Eaten Any Wood Today? You may have! And you probably brushed your teeth with it. Chances are you even dressed with wood. Skeptical? Don’t be. We’re all familiar with forest products like lumber, furniture, and paper. But few of us realize how many different things we regularly use that are manufactured from trees. In fact, more than 5,000 wood and paper products make our lives better each day. Here are just a few: Fruits and NutsFruit from trees such as apples and peaches, as well as nuts from trees such as walnuts, are all favorite products grown on trees. Bandage StripsTree gum, sap extracted from trees, makes the adhesive on bandage strips stick to your skin. Baseball BatsThe white ash tree is a hardwood that is used to make baseball bats—including, of course, Kentucky’s own Louisville Slugger! CandlesTree gum can be used to make candles. ClothingCellulose is used to produce rayon and acetate, which can be used to make a vast array of clothing such as ties, shirts, dresses, and suits. CombsWood pulp and cellulose can be used to make plastics for items such as hair combs. Cough SyrupCellulose products, used for their even-flowing consistency, often thicken cough syrups and other liquid oral medicines. CrackersNot only is the cracker box a product of trees, but the crackers themselves can be made using a high-purity cellulose. CrayonsGum extracted from trees can help make crayons. Eyeglass FramesCellulose wood fibers are dissolved and can then be formed into molded articles like eyeglass frames. Football HelmetsEthyl cellulose is responsible for making the hard, impact-resistant plastics found in football helmets. GumGum and synthesized essential oils from trees can be used to make chewing gum. Ice CreamIce cream can be made with cellulose, which comes from trees. LipstickCellulose can help give lipstick its easy-apply texture. MakeupMakeup sometimes gets its creamy texture from the tree derivative cellulose. Maple SyrupSap from trees is used to make syrup. Milk CartonsMilk cartons can be made from pulpwood. Nail PolishNail polish contains nitrocellulose to help make the polish glossy when it dries. NewspaperPulpwood is used to make newspaper, wrapping paper, book paper, and wallpaper. PaintMethylcellulose, a product made from cellulose, gives paints their thick consistency. Parmesan CheeseCellulose powder is sometimes used to help keep grated Parmesan cheese pieces from caking together. PencilsTree logs are used to make pencils. PerfumeTree bark is used to make “tall oil,” which cosmetic companies can use to make perfumes. Photo FilmLogs are reduced to pulp, and the pulp is processed to create cellulose acetate chemicals that can be used to make photographic film. ShampooMethylcellulose can be used to thicken shampoo and conditioner. Without it, they would just be soapy water! SpongesCellulose is broken down into chemicals that can be used to make sponges. TiresTree-produced chemicals can be used for making the synthetic rubber found in tires. Toilet PaperWood pulp makes paper products such as toilet tissue, paper towels, napkins, and facial tissue. ToothpasteCellulose can be used in toothpaste to give it a paste-like consistency.

It is estimated that nearly half of the world's estimated 10 million species of plants, animals, and microorganisms will be destroyed or severely threatened over the next quarter-century due to rainforest deforestation.

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."

When a medicine man dies without passing his arts on to the next generation, the tribe and the world loses thousands of years of irreplaceable knowledge about medicinal plants.

tropical rainforests are considered a type of tropical wet forest (or tropical moist broadleaf forest) and may also be referred to as lowland equatorial evergreen rainforest

and may also be referred to as lowland equatorial evergreen rainforest

Rainforests are home to half of all the living animal and plant species on the planet.[2] Tropical rain forests are called the "world's largest pharmacy" because over one-quarter of modern medicines originate from its plants.

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.

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.

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.

Scientists believe that there is such a great diversity of animals because rainforests are the oldest ecosystem on earth.

Many animals species have developed relationships with each other that benefit both species. Birds and mammal species love to eat the tasty fruits provided by trees. Even fish living in the Amazon River rely on fruits dropped from forest trees. In turn, the fruit trees depend upon these animals to eat their fruit, which helps them to spread their seeds to far-off parts of the forest.

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.

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 arts of ancient Greece have exercised an enormous influence on the culture of many countries, particularly in the areas of sculpture and architecture.

There were several interconnected traditions of painting in ancient Greece. Due to their technical differences, they underwent somewhat differentiated developments. Not all painting techniques are equally well represented in the archaeological record.

The most respected form of art, according to authors like Pliny or Pausanias, were individual, mobile paintings on wooden boards, technically described as panel paintings. The techniques used were encaustic (wax) painting and tempera. Such paintings normally depicted figural scenes, including portraits and still-lifes; we have descriptions of many compositions. They were collected and often displayed in public spaces. Pausanias describes such exhibitions at Athens and Delphi. We know the names of many famous painters, mainly of the Classical and Hellenistic periods, from literature (see expandable list to the right). Unfortunately, due to the perishable nature of the materials used and the major upheavals at the end of antiquity, not one of the famous works of Greek panel painting has survived, nor even any of the copies that doubtlessly existed, and which give us most of our knowledge of Greek sculpture. The most important surviving Greek examples are the fairly low-quality Pitsa panels from circa 530 BC, and a large group of much later Graeco-Roman archaeological survivals from the dry conditions of Egypt, the Fayum mummy portraits, together with the similar Severan Tondo. Byzantine icons are also derived from the encaustic panel painting tradition.

Why Do We Need To Conserve?One answer is very simple. We need to conserve to make certain we have resources for ourselves and for people in the future. Conservation will allow future generations to enjoy natural resources such as clean rivers and lakes, wilderness areas, a diverse wildlife population, healthy soil, and clean air. Resources Are Necessary for Life! Many natural resources are necessary for our survival. It may be difficult to imagine that we could ever run out of fresh water, clean air, and good soil for growing food. But in some places this is already happening.

Using less paper, reusing paper, and recycling paper saves trees and water. Recycling aluminum cans will save money, resources, and prevent pollution. For example, it takes much less energy to recycle an aluminum soft drink can than it does to make a new one. Making energy uses up resources like oil and coal. So just by recycling the aluminum cans you use, you become an instant conservationist!

What's Made From Trees? It's no wonder people have used wood products for centuries. Wood is durable, renewable, recyclable, biodegradable, energy efficient and environmentally friendly. What would your life be like without wood? Things made from trees touch our lives every day. More than 5,000 products come from trees. And there are many uses for wood that may surprise you. Trees not only provide wood and paper, but other less obvious forest products such as chemicals and other materials that are impor- tant ingredients in plastic filler, varnishes, tooth- paste, shoe polish, foam rubber and much, much more. Tree bark is used for mulches, soil conditioners, medicines and cosmetics. Once a log reaches a mill, there is virtually no waste. The entire log is used to produce either lumber, paper, particleboard products or energy. Nationally, forest product companies are one of the most efficient of all manufacturing industries because they use sawdust and other wood waste to furnish up to 75% of their energy needs.   Idaho Forest Products Commission©2005 All rights reserved.

Farmland is made.

The wood cut down is sold as timber and used as fuel.

There are also social reasons for cutting down the trees. Transport links. Roads and railways are needed to move goods and people. Settlements. Modern cities such as Manaus in Brazil and Jakarta in Indonesia have been developed in areas that were once were tropical rainforest.

Use less gasoline and plastic.Gasoline and plastic are two things that are made from petroleum, or oil. A lot of oil comes from the rainforests through a process called extraction. Since oil extraction is very harmful to the rainforests, using less oil products can help save the rainforests.

Eat less red meat.One big reason rainforests are being destroyed is for beef. Millions of acres of rainforest are slashed and burned, which means that the land is set on fire in order to clear it. The cleared land is then turned into grass pastures for cows.

Use less paper.Since most paper comes from trees, using less paper can help save the rainforests. Use recycled 100% post-consumer waste (PCW) paper whenever possible.

he first bomb was exploded in a test at Alamogordo, New Mexico, on July 16, 1945. See also Manhattan Project. Two more bombs had been built, and the possibility arose of using them to convince the Japanese to surrender. President Harry S. Truman decided to allow the bombs to be dropped. 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. U.S. estimates put the number killed or missing as a result of the bomb in Hiroshima at 60,000 to 70,000 and in Nagasaki at 40,000.

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.

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.

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

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.

The identification, ongoing protection and presentatiosn of cultural values is paramount. This includes cultural sites and their traditional knowledge (sometimes referred to as intellectual and cultural property rights) such as food and medicine resources. They want to be able to hunt and gather their traditional foods and other resources, while managing impacts which have the potential to impair these activities through disturbance and habitat destruction. Other important aspirations relate to the future of Rainforest Aboriginal people's communities and their survival into the 21st century. Many Rainforest Aboriginal people want to get more involved in cultural tourism because it means they can present their culture and benefit economically. One of the most heart-felt aspirations Rainforest Aboriginal people have is to get secure title to their traditional lands to ensure the integrity and survival of their cultures.  

They wear little clothing because it is always warm in the rainforest. They make their clothing from leaves and things they find in the rainforest, too. Their way of life is in danger because of the destruction of the rainforest that they live in. The government has tried to teach them how to farm, but the Mbuti don't want to change the way they live.
