standards[9][10]. Critics of degrowth argue that a slowing of economic growth would result in increased unemployment and increase poverty. Many who understand the devastating environmental consequences of growth still advocate for economic growth in the South, even if not in the North. But, a slowing of economic growth would fail to deliver the benefits of degrowth—self-sufficiency, material responsibility—and would indeed lead to decreased employment. Rather, degrowth proponents advocate for a complete abandonment of the current (growth) economic system, suggesting that relocalizating and abandoning the global economy in the Global South would allow people of the South to become more self-sufficient and would end the overconsumption and exploitation of Southern resources by the North
