Pollution is the addition of substances to the ecosystem that have detrimental effects. The document discusses four main types of pollution: air, water, land, and noise. Air pollution involves accumulation of substances in the atmosphere that endanger health or living organisms. Water pollution is the introduction of chemicals, physical materials, or biology into fresh or ocean water that degrades quality and harms organisms. Land pollution is degradation through misuse of soil from poor agriculture, mining, dumping waste, and improper urban waste disposal.
