The Lithosphere
Pollution and Degradation
Effects of Farming
Acid Rain
Their Fix?
Excessive Use of Pesticides
Continual Crop Rotation
Soil Depletion
Soil Compaction
How Does This Happen?
Soil Depletion
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
& nutrients
- Rain run off
No time for the soil
to regrow
Extra fertilizer
- 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
Mining waste
- sulphuric acid and nitric acid
mixed in with the rain water


- acidified soil can't keep plant nutrients
- kills micro-organisms
- slows plant growth
