Planet Acts: Water
Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers, and groundwater. Water pollution results when contaminants are introduced into the natural environment. Water pollution is the leading worldwide cause of death and disease, e.g. due to water-borne diseases. All acts that help avoid or reduce water pollution or acts that improve water quality, supply, or treatment are linked to this sub-category.
