ACID RAINS AND ITS IMPACTS
<p>ACID RAIN The deposition of acidic components in wet forms such as fog, snow or hail and in dry forms such as acidic particles from the atmosphere is called acid rain. Major reason is:- Acid rain results when sulphur dioxide (SO2) and nitrogen oxides (NOX) already present in the atmosphere react with water, oxygen and other chemicals to […]</p>

CAUSES AND EFFECTS OF POLLUTION
<p>Air Pollution Causes of Air Pollution Pollutants released directly from identified sources are caused by both natural (for example, dust storms and volcanic eruptions) and manmade phenomena (emission from vehicles, industries, etc.) These are referred to as “primary pollutants.” There are five major contaminants that account for about 90% of worldwide air pollution. Secondary pollutants […]</p>

THREATS TO BIODIVERSITY
<p>Habitat Loss Due to unsustainable resources use, productive lands like the forest, savannah, rainforest, etc. are degrading at a higher pace. This is the most important cause which is driving animals and plants to extinction. An example of habitat loss comes from Tropical Rain Forests. At one time they were covering more than 14% of […]</p>

<p>On Environment The lack of trees leads to a greater amount of greenhouse gases being released into the atmosphere. Healthy forests absorb CO2from the atmosphere, acting as valuable carbon sinks. The trees help in regulating the water cycle. In deforested areas, there’s less water within the air to be returned to the soil. This then causes […]</p>
