Earth Pollution


How do we pollute the earth?

A.   AIR POLLUTION

Smog hanging over cities is the most familiar and obvious form of air pollution. But there are different kinds of pollution—some visible, some invisible—that contribute to global warming

Air pollution can have serious consequences for the health of human beings, and also severely affects natural ecosystems. Major primary pollutants produced by human activity include Sulphur oxides, Nitrogen oxides, Carbon monoxide, Carbon dioxide, Volatile organic compounds, toxic metals, chlorofluorocarbons, ammonia, odour’s, and radioactive pollutants.



B.   LIGHT POLLUTION

NASA reported that as a result of light pollution, roughly two-thirds of the world’s population can no longer look upwards at night and see the Milky Way

It can also confuse animal navigation, alter competitive interactions, change predator-prey relations, and cause physiological harm which have a huge impact on ecosystems.



C.   WATER POLLUTION

Water is already one of the MOST valuable yet under-priced commodities in the world, as we are simply unable to live without it…and it is estimated that over 14,000 people DIE every day as a result of water pollution.

Water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks or uses or lives (in) it.


D. OCEAN POLLUTION

Over 80% of marine pollution comes from land-based activities in the form of toxic chemicals (Industrial, agricultural, household cleaning, gardening, and automotive products regularly end up in coastal waters), fertilizer runoff, sewage disposal, seas of garbage, and a small percentage from oil spills.

An enormous island of trash twice the size of Texas is floating in the Pacific Ocean somewhere between San Francisco and Hawaii.
