+ Tropical rain forest Why is tropical rain forest so important for us?
+ Consequences of deforestation: Importance to local people
+ Homes of many native people TRF provides food by practising shifting cultivation. The Yanomami people live in the Amazon rainforest. They obtain their food from farm plots cleared from the forest, river and hunt.
+ Habitats of plants and animals More than 1/3 of all species in the world live in the Amazon Rainforest. home to about 2.5 million insect species, tens of thousands of plants, and some 2000 birds and mammals. at least 40,000 plant species, 3,000 fish, 1,294 birds, 427 mammals, 428 amphibians, and 378 reptiles have been scientifically classified in the region. Scientists have described between 96,660 and 128,843 invertebrate species in Brazil alone. Largest Biodiversity
+ Consequences of deforestation: Importance to soil
+ Protecting top soil from erosion & flooding DEFORESTATION Heavy rain washes away the top soil (soil erosion) Soil flows into river The channel becomes shallow FLOODING
+ Consequences of deforestation: Importance to local climate
+ Maintain local climate More trees More evapo- transpiration More condensation More precipitation Normal water cycle Less trees Less evapo- transpiration Less condensation Less precipitation Local drought
+ Importance of tropical rain forest to local region Provide food for local people Protect soil and prevent flooding Provide habitats for wildlife and plants Maintain water cycle and local climate
