in the environment
Ecology is an integrated and dynamic study of the environment.
Land use changes (Deforestation & Degradation)
Construction and Excavation
Green House Effect
Degradation can be deforestation, desertification, soil erosion, mineral depletion, or chemical degradation (acidification and salinization)
Pesticides & insecticides
Increased to 2.5 million tons annually
World Health Organization estimated in 1992 that 3 million pesticide poisonings occur annually, causing 220,000 deaths.
Decompositionof organic matter in the soil
Much of the methane emitted into the atmosphere is caused by the decomposition of organic matter in wet soils such as rice paddies.
Wet or anaerobic soils also lose nitrogen through denitrification, releasing the greenhouse gasnitric oxide.[
Human ActivityConstruction Dams
River line and Coastal Erosion
Nuclear weapons emit large amounts of thermal radiation as visible, infrared, and ultraviolet light
Anthropogenic changes .
Chief hazards are burns and eyeinjuries
Burns visible on a people in Hiroshima during the blast.
Coolant in refrigerators and air conditioners
The propellant in aerosol dispensers
The foaming agent in the production of plastic foam cups and containers
An extremely destructive form of pollution, and the environment suffers from its effects.
