Human Impact on the natural environment
Waste that is not recycled has to go somewhere.
The table shows that happens to some common types of rubbish.
Eventually the environment breaks down the rubbish or spreads it around so much that it becomes safe.
Domestic refuse-Buried underground or burnt
Faeces - Cleaned at sewage works and the remains passes into rivers
Waste Gases- Passed into the atmosphere and spread out to safe levels
The Damage done by waste depends on:
- HOW MUCH IS PRODUCED
- HOW DANGEROUS IT IS
- HOW QUICKLY THE ENVIRONMENT CAN DEAL WITH IT
Sometimes the environment cannot deal with the waste quickly…
