Question

Impacts of human activities on the quality of river water

Answer 1

Answer:

Explanation: One of the most serious threats to water resources is the degradation of ecosystems, which often takes place through changes to landscapes such as the clearance of forests, the conversion of natural landscapes to farmland, the growth of cities, the building of roads, and surface mining

Activities such as farming, clearing forests, building roads, and mining can put too much soil and particulate matter in rivers. This sediment can harm plants and animals by carrying toxic chemicals into the water, smothering fish eggs and small organisms used by fish as food, raising water temperature, and reducing the amount of sunlight penetrating the water.

Wastes that people dispose of can pollute the air, the land, and water resources. They affect the quality of rainwater and of water resources
