- Removing trees and vegetation that shade streams, permitting sunlight to raise the temperature of these waters.

Factories.
Decay of organic matter

The second type of thermal pollution is much more widespread. Streams and small lakes are naturally kept cool by trees and other tall plants that block sunlight.
People often remove this shading vegetation in order to harvest the wood in the trees, to make room for crops, or to construct buildings, roads, and other structures.
Left unshaded, the water warms by as much as 10 Celsius degrees (18 Fahrenheit).
