However, If we don't act now there won't be any rainforests left to study, especially if you recall the extinction facts Rainforests make legal money from tourism, natural rubber and other natural resources. Illegally, in some cases, people are logging these rainforests to make money. STW Scientific Economic Save The world, Save The Rainforests A funny fact about rainforests is that rainforests actually only cover 12% of the earths surface. Yet it is home to around 50 and 90 % of the worlds species. Because of the deforestation at least 1 species becomes extinct EVERY DAY. Today the extinction rate of species is 400 times faster than ever in the history of Earth. The Importance of Rainforests Today at least a quarter of all the planets medicine comes from rainforests. These medicines were actually first discovered by the indigenous people of the rainforests. Medicines There is A LOT of food that comes from today’s rainforests. Some foods that we use today that originated in rainforests include : Coffee, cocoa, many fruits and nuts, spices, rice and a lot more products such as gum, dye, rubber and resins. In fact of an estimated 75,000 edible plants only 150 make it into today’s market. Food Fact: There were an estimated ten million Indians living in the Amazonian Rainforest five centuries ago. Today there are less than 200,000. In Brazil alone, European colonists have destroyed more than 90 indigenous tribes since the 1900's. With them have gone centuries of accumulated knowledge of the medicinal value of rainforest species. As their homelands continue to be destroyed by deforestation, rainforest peoples are also disappearing. Most medicine men and shamans remaining in the Rainforests today are 70 years old or more. Each time a rainforest medicine man dies, it is as if a library has burned down. This is because they have rare knowledge of herbal remedies and medicines that could help cure many diseases such as the E.coli outbreak in europe. As mentioned before, there are many more natural resources and food produces from rainforests which are means that rainforests make money. Also mentioned before, there is all the natural medicines and other herbs which are valubale ingredients in medicines Social Rainforests are very important socially and morally. Being surrounded by the natural environment that is a rainforests, people feel at peace with the world. As the UN, you try to encourage world peace, rainforests can help with that goal. Rainforests tourism can help make people feel happy as well. We should also protect the indigenous people of the rainforest as part of Human rights. Definition of ecosystems "A biological community of interacting organisms and their physical environment" Now that you know the definition of an ecosystem, let's find out how rainforests fit into that A biological community A Biological community is a group of living organisms that work together to survive. Rainforests fit the first part of the ecosystem defeinition because of all the wild and exotic creatures that live together and survive off each other. Of interacting organisms Interacting organisms are any living things that interact with each other. In rainforests, the food chain forces species to interact thus fulfilling this part of the definition And their physical environment The main parts of a rainforest, the parts that characterizes one, are what proves this part. The trees and the heavy rainfall. Physical environment is the surrounding area so it includes the shrubs, bushes, vines, etc. Fact ave he orld Tribes in the Amazon Examples of tribes in the Amazon are the Kaiapo, the Piraha, the Yanomami/ Yanos, Huaorani/ Waodani and The Tagaeri.
