| Global
Warming is caused by gaseous compounds
that when present in the atmosphere, absorb
infrared light and trap heat radiation from earth. The possible consequences of global warming are
rising sea levels resulting in loss of land area, salt intrusion in
groundwater reservoirs, increased risk of droughts, flooding, soil
erosion and storms. |
Acidification
of the environment is due to emissions of acids. The consequences of
acidification is degradation of some materials such as metals, limestone
and concrete, and damage to trees and life in lakes and
rivers. |
Nutrient Enrichment of the environment is caused by
nutrient emissions to the environment. The consequences of nutrient enrichment is
increased algal growth in waters and loss of nutrient poor landscapes on
land.
|
Photochemical
Smog Formation is caused by atmospheric emissions
of nitrogen oxides and volatile organic compounds (VOCs). The consequences of photochemical smog are harm to human health,
degradation of many materials, and reduced yield of crops in agriculture. |
Oxygen Depletion is caused by emissions of organic matter
to the water environment. Oxygen depletion occurs in the water because
degradation of the organic matter requires oxygen. The possible
consequences are unpleasant smell and loss of plants, fish and bottom animals. |
