Enviromantal Problems
What is enviroment?
The environment is our physical surroundings. This includes both human (man-made), social, and physical (natural) features.
Kinds of enviromental problems
Some of the largest problems now affecting the world are acid rain, air pollution, global warming, hazardous waste, ozone depletion, smog, water pollution, overpopulation, and rain forest destruction.
Causes of acid rain
Acid rain is caused by the burning of fossil fuels. Burning oil, gas and coal in power stations releases sulphur dioxide (SO2) into the atmosphere.
Effects of acid rain
Acid rain increases the acidity levels of rivers, lakes and seas. Acid rain increases the acidity levels of soils. Acid rain can erode buildings and monuments.
Causes of global warming
Global warming is the worldwide warming of the atmosphere. Global warming is caused by the increases in the amount of carbon dioxide and other gases being released into the atmosphere by the burning of fossil fuels.
Effects of global warming
Sea levels rises due to the melting of the ice caps. This will cause flooding in many low-lying areas of the world.
Greenhouse effect
The greenhouse effect is a natural phenomenon that controls the balance of heat within the Earth’s atmosphere. It is the process whereby the natural layer of gases in our atmosphere traps a small percentage of the sun’s radiation reflected from the Earth’s surface.
Water pollution
Pollution makes streams, lakes, and coastal waters unpleasant to look at, to smell, and to swim in. Fish and shellfish harvested from polluted waters may be unsafe to eat. People who ingest polluted water can become ill, and, with prolonged exposure, may develop cancers or bear children with birth defects.
Petroleum products
Petroleum products get into water mainly by means of accidental spills from ships, tanker trucks, pipelines. Many petroleum products are poisonous if ingested by animals, and spilled oil damages the feathers of birds or the fur of animals, often causing death.
Pesticides and herbicides
Chemicals used to kill unwanted animals and plants, for instance on farms or in suburban yards, may be collected by rainwater runoff and carried into streams, especially if these substances are applied too lavishly.
