Food Description of Exploitation Changes to the environment • 90% Madagascan rainforest have been cleared to make farms (to feed a growing population globally) or for fire wood. Watch HERE (15.40) (Indian Ocean – Madagascar) • Overgrazed soil is exposed to wind and rain. This means that the soil can quickly be washed away. Rivers like the Onilahy in Madagascar flood more now as surface runoff is so high causing people to loose homes. Lemars have been driven one reserve – The Berenty Wildlife Reserve.

Food Description of Exploitation Changes to the environment • 90% Madagascan rainforest have been cleared to make farms (to feed a growing population globally) or for fire wood. Watch HERE (15.40) (Indian Ocean – Madagascar) • Fishermen have taken increasingly more and more fish. Overfishing means stocks cant replenish themselves. Cod catches in the North Sea have declined from 300,000 tonnes in 1970 to 20,000 in 2006 but recovered to 70,000 in 2015. • Overgrazed soil is exposed to wind and rain. This means that the soil can quickly be washed away. Rivers like the Onilahy in Madagascar flood more now as surface runoff is so high causing people to loose homes. 400 tonnes of soil are lost per hectare each year in Madasgar. Lemars have been driven one reserve – The Berenty Wildlife Reserve. LO: How are natural resources defined and classified and how do humans exploit and change resources

Quotas (limits) have cased fishermen to throw back fish that they have caught, dead, which they cant land.
