Deforestation Facts
- Forests cover 30% of land
- Forests the size of Panama are lost each year
- At the current rate the worlds forest could be gone in a hundred years
- Cut down for money
- Not all is intentional
- Wild fires and over grazing
- Loss of habitat for species
- 70% of animals and species that live on land live in forests
- Climate change- loss of trees cause soil to dry out
- Trees help absorb greenhouse gases
- Solution- stop cutting down trees
- Trees filter carbon dioxide, act as shelters
- Causes
- economic benefits
- Urban purposes
- lumber used for material, furniture and paper products
- To grow crops
- Grazing land for cattle
- Fuel- firewood or charcoal
- Effects- erosion, disrupts of water cycle, loss of biodiversity, flooding and drought, climate change
- Erosion- exposing soil to sun (drying it out), when rain comes nutrients wash away, replanting impossible in the dried out soil
- Disruption of water cycle- trees pull up water with roots and reemits into atmosphere
- Loss of biodiversity- 50 to 100 species lost each day
- Flood and drought- trees absorb and store large amounts of water in rain, without trees floods followed by droughts
- Climate change- trees absorb carbon dioxide, when cut down that carbon is released into the air as carbon dioxide
