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.

  • oung male elephants leave to join a bachelor herd when they are about 11-years-old. Female elephants, however, stay with their mother’s herd for life. Elephants keep growing their whole lives. 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.

Effect of cutting the rainforest on Earth - 0 views

  • Author: barry a bieda How does the cutting of the rainforest affect Earth? Response #: 1 of 1 Author: mortis Well, we have been cutting rainforests for thousands of years with no permanent damage to the earth at all. Forest people who cut small patches for growing gardens do not hurt the forest because the small plots recover their original growth very quickly: think of the pictures of Mayan ruins in Mexico that are completely covered by forest - these used to be open, active cities! So on a small scale, slash and burn agriculture has no effect whatever on the rain-forest- it is a sustainable use of the forest. However, on a large commercial scale, where bulldozers and flame-throwers are use to convert huge tracts of land into pasture for cattle, the ability of the forest to recover is seriously impaired, destroying the forest for a very long time, if not forever. This kind of unsustainable destructive use affects the earth by taking a large portion of the biosphere out of production - which interrupts the carbon and oxygen cycles, affects local water and soil quality, and causes a decline in the global gene pool by making many species extinct.

Chinese dragon - Wikipedia, the free encyclopedia - 0 views

  • The dragon is sometimes used in the West as a national emblem of China. However, this usage within both the People's Republic of China and the Republic of China on Taiwan as the symbol of nation is not common. Instead, it is generally used as the symbol of culture.The dragon is also a symbol of power, strength, and good luck. Historically, the dragon was the symbol of the Emperor of China. In the Zhou Dynasty, the 5-clawed dragon was assigned to the Son of Heaven, the 4-clawed dragon to the Zhuhou (seigneur), and the 3-clawed dragon to the Daifu. In the Qing Dynasty, the 5-clawed dragon was assigned to represent the Emperor while the 4-clawed and 3-clawed dragons were assigned to the commoners. The dragon in the Qing Dynasty appeared on national flags.[1]

Sierra Leone: Child Soldiers - 0 views

    "While in Sierra Leone a couple of summers ago, I visited Grafton Camp, a facility for recently demobilized child soldiers operated by UNICEF and local partners. Many of the boys, ranging from nine to 16 years of age, had killed people as they fought in a civil war that paused with a fragile cease-fire in 1995. The camp director said that when the youths had been given drugs-most likely, amphetamines-while soldiering, they "would do just about anything that was ordered." Some, he added, were proud of having been effective killers. These boys, who had shortly before been willing to kill and who had never received an adequate foundation of moral development, danced with enormous energy and played cooperative games under the supervision of the camp's counselors. As I watched, it was sobering to think that under certain conditions, practically any child could be changed into a killer. But today, it is even more sobering to see once again how easily children who have been denied education and trained for fighting are manipulated by local political leaders. Fighting has resumed in Sierra Leone following a May coup, and many of the combatants are under 18. They have become part of a continuing cycle of violence. A soldier at seven The nature of armed conflict has changed greatly in recent years. The end of the Cold War ushered in an era of ethnopolitical conflicts that are seldom fought on well-defined battlefields. Conflicts are increasingly internal, and they are characterized by butchery; violence against women, and atrocities sometimes committed by former neighbors. More than 80 percent of the victims are noncombatants, mostly women and children. Increasingly children serve as combatants or as cooks, informants, porters, bodyguards, sentries, and spies. Many child soldiers belong to organized military units, wear uniforms, and receive explicit training, their lethality enhanced by the widespread availability of lightweight assault weapons.

  • The island of Borneo started as a single volcano beneath the sea. Millions of years ago, it erupted. Over time, smaller eruptions and earthquakes joined land together to form an island. Today, Borneo is the third largest island in the world. It is twice the size of Japan. Three countries share the island: Malaysia, Indonesia, and Brunei.

  • Borneo’s rainforests are home to thousands of endemic species of animal, reptile, and insect. These include rhinos, hornbills, macaques, gibbons, tarsiers, and slow lorises. It also has some of the world’s strangest creatures, like flying lizards and frogs (they actually glide using webs of skin). New creatures are still being discovered. In 2005, for example, scientists discovered a large cat-fox mammal in Borneo’s rainforest. Orangutans: Borneo’s Most Famous Animal
  • Borneo’s hilly terrain, rivers, and thick forests have made it difficult to develop until recently. But in the late 1940’s, machines, trucks, and chainsaws were brought to Borneo. These made it possible for settlers from the coastal areas to cut their way into the interior of the island.

RAN.org [Rainforest Heroes]: Tropical Rainforest Animals - 0 views

  • A: Every animal has the ability to protect itself from being someone's next meal. Each species has evolved with its own set of unique adaptations, ways of helping them to survive. BLENDING IN The coloring of some animals acts as protection from their predators. Insects play some of the best hide-and-go-seek in the forest. The "walking stick" is one such insect; it blends in so well with the palm tree it calls its home that no one would notice it unless it moved. Some butterflies, when they close their wings, look exactly like leaves. Camouflage also works in reverse, helping predators, such as boa constrictors, sneak up on unsuspecting animals and surprise them. The three-toed sloth is born with brown fur, but you would never know this by looking at it. The green algae that makes its home in the sloth's fur helps it to blend in with the tops of the trees, the canopy, where it makes its home. But green algae isn't the only thing living in a sloth's fur; it is literally "bugged" with a variety of insects. 978 beetles were once found living on one sloth! STAYING OUT OF SITE The sloth has other clever adaptations. Famous for its snail-like pace; it is one of the slowest-moving animals on earth. (It can even take up to a month to digest its food!) Although its tasty meat would make a good meal for jaguars and other predators, most do not notice the sloth as it hangs quietly in the trees, high up in the canopy. ARMED AND DANGEROUS Other animals want to announce their presence to the whole forest. Armed with dangerous poisons used in life-threatening situations,their bright colors warn predators to stay away. The coral snake of the Amazon, with its brilliant red, yellow, and black coloring, is recognized as one of the most beautiful snakes in the world, But don't admire its beauty too long; its deadly poison can kill within seconds The poison arrow frog also stands out with its brightly colored skin. Its skin produces some of the strongest natural poison in the world, which Indigenous people often use for hunting purposes.Another animal with no friends is the hoatzin. Often called the stinkbird, it produces a horrible smell to scare away potential predators.

  • The perfect partnership - Azteca ants live on the Swollen Thorn Acacia Tree, which offers the ants everything needed for survival - lodging, water, and food for themselves and their young. In return, the ants protect the trees from predators. Whenever the ants feel something moving at the foot of the tree, they rush to fiercely fight the intruder. They also protect it from vines and other competing plants that would otherwise strangle it. As a result, nothing can grow near these trees. They are the only trees with a built-in alarm system!

  • 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.

Afghan cuisine - Wikipedia, the free encyclopedia - 2 views

  • Afghanistan has a wide varying terrain allowing for many different crops. Afghan cuisine is largely based upon the nation's chief crops: cereals like wheat, maize, barley and rice. Accompanying these staples are dairy products (yogurt, whey), various nuts, and native vegetables, and fresh and dried fruits; Afghanistan is well known for its grapes. Afghanistan's culinary specialties reflect its ethnic and geographic diversity and has similarities with neighboring Iran,Tajikistan, Uzbekistan, and Turkmenistan.[1] It is similar to cuisines of the Middle-East and Central Asia.

  • Kabul, the capital of Afghanistan, is a multi-ethnic city and has always been so. As the seat of government for the Afghan kings, food was an important part of royal life. Chefs were commissioned from all over the empire and places afar. They are credited for creating a myriad of dishes, blending different styles and in the process creating the best examples of true Afghan cooking. Their creations include exotic kormas, palaos, sumptuous rice dishes, desserts, and other creative items. These royal chefs passed down their art to the aristocratic denizens of Kabul and they in turn to others. Several attempts were made to record the arts of the royal chefs. Two have been published. The first one, published in Afghanistan in the early 1900s recorded the ingredients and cooking styles of Afghanistan's monarchy. The second, called Aushpazi, by Wali Zikria, published in the United States in English, during the early 1990s, was essentially the cookbook of one of Afghanistan's royal houses.

  • Jaguar Jaguars (Panthera onca) are the largest felid species in the New World and the only member of the genus Panthera, the roaring cats, that occurs in the Americas. They are the third largest cat species, being outsized only by lions (P. leo) and tigers (P. trigris). Although not the largest felid, jaguars have the strongest jaw in relation to head size of any of the cats, a fact that should be remembered whenever planning to capture and immobilize these animals. The body weight of jaguars is 90 - 120 kg for males and 60 - 90 kg for females, with a large variation in body size. Jaguars live in a wide variety of tropical habitats, ranging from montane forest and wet savannah to tropical rain forest and deciduous tropical forest. The largest documented jaguars occur in wet savannahs while jaguars that live in more forested regions tend to be smaller in size

      characteristics of a jaguar.
  • Physical appearance: Jaguars are the largest cat in the western hemisphere. In comparison with the leopard, the jaguar is generally larger and much stockier, with a broad heavy head, much shorter legs and tail (a good visual description might be a leopard on steroids). The background of the jaguar's coat is a tawny-yellow, like many of the Asiatic leopards, and lightened to whitish on the throat and belly. The jaguar is marked with small isolated spots on the head and neck with dark open ring structures, rosettes,on the sides and flank that generally contain one to four dark spots inside the rings. Interestingly, the rosettes of the leopard and the jaguar are almost identical with the exception of the jaguar having spots "inside" the rosettes where the leopard has none. Along the middle of the jaguar's back, a row of black spots may merge into a solid line. According to one Indian myth, the jaguar acquired its spotted coat by daubing mud on its body with its paws.

Slash and burn - Wikipedia, the free encyclopedia - 0 views

  • Slash and burn consists of cutting and burning of forests or woodlands to create fields for agriculture or pasture for livestock, or for a variety of other purposes. It is sometimes part of shifting cultivation agriculture, and of transhumance livestock herding. Historically, the practice of slash and burn has been widely practiced throughout most of the world, in grasslands as well as woodlands, and known by many names. In temperate regions, such as Europe and North America, the practice has been mostly abandoned over the past few centuries. Today the term is mainly associated with tropical rain forests. Slash and burn techniques are used by between 200 and 500 million people worldwide.[1] Older English terms for slash and burn include assarting, swidden, and fire-fallow cultivation. Slash and burn is a specific functional element of certain farming practices, often shifting cultivation systems. In some cases such as parts of Madagascar, slash and burn may have no cyclical aspects (e.g., some slash and burn activities can render soils incapable of further yields for generations), or may be practiced on its own as a single cycle farming activity with no follow on cropping cycle. Shifting cultivation normally implies the existence of a cropping cycle component, whereas slash-and-burn actions may or may not be followed by cropping.

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.

Blue Planet Biomes - World Biomes - 0 views

  • A biome is a large geographical area of distinctive plant and animal groups, which are adapted to that particular environment. The climate and geography of a region determines what type of biome can exist in that region. Major biomes include deserts, forests, grasslands, tundra, and several types of aquatic environments. Each biome consists of many ecosystems whose communities have adapted to the small differences in climate and the environment inside the biome. All living things are closely related to their environment. Any change in one part of an environment, like an increase or decrease of a species of animal or plant, causes a ripple effect of change in through other parts of the environment. The earth includes a huge variety of living things, from complex plants and animals to very simple, one-celled organisms. But large or small, simple or complex, no organism lives alone. Each depends in some way on other living and nonliving things in its surroundings.
