Poverty in Asia - 0 views

  • Poverty in Asia,caste and progress. In this FAO Poverty In Asia map, Darker is Poorer but some light areas are just 'no data' - see our Poor in a Rich World page.A majority of the worlds poorest people today are in Asia - partly because it holds a majority of the world's population. Of course some Asian countries like Japan and South Korea are not as poor as others like India and Cambodia, with Asian poverty being concentrated in South Asia.  Asian poverty1. Poverty in some Asian countries is largely due to the pressure of population growth on scarce resources and inadequate governments allowing strongly negative caste discrimination. 2. Education, medicine, clean water and sanitation are often inadequate also3. In some Asian countries land ownership being problematic also encourages poverty. 4. Asia till recently attracted less foreign investment than Latin America, but more of it has been stable longer-term European investment. Some of Asia has shown good progress on poverty in recent years, like China and South Korea. (in China noteably helped partly by controls on population growth)  But Asia, holding the largest populations, still has many extreme poor. The current world recession is also causing family remittances from overseas workers or migrant workers to fall. As more migrant workers lose jobs in Western Europe and the USA, remittances to their poor families in Central Asia are being hit hard. And the likely prospect for aid in the short term is a sharp fall.

  • An increase in tourism has increased economic support, allowing more revenue to go into the protection of the habitat. Tourism can contribute directly to the conservation of sensitive areas and habitat. Revenue from park-entrance fees and similar sources can be utilised specifically to pay for the protection and management of environmentally sensitive areas. Revenue from taxation and tourism provides an additional incentive for governments to contribute revenue to the protection of the forest. Tourism also has the potential to increase public appreciation of the environment and to spread awareness of environmental problems when it brings people into closer contact with the environment. Such increased awareness can induce more environmentally conscious behavior. Tourism has had a positive effect on wildlife preservation and protection efforts, notably in Africa but also in South America, Asia, Australia, and the South Pacific.[14]

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.

Degrowth - Wikipedia, the free encyclopedia - 0 views

  • 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

Introduction to Biomes - 0 views

shared by Yen Yu C on 02 Sep 09 - Cached
  • Biomes are the major regional groupings of plants and animals discernible at a global scale. Their distribution patterns are strongly correlated with regional climate patterns and identified according to the climax vegetation type. However, a biome is composed not only of the climax vegetation, but also of associated successional communities, persistent subclimax communities, fauna, and soils.

  • The global distribution pattern: Where each biome is found and how each varies geographically. A given biome may be composed of different taxa on different continents. Continent-specific associations of species within a given biome are known as formations and often are known by different local names. For example,the temperate grassland biome is variously called prairie, steppe, pampa, or veld, depending on where it occurs (North America, Eurasia, South America, and southern Africa, respectively). The general characteristics of the regional climate and the limitations or requirements imposed upon life by specific temperature and/or precipitation patterns. Aspects of the physical environment that may exert a stronger influence than climate in determining common plant growthforms and/or subclimax vegetation. Usually these factors are conditions of the substrate (e.g., waterlogged; excessively droughty, nutrient-poor) or of disturbance (e.g., periodic flooding or burning). The soil order(s) that characterize the biome and those processes involved in soil development. The dominant, characteristic, and unique growthforms; vertical stratification; leaf shape, size, and habit; and special adaptations of the vegetation. Examples of the last are peculiar life histories or reproductive strategies, dispersal mechanisms, root structure, and so forth. The types of animals (especially vertebrates) characteristic of the biome and their typical morphological, physiological, and/or behavioral adaptations to the environment.

Rainforest Biomes - 0 views

  • 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.

      A great peice of info if you want to look at the biodiversity of animals in a rainforest
  • 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.
    • Gurupranav G
       
      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.

  • The Amazon is the world's largest and most famous rainforest. The Amazon River Basin is roughly the size of the forty-eight contiguous United States (the United States not including Alaska and Hawaii) and includes parts of eight South American countries: Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, and Suriname. The basin is drained by the Amazon River, the world's largest river (and the second longest river after the Nile). The Amazon is home to more species of plants and animals than any other ecosystem on the planet and perhaps 30% of the world's species are found there. Some of the better known animals found in the Amazon include the jaguar, tapir, and many kinds of monkeys.

  • Because there are so many creatures living in the rainforest, there is a great deal of competition for food, sunlight and space. Some animals became very specialised. This means that they adapted to eating a specific plant or animal that few others eat. For example, parrots and toucans eat nuts, and developed big strong beaks to crack open the tough shells. Leafcutter ants climb tall trees and cut small pieces of leaves which they carry back to their nest.The leaf pieces are about 50 times their weight.The ants bury the leaf pieces, and the combination of the leaves and the ants' saliva encourages the growth of a fungus, which is the only food these ants eat. Sometimes there are relationships between animals and plants that benefit both. Some trees depend on animals to spread the seeds of their fruit to distant parts of the forest. Birds and mammals eat the fruits, and travel some distance before the seeds pass through their digestive systems in another part of the forest. One problem with specialisation is that if one species becomes extinct, the other is in danger too unless it can adapt in time. The dodo, a flightless bird of Mauritius, became extinct in 1681. Today there are just 13 calvaria trees left on the island, each over 300 years old, and nearly at the end of their life. Scientists realised that the seeds had to pass through a dodo's digestive system before they could germinate. It seemed that the tree species would also become extinct, but scientists tried domestic turkeys and have successfully managed to germinate some seeds.Many rainforest animals use camouflage to 'disappear' in the rainforest. Stick insects are perfect examples of this. There are some butterflies whose wings look like leaves. Camouflage is of course useful for predators too, so that they can catch prey that hasn't seen them. The Boa Constrictor is an example of a camouflaged predator. The South American three-toed sloth uses camouflage and amazing slowness to escape predators. Green algae grows in the sloth's fur, which helps camouflage it in the forest canopy. Sloths are among the slowest moving animals of all (inside too, as it takes about a month to digest food). They hang from branches in the canopy, and are so still that predators such as jaguars don't see them. Some animals are poisonous, and use bright colors to warn predators to leave them alone. There are several species of brightly colored poison arrow frogs. Native Central and South American tribes used to wipe the ends of their arrows onto the frog's skin to make their arrows deadly

  • If It's Been Around So Long, Why Have I never Heard Of It Before Now? I guess there are still a lot of secrets in the South American Rainforests. The recent explosion in the popularity of Jagua body art just goes to show that there are many possibilities still out there that the outside world has not even noticed. More importantly it goes to show that local traditional knowledge is incredibly important to the whole world, not just the local people of the Rainforest. So every effort should be made to help preserve it.

  • Where Can I Get Hold Of Some Jagua Then? Well you could take a trip out to the rainforests and search it out yourself. But if your going to paint from an unripe fruit, you only have a short time to do it, before the stain stops working. But recently Jagua Body Art products like Jagua Paint and Jagua Gel have been made readily available to you so you can create your own jagua tattoos whenever you like.

  • Jagua is a tropical fruit that is used for traditional body art. The unripe jagua fruit juice is painted on the skin making elaborate and striking jagua body art. It's a really great type of body paint because it can last for a few weeks, just like henna body art. So technically jagua is actually a stain and not a paint.

Yanomamo Indians In The Modern World - Term Papers - Soufiane - 0 views

shared by Ameya R on 10 Sep 09 - Cached
  • The Yanomamo (Yah-no-mah-muh) also called Yanomamo, Yanomami and Sanuma (which means ‘Human Being') are deep jungle indigenous Indians living in the Amazon basin in both Venezuela and Brazil. The Yanomamo are believed to be the most primitive, culturally intact people in existence in the world. In spite of that, they exist within the modern period by use of technology which is well-adapted to their environment.
  • They number approximately 12,000 people and are distributed in some 125 widely scattered villages in the upper Amazon basin of Brazil and in the South of Venezuela (South America). They live in small villages that are separated by many miles of unoccupied land. The villages can be as small as 40 to 50 people or as large as 300 people grouped by families in one large communal dwelling called a Shabono; this disc shaped structure with an open-air central plaza is an earthly version of their god's Abode. The villages are autonomous but constantly will interact with each other. The quote following read in the book Yanomamo Warfare is intended to give more details about number of Yanomamo "The Yanomamo are by far the most numerous and best described of the four major divisions of Yanomamo. Population estimates put their numbers at 6,00

Anacondas of the Rain Forest - 0 views

  • The anaconda is an amphibious snake.  It gives birth to live young.   Some anacondas, which live in the water, can reach up to 30 feet in length!  The anaconda is most active at night.    Although they are not venomous, they defend themselves by inflicting severe bites, but kill by constriction.  They swim well and kill their prey by strangling them.  If that does not work, they drown them.  They are usually able to last two years without eating.  They feed on birds and small animals.  They will kill animals as large as jaguars.    The anaconda is the largest snake in the world.  This snake is in the boa family.  It is found in stream banks and swamps in South America, east of the Andes from Columbia and Venezuela to Northern Bolivia, and South Central Brazil.  There is little known about the anaconda.

Deforestation - 0 views

  • What is Deforestation Deforestation is defined as the destruction of forested land. It has proved to be a major problem all over world. However, the rates of destruction of forests are particularly high in the tropics. Causes of Deforestation The causes of deforestation vary form place to place. The most common causes, however, are logging, agricultural expansion, wars, and mining, Effects of Deforestation Deforestation has been the cause of many problems facing the world today such as erosions, loss of biodiversity through extinction of plant and animal species, and increased atmospheric carbon dioxide. Importnace of Vegetation Deforestation consequently decrease the supply of oxygen found on earth. Oxygen is essential to the existence of all living things and without it every living creature (including humans) will not be able to sustain life. In addition, forests provide homes for many important species such as the Northern Spotted Owl which can only survive in the northwestern United States . Furthermore, forests prevent desertification by replenishing nutrients in the land. These are just a few reasons why forests are soon important.

World War II - MSN Encarta - 0 views

  • Hitler’s Change of Plan The Russians were doing exactly what the German generals had wanted, sacrificing enormous numbers of troops and weapons to defend Moscow. Hitler, however, was not satisfied, and over the generals’ protests, he ordered Army Group Center to divert the bulk of its armor to the north and south to help the other two army groups, thereby stopping the advance toward Moscow. On September 8 Army Group North cut Leningrad’s land connections and, together with the Finnish army on the north, brought the city under siege. On September 16 Army Group South closed a gigantic encirclement east of Kyiv that brought in 665,000 prisoners. Hitler then decided to resume the advance toward Moscow and ordered the armor be returned to Army Group Center.

      So THE IS THE COLD DESERTS. i THOUGHT THEY WERE SMALLER. i SHOULD LEARN MORE ABOUT THE COLD DESERTS
  • A desert is a hostile, potentially deadly environment for unprepared humans. In hot deserts, high temperatures cause rapid loss of water due to sweating, and the absence of water sources with which to replenish it can result in dehydration and death within a few days. In addition, unprotected humans are also at risk from heatstroke.
  • Humans may also have to adapt to sandstorms in some deserts

  • The jaguar is a near threatened species and its numbers are declining. Threats include habitat loss and fragmentation. While international trade in jaguars or their parts is prohibited, the cat is still regularly killed by humans, particularly in conflicts with ranchers and farmers in South America.
  • The jaguar prefers large prey and will take deer, capybara, tapirs, peccaries, dogs, foxes, and sometimes even anacondas and caiman. However, the cat will eat any small species that can be caught, including frogs, mice, birds, fish, sloths, monkeys, and turtles;

  • Like all cats, the jaguar is an obligate carnivore, feeding only on meat. It is an opportunistic hunter and its diet encompasses 87 species.
  • It begins eating at the neck and chest, rather than the midsection. The heart and lungs are consumed, followed by the shoulders.

The grassland biome - 0 views

  • SavannaSavanna is grassland with scattered individual trees. Savannas of one sort or another cover almost half the surface of Africa (about five million square miles, generally central Africa) and large areas of Australia, South America, and India. Climate is the most important factor in creating a savanna. Savannas are always found in warm or hot climates where the annual rainfall is from about 50.8 to 127 cm (20-50 inches) per year. It is crucial that the rainfall is concentrated in six or eight months of the year, followed by a long period of drought when fires can occur. If the rain were well distributed throughout the year, many such areas would become tropical forest. Savannas which result from climatic conditions are called climatic savannas. Savannas that are caused by soil conditions and that are not entirely maintained by fire are called edaphic savannas. These can occur on hills or ridges where the soil is shallow, or in valleys where clay soils become waterlogged in wet weather. A third type of savanna, known as derived savanna, is the result of people clearing forest land for cultivation. Farmers fell a tract of forest, burn the dead trees, and plant crops in the ashes for as long as the soil remains fertile. Then, the field is abandoned and, although forest trees may recolonize, grass takes over on the bare ground (succession), becoming luxuriant enough to burn within a year or so. In Africa, a heavy concentration of elephants in protected parkland have created a savanna by eating leaves and twigs and breaking off the branches, smashing the trunks and stripping the bark of trees. Elephants can convert a dense woodland into an open grassland in a short period of time. Annual fires then maintain the area as a savanna.
