Potty The Amazonian People's Struggle Indigenous people such as the Yanomamo and Kayapo have been living in the Amazon rainforest for as long as 32,000 to 39,000 years. There were about 6.8 million indigenous people when the first Europeans first arrived to South America in the 16th century. Presently, following the results of Europeans bringing persecution, slavery and diseases to the Southern American continent, and continued deforestation of their homes, the Brazilian Amazon is home to between 280,000 and 350,000 indigenous people. According to the anthropologist Darcy Riberio, 55 indigenous populations vanished in the first half of the 20th century alone. Greenhouse Gas Trees? According to the World Carfree Network (WCN), cars and trucks account for about 14 percent of global carbon emissions, while analysts attribute about 15 percent to deforestation. How does this occur? When trees are chopped down, they release the carbon they are storing into the atmosphere, where it joins with greenhouse gases from other sources and contributes to global warming. Dried Up Drinking Water The water cycle of an ecosystem can be disrupted by deforestation. Trees extract water from the earth through their roots and release this water into the air. When trees are removed, the water in the can no longer be extracted efficiently and the region may become drier. Deforestation reduces the amount of water in the soil and moisture in the atmosphere. The removal of trees also cause erosion and can cause flooding or landslides. Aquifers are affected as well by deforestation. Deforested lands also lose the ability to intercept and retain precipitation properly, and, as Mouth Potty Mouth by the NUMBERS 36 football fields of forest a minute are lost to deforestation. This is equal to 12 to 15 million hectares of forest a year. (Dried Up Drinking Water continued) a result, water may pool more easily and cause rapid runoff that can cause flash flooding and localized floods. According to one study, in deforested regions in north and northwest China, the average annual precipitation decreased by more than 30% between the 1950s and 1980s. One-fifth of the world's fresh water is found in the Amazon Basin. The Rainforest: A Living Medicine Cabinet For thousands of years, tropical rainforest plants have been use to improve the health of humans both in the rainforest and around the world. Presently over 7,000 medical compounds prescribed by doctors are derived from plants that grow in the rainforest. These plants include: Trumpet Tree: All parts of the tree are used in traditional medicine to treat respiratory illnesses and rheumatism. Periwinkle: Extracts of the periwinkle plant have two of the most active tumor fighting agents. It is used widely and very successfully in treating leukemia and Hodgkin's Disease. Lemongrass: Has antibacterial and antifungal properties which aid in treating fevers, colds, and coughs. Lemon grass tea is a very popular herbal tea. Annatto Tree: Oil extract of the Annatto tree is used for protection against UV rays. The destruction of rainforests threaten the availability of these, and many other, lifesaving plants. Positive Deforestation? Despite the previously discussed negative consequences of deforestation, some argue that good can come from the deforestation of rainforests. Deforesting the Amazon can be positive for the soy, timber and biofuel industry because there is a lot of potential for money to be made in previously nonagricultural areas. However, the gain from harvesting the timber is only in the terms of immediate cash compensation. After that, the logger will have to wait for more trees to mature, which is not good for the forest, or the loggers profit margin. Additionally, the removal of vegetation exposes the soil to heat and rain. When forests are cleared, soil cover, which consists mainly of vegetation, is removed as well. This exposes the bare soil to extreme conditions produced by the sun's heat and rainwater. The Future of Deforestation In November of 2012, world leaders met at a U.N. climate conference in Doha, Qatar, where the topic of tropical rainforests was discussed. Tremendous pressure’s face countries that push for deforestation: urbanization, increasingly meat-based diets, population growth, and the demand for timber and agricultural products. What can be done to try and combat the continuing threat of deforestation? Experts at the conference agreed that unless all countries take responsibility and address the continuing issues of deforestation, then the state of the world’s tropical forests will continue to decline. Countries can do this by evaluating where the world’s growing population will acquire food and natural resources.
