Causes Of Land Pollution

By Roy Pernell

So what is land pollution really all about? The following report includes some fascinating information about the causes of land pollution--info you can use, not just the old stuff they used to tell you.

Pollution is one of the signs that humans have exceeded those limits. Pollution is a big problem for plants. For example, Pesticides are designed to allow farmers to increase their yields (and gardeners to keep out weeds), but their misuse and over-application can adversely affect any wild plants in the area. Water pollution events like oil spills or the accidental release of raw sewage can harm the environment. These events can kill fish and other water life and can threaten human health.

Pollution became a popular issue after WW2, when the aftermath of atomic warfare and testing made evident the perils of radioactive fallout. Then a conventional catastrophic event The Great Smog of 1952 in London killed at least 8000 people. Pollution is the contamination of water, air, and soil by substances harmful to life. It can occur naturally such as gases from volcanic eruptions that pollute the air. Pollution is caused by various industrial and agricultural processes, population growth and movement, and transportation. For thousands of years, people lived off the land without permanently harming it.

So far, we've uncovered some interesting facts about the causes of land pollution. You may decide that the following information is even more interesting.

Acid rain is another long-range pollutant influenced by vehicle NOx emissions. In all except worst-case situations, industrial and domestic pollutant sources, together with their impact on air quality, tend to be steady-state or improving over time. Acid air happens during modern smog when NO2 and SO2 are converted into acids; particularly nitric and sulphuric acid. These form into tiny clouds of acid droplets.

Carbon dioxide emission levels are not affected by the Zemission technology, but as with other types of combustion, use of biofuels can make the process carbon neutral. Carbon taxes are being put on gasoline up to $15 per gallon in some developed countries. There is still imbalance with this since worldwide subsidy to fossil is still over 700 billion while insignificant to renewables, (we (the world) have to pay the real cost of fossil, and I mean the health, environmental and climate change costs).

Most oil pollution is accidental but some is deliberate, such as ships illegally washing out their tanks at sea. Oil water logs a bird's feathers so that it drowns, dies of cold or is poisoned by swallowing oil when trying to clean its plumage. Oil-covered seas look calm, but if a bird land in a slick, the oil coats its feathers, affects its buoyancy and the insulating power of its feathers and makes it unable to fly away. Even slightly oiled birds sometimes die because they preen their feathers, and in doing so, ingest oily substances which are poisonous to them.

Knowing enough about the causes of land pollution to make solid, informed choices cuts down on the fear factor. If you apply what you've just learned about land pollution, you should have nothing to worry about.
