Environmental Pollution
Human activities polute environmental media (air, water or soil). All human industrial, agricultural, recreational, and domestic activities are capable of introducing "contaminants" to the environment, thereby negatively impacting the atmospheric air, water and land/soil. The impacted media may later constitute hazards (chemical or physical) to humans, wildlief and plants.
Air pollution
Exhausts to the atmosphere from airplanes, vehicles and industrial plants; open burning; gaseous (e.g. methane) releases from open dumps etc. Since our atmosphere is universal, it can be concluded that the earth's air medium is universally contaminated,
Water pollution
Most of our water bodies have been impacted through our water transportation activities; heavy oil spills and leaks to water bodies, direct deposition of wastes to water bodies and contamination through seepages from landfill or dump sites
Land pollution:
Lands used for industrial activities (gas stations, manufacturing factories, etc) are left contaminated after use. Several releases of chemicals, oil, and other substances to the land. Contaminated sites abound everywhere in major locations of the world. several debris and wastes that constitute dangers are left on the sites
.
A contaminant is any substance that impacts the environment negatively, thereby causing negative changes (or pollution) to the atmosphere".
"Contamination is dangerous to the safety and health of humans, wildlife and the environment"
