Final answer:
Diffuse pollution is a type of water pollution that occurs when contaminants enter water supplies from large and more spread out areas. Organic matter, phosphates, and nitrates from human and farm animal waste can contribute to diffuse pollution by supporting the growth of algae and microorganisms. Measures should be taken to reduce nonpoint source pollution and minimize the impact of diffuse pollution on water quality and aquatic life.
Step-by-step explanation:
Diffuse pollution is a type of water pollution that occurs when contaminants enter water supplies from large and more spread out areas, known as nonpoint sources. Unlike point source pollution, which comes from identifiable and localized locations, diffuse pollution is more challenging to control due to its low concentration, multiple sources, and larger volume of water.
Organic matter, phosphates, and nitrates from human and farm animal waste can contribute to diffuse pollution by supporting the growth of algae and microorganisms in water bodies. This excessive nutrient load can lead to eutrophication, which is the increase in chemical nutrients that promotes excessive growth of algae, depletes oxygen, and harms fish and other animal populations.
Diffuse pollution is a significant threat to water resources and ecosystems worldwide. It is important to take measures to reduce nonpoint source pollution and minimize the impact of diffuse pollution on water quality and aquatic life.
