      so this is about the rainforest importance
  • The Amazon Rainforest By Alec The Amazon rainforest has many different plants that can be used as herbal medicines. Some of the most important medicines come from the Amazon. They have been used for hundreds and hundreds of years. These plants can be deadly if taken in large doses, but in small doses they can be very helpful. They can be used to cure headaches, skin irritation, high blood pressures, and many other diseases. Here are some of them. White Trillium The white trillium has three petals, three sepals, and three leaves. If the leaves are chewed, it can help cure snake bites. If the plant’s petals are chewed, they can help ease childbirth, and the sepals if chewed are used to help cure fevers. Cinchona Tree (Cinchona officinalis) The bark of this tree is used to make Quinine, a medicine that helps treat Malaria, a serious disease. A number of various other chemicals can also be made from Cinchona, and these chemicals include cinchonine, cinchonidine and quinidine. However, quinine has been replaced by other drugs such as chloroquine and mefloquine, and now quinine is rarely used to treat malaria. Foxglove (Digitalis purpurea) The leaves of this plant contain digitalis, a substance used to treat heart problems. When taken in large doses it can produce palpitations and dizziness, but when taken in smaller doses it can help the heart beat more slowly. This medicine had many effects, and sometimes it cured in miraculous ways, but it mostly produced violent reactions, occasionally killing because it was taken in very large doses. The foxglove tea is used as a morning tea to aid in birth control. Opium Poppy (Papaver somniferum) The opium poppy is used to make Morphine and Codeine, two drugs that are used as painkillers. The opium gum may be crudely refined and smoked, or converted to morphine and heroin.

      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."

  • At least 80% of the developed world's diet originated in the tropical rainforest. Its bountiful gifts to the world include fruits like avocados, coconuts, figs, oranges, lemons, grapefruit, bananas, guavas, pineapples, mangos and tomatoes; vegetables including corn, potatoes, rice, winter squash and yams; spices like black pepper, cayenne, chocolate, cinnamon, cloves, ginger, sugar cane, tumeric, coffee and vanilla and nuts including Brazil nuts and cashews.
    • Chloe W
       
      WOW! It may not be the most unique foods and plants, but it is interesting that most of our things come from rainforests!
    • Chloe W
       
      Hopefully, this will come in handy for my central idea.
  • 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.
    • Yen Yu C
       
      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.

  • It is almost always raining in a rainforest. Rainforests get over 80 inches (2 m) of rain each year. This is about 1 1/2 inches (3.8 cm) of rain each week. The rain is more evenly distributed throughout the year in a tropical rainforest (even though there is a little seasonality).
    • Luke Whitehouse
       
      Weather conditions and climate.
  • The range of temperature in a tropical rainforest is usually between 75° F and 80° F (24-27° C).
  • Once damaged, the soil of a tropical rainforest takes many years to recover.
  • Tropical rainforests cover about 7% of the Earth's surface and are VERY important to the Earth's ecosystem. The rainforests recycle and clean water. Tropical rainforest trees and plants also remove carbon dioxide from the atmosphere and store it in their roots, stems, leaves, and branches. Rainforests affect the greenhouse effect, which traps heat inside the Earth's atmosphere. Some of the foods that were originally from rainforests around the world include cashew nuts, Brazil nuts, Macadamia nuts, bananas, plantains, pineapple, cucumber, cocoa (chocolate), coffee, tea, avocados, papaya, guava, mango, cassava (a starchy root), tapioca, yams, sweet potato, okra, cinnamon, vanilla, nutmeg, mace, ginger, cayenne pepper, cloves, oranges, grapefruit, lemons, limes, passion fruit, peanuts, rice, sugar cane, and coconuts (mostly from coastal areas).
    • Luke Whitehouse
       
      Importance of the rainforests
  • The soil of a tropical rainforest is only about 3-4 inches (7.8-10 cm) thick and is ancient.
  • EMERGENTS: Giant trees that are much higher than the average canopy height. It houses many birds and insects. CANOPY: The upper parts of the trees. This leafy environment is full of life in a tropical rainforest and includes: insects, birds, reptiles, mammals, and more. UNDERSTORY: A dark, cool environment under the leaves but over the ground. FOREST FLOOR: Teeming with animal life, especially insects. The largest animals in the rainforest generally live here.

  • What We Can Do To Save Them Learn and Share Information The first step toward saving the rainforests is to learn about them. Through reading we can explore the wonders of the rainforests without ever visiting them. Once we learn about them we need to share our knowledge with others. Letters to our congressional representatives can influence those in power and encourage discussion on the rainforest. And by talking to friends about the rainforests another person can become active in saving the them. Join Groups We can join a conservation group. The group can tell us what needs to be done to save the rainforests and how we can help. Or we can volunteer with the local zoo, nature center, botanical garden, or museum. We can learn a lot from the professionals that work there. Begin at Home Our own homes provide many chances to help save the rainforests. We can recycle all reusable materials. We can learn to use products made from rainforests in a thoughtful way. And we can protect living things in our own backyard. The plants and animals there also need protection. Ask Questions We can protect illegal trade of animals and plants from the wild by asking questions. We need to ask store owners if the plants and animals they sell were taken from the wild. Unless we ask questions, illegal trade will continue. Illegal trade leads to endangered species and extinction. Think Globally And we can encourage our local or national conservation organizations to help save the rainforests. It is necessary for all of us to be aware of and help with saving the rainforests. Although the rainforests cover on ly a small area of the world, far away from many of our homes, they have an effect on all of us.

Tropical Rainforests - 0 views

  • 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

FastFacts, Respecting Our Wood Resource - 0 views

  • Respecting and ExtendingOur Wood Resource Today's near-zero-waste sawmills use computers and sophisticated equipment such as laser-guided saws to get the most lumber out of each log. In fact, today's mill recover about twice as much lumber from each log as did mills at the turn of the century. The wood fiber that is not usable as lumber is recovered and processed into other valuable products. These "by-products" of lumber manufacturing can become particleboard , oriented strandboard paneling, or other engineered-wood products. Byproducts are also used to fuel cogeneration plants which produce electricity for the sawmills. And wood fiber also is used to make such products as plastic filler, shoe polish, toothpaste, varnish, foam rubber, and much more!

  • •  Natural rubber (or latex): used to make many rubber products from electronic components to condoms. Rubber was responsible for the first economic cycle of development in the Amazon rainforest. Natural rubber is extracted from tall trees called "Seringueiras" and still today is a major activity for many families. •  Brazil-nut: the nut is actually a seed. The Brazil-nut is one of the biggest nuts of the world and is exported all over the planet. Local populations use this nutritious seed to make all sort of food and condiments; •  Guarana: is a small berry-like fruit that is very sweet and juicy. You can taste it in natural refreshments anywhere in Brazil , they are also used to make sodas. Brazilians are very fond of their guarana sodas and it's something they usually miss when living outside Brazil . Because of that you can find it in any city that has a Brazilian community like Miami , New York or Paris. People use Guarana to stay awake and active in parties and raves, since guarana has an effect similar to caffeine without the problems related to it. Nowadays some companies sell Guarana as a weigh loss substance, although its value for weight loss has not been proven.
