Pollution Overview and Impact

Pollution is environmental contamination by waste, chemicals, and harmful substances.
Major forms of pollution include air, water, and land pollution.

Key contributors: wildfires, volcanoes, industrial chemicals, and primarily the burning of fossil fuels (coal, oil, natural gas).
Sources of fossil fuel combustion: factories, electrical plants, automobiles.
Air pollution can release solid particles (ash and soot) and harmful gases, leading to:
- Smog, characterized by hazy air that impairs visibility.
- Health issues such as cancer and asthma.
- Acid rain that damages ecosystems.
- Global warming, indicated by a gradual increase in Earth's average temperature.
- Ozone layer depletion, which protects Earth from harmful solar radiation.

Visible causes include the dumping of garbage and sewage into water bodies (creeks, rivers, lakes, oceans).
Industries may discharge oils and toxic chemicals into water sources.
Indirect causes include agricultural practices:
- Chemicals used as fertilizers can poison groundwater.
- Pesticides and herbicides can contaminate surface water, threatening aquatic life.

Littering is a direct and visible form of land pollution that disrupts habitats for flora and fauna.
Chemical pollution from agriculture and industries can accumulate in soil:
- Contamination can affect plants and animals and pose health risks to humans who consume them.

Governments, environmental organizations, and individuals are actively combating pollution.
Legislative efforts aim to prevent the release of hazardous chemicals into the environment.
Transitioning to renewable energy sources (solar, wind, hydro) reduces reliance on fossil fuels.
Community recycling initiatives help minimize waste and promote sustainable material use.
