Pollution and Degradation of the Lithosphere
Transcript of Pollution and Degradation of the Lithosphere
Pollution and Degradation
Effects of Farming
Excessive Use of Pesticides
Continual Crop Rotation
How Does This Happen?
Definition: loss of soil fertility
- World population increasing
- Need more food
Led to: heavy farming machines
- side effect of this machinery
This leads to:
- Soil lacking oxygen
- Rain run off
No time for the soil
- kill micro-organisms, insects etc
- reduce soil balance
- decrease biodiversity
Definition: abnormal presence of a
harmful substance in an environment
Leaks from gas-stations
Leak water from landfills
- sulphuric acid and nitric acid
mixed in with the rain water
- acidified soil can't keep plant nutrients
- kills micro-organisms
- slows plant growth
