How do humans affect precipitation?
Greenhouse-gas emissions have made the Northern Hemisphere wetter. Human activity has made the weather wetter in a large slice of the Northern Hemisphere, say researchers. It has also made the regions just south of the Equator wetter, and those just north of it drier.
How do human activities cause water pollution?
What human activities cause water pollution? Human activities that generate domestic sewage and toxic waste cause water pollution by contaminating water with disease-causing microorganisms and poisonous substances. Oil spills are another source of water pollution that have devastating impacts on surrounding ecosystems.
What are the effects of pollution?
Pollution may muddy landscapes, poison soils and waterways, or kill plants and animals. Humans are also regularly harmed by pollution. Long-term exposure to air pollution, for example, can lead to chronic respiratory disease, lung cancer and other diseases.
What are the pros and cons of water pollution?

What are the human activities that destroy the environment?
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
What is water pollution and its causes effects and prevention?
Water pollution can be defined as the contamination of water bodies. Water pollution is caused when water bodies such as rivers, lakes, oceans, groundwater, and aquifers get contaminated with industrial and agricultural effluents. … The effects of water contamination can be felt for years to come.
How do humans destroy rivers?
Sulfur dioxide and nitrous oxide emitted from factories and power stations enter river systems through acid rain. Sewage and effluent are discharged into rivers in some areas. Pollution can lower the pH of the water, affecting all organisms from algae to vertebrates. Biodiversity decreases with decreasing pH.
