Pollution is defined as the addition of substances to the environment at a faster rate than is necessary and causing harm to both the environment and living organisms. Controlling the release of harmful elements into nature is accomplished through measures such as air pollution control, wastewater treatment, solid waste management, and so on. Household and industrial waste are the primary sources of land pollution. Water is contaminated to the point where there is no access to clean water, and polluted water bodies are hazardous to the organisms that live in them. The main source of air pollution is the combustion of fossil fuels. The PowerPoint presentation contains interesting facts about the topic.
