The environment gets polluted when we add harmful substances in it, in the form of solid, liquid or gas. The main types of pollution are – air, water, soil, noise, thermal, nuclear and radiation. Its cause is prolonged and continuous development and human activity to fulfill endless materialistic demands of an ever increasing world population.

Causes of Environmental Pollution

Polluted Air – industries consume and run on coal, charcoal, petroleum its products and natural gas. After consumption they produce energy to manufacture industrial goods. In the tail end of the produce a large quantity of toxic gases are belched out or exhaled as byproducts or side-effects of these natural resources. These poisonous gaseous contents are namely – sulphur dioxide, carbon monoxide, carbon dioxide and minute untreated dust particles. Motor vehicles pose a similar danger from the fumes they emit.

Lacking Forests and Trees -Trees are a major source of cleaning the air. They inhale CO2 discharged in the atmosphere and exhale oxygen that creatures breathe. And as getting a sore throat by yelling on top of the roof top: stop cutting trees, stop demolishing forests; for the very same reason. But of course they are necessary for us to adorn our houses as wood items. The value of a tree should be as high as a priceless diamond or an exclusive prohibited animal fur. Our refrigerators and other cooling electronics release CFC, which is a gas that drills a hole in earth’s ozone enfolding that is slowly ripping it apart. It is exposing us to the dangers of excessive heat, which the world calls and terms it as climate change.

Contaminated Water – the chemical residues of fertilizers and pesticides used in farming mixes in the soil and runs off into water. The solid and liquid forms of residual wastes from industries; urban garbage and untreated sewage and soiled water will all flow into our water bodies. And that is contaminating our rivers, seas and oceans that pose a danger to our marine life. This will include accidental oil spills from sea tankers, carriers and containers due to human negligence.

Contaminated Soil – we are denuding our soil from fertile to infertile. The indiscriminate use of chemically laced fertilizers, insecticides, pesticides to tend crops, actually contaminates the soil. Unprocessed garbage and sewage encroach upon unoccupied land making it dumping bin in sprawling cities. The green belts are the only grazing grounds left for animals. Drilling, digging and mining all chisel the layers of minerals and granite emptying the soil and leaving the rocky hills, lifeless and corroded. All these factors render the land useless for planting and cropping. Unsystematic, inorganic farming practices leave the soil unsustainable for growing.

Nuclear radiation

The potentially disastrous threat to the environment is from nuclear radiation, termed as the nuclear holocaust. Chernobyl, Russia and the Bhopal, India gas tragedy are succinct examples of what it will lead to and how the world will end up being.

Conclusion

All the causes of pollution are mostly man-made. We will have to reverse from hammering on nature and reserve back whatever little we can from our remaining resources. We will succeed if we willingly or by duress remove those causes that cause environment to degrade and pollute...
