General Information Human Interaction with the TRF Biome
Deforestation increases C02 in the atmosphere • Wood is 50% carbon • 1859-1990 deforestation released 122billion tonnes of carbon into atmosphere • Led to global warming • Without GW temp would be -18 degrees
Lungs of the earth • Trees clean the air by absorbing harmful dust and particles, sulphur dioxide and nitrogen • Less trees means air quality declines • Higher C02 lead to many changes • Extreme weather patterns, floods in australia last year, extreme heat now, mudslides in Brazil, droughts in saheletc
Biodiversity • Rainforest – 50% of worlds biodiversity in 7% of landmass • 137 species disappear every day • Losing cures to cancer and aids • 1 in four prescription drugs are derived from plants by pharmaceutical ind.
Indigenous People • Displacement • Unique knowledge of Rainforest and plants is being lost • 53,000 square miles of rainforest lost in 1980’s
Soil Erosion • Slash and Burn is used to clear forest – releases nutrients into soil • Increase productivity for short period • Being leached by heavy rain • In 3 years soil can be infertile • Requires artificial fertiliser but too expensive so more land is cleared • Regeneration of forest is slow and soil is eroded
