Agricultural use has been eliminating natural vegetation and forests.
The result was enhanced pollution in streams due to lack of filtration.
Reduction of photosynthesis due to forest loss.
Loss of organic material (food supply) on stream banks and therefore loss in biodiversity.
Tree cover loss in streambanks result in less shade, causing water temperature to increase.
Warm water holds less oxygen.
The majority of aquatic organisms are cold-blooded, and cannot regulate their body temperature.
Water temperature influences biological activities and directly affects aquatic life survival.
