- Great for humans but means we affect the environment more
- Due to modern medicine and farming methods which have reduced the number of people dying from disease/hunger
- Increasing demands on the Environment
- Pressure on the environment- we take resources we need to survive
- People demanding higher standard of living so we use more raw materials and energy in manufacturing processes.
- We are going to run out of some resources e.g oil
- Producing more waste
- WATER; sewage and toxic chemicals pollute our waters affecting organisms in them. Fetilisers washed into water too
- LAND; Toxic chemicals for farming e.g pesticides. Bury nuclear waste underground and dump a lot of waste in landfill sites.
- AIR; Smoke and gases pollute air, e.g SO2 = acid rain
- More people, less land for animals and plants
- We reduce land by building, farming, dumping waste and quarrying for metal ores
- World population rising very quickly
