Deforestation o To give reasons for deforestation, and explain why this is damaging to the environment

NEWS bite deforestation of Brazilian Rainforest o o News Bite (5 th December 2008): As the deforestation of the Brazilian Amazon increases for the first time in four years, the Brazilian government and global community discuss how to tackle the problem at the UN Climate Change conference. What are the 2 main reasons the rainforest is destroyed? http: //espresso/clipbank/servlet/asset? asset. ID=7475

Trees o Trees are a valuable resources for both animals and humans o Humans use them for a variety of purposes, including: n Fuel (being burnt) n Building material n Space (removing forests give valuable space for farming)

Sustainable? o Forestry is sustainable, as long as all of the trees that have been cut down are replaced (new trees planted) o However, if this is not done, this leads to deforestation (where the amount of forest continually shrinks)

Deforestation o There are many reasons for rainforest destruction, including: n Fuel n Farming (Mc. Donalds and Burger King buy up a great amount of land within South America for cattle) n Homes

Deforestation o Deforestation can lead to some devastating consequences: n Destruction of habitats (decreasing biodiversity) n Extinction of rare plants (with may contain medicinal properties) n Flooding due to increased soil erosion n Atmospheric changes (rises in carbon dioxide)

Rate Of Loss o The map shows deforestation rates over the last 10’ 000 years o In recent times there has been a huge increase in rainforest destruction around 17 -20 million hectares are cut each year (an area the size of a football pitch every 2 seconds)! o The rainforest contains ~50% of all species on Earth and produces ~40% of the worlds atmospheric oxygen

Task o Using the resources available in groups of 3 or 4 choose one of the 2 sides – either for rainforest destruction or against it o Produce a report (via presentation) that lists all the factors you think are important, e. g. “we should preserve the rainforest because…” or “we should allow some deforestation because…” o You will need to present your findings, and the reasons you have picked your side as well as question the direct impact you have on the rainforest

Arguments
