why do people fossil fuels get extracted and how do they exploit the environment ?
- fossil fuels produce energy
- extraction and production of energy from fossil fuels
- burning coal to produce energy
why does fishing happen and how does it exploit the environment ?
- take fish for food from oceans
- overfishing
why does farming happen and how does it exploit the environment ?
- produces food
- land is overgrazed
why does deforestation happen and how does it exploit the environment ?
- palm oil is needed due to rising demand for food
- impacts on biodiversity
- increases soil erosions where heavy rain falls on cleared land
- water pollution affects drinking water quality
how is reduced biodiversity caused by exploitation ?
areas of land where biodiversity is large are reduced and therefore reduces biodiversity
how is soil erosion caused by exploitation ?
areas of trees are cut down and rain lands on the soil causing soil erosion
how is reduced water quality caused by exploitation ?
- drinking, washing and producing manufactured goods
- water we use comes from ground water sources
- rivers are used for disposal of sewage
how is reduced air quality caused by exploitation ?
more fossil fuels are burnt ruins air quality
where in the UK do you find water supply ?
doesn’t tend to fall in places which have high concentration of population so certain areas of UK can become short of water in summer

- 24.6 million tonnes industrial minerals
- 13.9 million tonnes fossil fuels
- 90.1 million tonnes of minerals extracted under the sea

North America
which parts of the world use the least energy ?
Africa
which parts of the world use the least water ?
Sahara Desert
