1. Eutrophication

2. Eutrophication
excessive nutrients in a body of water, frequently due to runoff from the land, which causes a dense growth of plant life & death of animal life from lack of oxygen

3. extra terminology:
healthy stream = has lots of living things, especially macro(large) invertebrates (animals without backbones)
buffer zone = plants/vegetation around the banks of rivers to absorb & slow runoff water
river delta = triangle shaped, where a river slows before it enters a large body of water, high deposition
estuary = ecosystem where fresh water mixes with salt water
turbidity = measure of how clear water is; high turbidity is a sign of an unhealthy stream
