Rainforest:deforestation E10-1 Elia
Summary • Deforestation is to remove trees of rainforest. • Causes of deforestation are agriculture, logging, overgrazing, road building and fire. • Deforestation leads desertification and destruction of animal’s habitat.
How Does this Problem Affect Us? • Decrease of trees leads increase of CO2 in the air. Then because of greenhouse effect, global warming become worse. • Land become weak and fall down easily. • Deforestation promotes desertification. • Destruction of animal’s habitat leads loss of biodiversity.
Solutions • To designate national park or sanctuary • Don’t waste paper. • To restrain indiscreet logging • International programs (UN-REDD, UNFF etc.)
Statistics • During 20 years, world forest cover decreased from 4168 million hectares to 4033 million hectares.
Possible Solutions • Rotational grazing : to divide paddock into some parts and to use a part of paddock to graze by rotation. It help land to return to life.
What Will be the Result if This Problem ISN’T solved soon? • Most of rainforest will become a big desert. • There is no enough food. • Animals lose their habitats and start to be exterminated. • CO2 in the air will increase.
