Dumping waste in the water impacts so much. I read that scientists have found plastic in the deepest parts of the ocean. Cutting down trees causes soil erosion by and into bodies of water.
Locally, our lake owner's society wants to dredge the lake. While this can help prevent flooding since the lake is becoming much more shallow and increase space for boats, the water will become turbid and could affect the fish, turtles, cranes, geese, etc that depend on the lake. Questioning where the dredging will go and how long it will last.
