ENVIRONMENTAL POLLUTION AND ITS IMPACT

ENVIRONMENTAL POLLUTION AND ITS IMPACT

Pollution or environmental pollution is the entry or inclusion of a living creature, energy substances, and or other components into the environment or changes in order of the environment by human activity or by processes nature so that the quality of the environment down to the level of be certain that cause less environmental or can no longer function as intended (Law Principles of Environmental Management No. 4 of 1982). Contamination may arise as a result of human activities or caused by nature (volcanoes, gas toxic).

Environmental science usually discuss pollution caused by human activity, which can be prevented and controlled. Due to human activities, environmental pollution is inevitable. Contamination The environment can not be avoided. Which can is to reduce pollution, control pollution, and increasing awareness and concern society to the environment so as not to pollute the environment. Substances or materials that may result in  pollution called pollutants. The terms of a substance called when the existence of pollutants can cause harm to living beings. For example, carbon dioxide at levels of 0.033% in the air benefited plants, but if higher than 0.033% can damaging effects.

A substance can be called pollutants if:

1. The amount exceeds the normal amount.

2. Being at the wrong time.

3. Being in the wrong place.

The nature of the pollutants are:

1. Damaging for a while, but when it reacts the substance does not damage the environment again.

2. Damage in a long time. Examples Pb does not spoil when the concentration is low. However, within a period long, lead can accumulate in the body until damaging levels.

Impact of Environmental Pollution

1. Extinction of species

As described, pollutants harmful to biota water and land. Various types of animals were poisoned, then die. Various species of animals have immunity are not the same. There are sensitive, some are resistant. Young animals, larvae are sensitive animals pollutant. There are animals that can adapt so immune to the pollutants, those that do not. Although animals adapt, should note that animal adaptation rate limits. When the limit is exceeded, the animal will die.

2. Blasting Hama

The use of insecticides can also be deadly predators. Because predators extinct, then the insect pest will growing out of control.

3. Extinction Environmental Balance

The extinction of certain species can alter patterns of interaction in in an ecosystem. Food chains, nets food and fluid energy into changing. As a result, environmental balance disturbed. Recycling materials and recycling biogeochemical be disturbed.

4. Reduced Soil Fertility

The use of deadly insecticide soil fauna. This matter can reduce soil fertility. The use of fertilizers continuously can cause the soil to become acidic. Case This also can reduce soil fertility. As well  the occurrence of acid rain.

5. Toxicity and Disease

People who consume vegetables, fish, and groceries contaminated can be poisoned. there are dead world, there is a damaged liver, kidney, suffered cancer, nervous system damage, and even causing defects in the offspring.

6. Concentration Biological

The process of elevated levels of contaminants through the body creature known as biological concentration (in the language English is known as biomagnificition.

7. Formation of Ozone Hole and the Greenhouse Effect

The formation of the ozone hole and the greenhouse effect is a global problem that is felt by all mankind. This is due to contaminants can spread and cause effects elsewhere.
