What reason of deforestation?
Reasons for deforestation:
-Climate change
-Desertification
-Soil erosion
-Fewer crops
-Landslides
-Water pollution
-Loss of biodiversity
-Floods
-Increase of carbon dioxide
Soil erosion:
-While a natural process accelerates with deforestation
-Trees and plants act as a natunal barrier to slow water as it runs off the land
Desertification:
-If trees are removed, the area can become much warmer and drier, which may result in desertification
Fewer crops:
-There is less water in the air to be returned to the soil -This causes dryer soil and the inability to grow crops
Landslide:
-Without trees, land will be very unstable and easily down the slope
-Large-scale deforestation has increased the risk nof landslides in mountainous areas
Water pollution:
- Without tree roots holding the soil in a forest, soil will run into the river
-Can lead to the death of aquatic plants and animals and leaching of fertilisers into the water table leads to eutrophication
Loss of biodiversity:
-Brought about irreversible consequences of gene pool depletion
Floods:
-Trees prevent sediment runoffs and forests hold more water than farms or grasslands
Increase of carbon dioxide:
-Its Extreme Effect on Global Warming From logging, agricultural production and other economic activities, deforestation adds more atmospheric CO2 than the sum total of cars

When did mass deforestation begin?
-That's because, starting in the late 1960s, Brazil began cutting down and burning forest at an alarming rate
-An area the size of France
