The Main Types of Pollution on the Earth and the Promise of Renewable Energy

The Main Types of Pollution on the Earth and the Promise of Renewable Energy
Page content


The pledge of renewable energy has continued to be a major part of controversy. Proponents argue that reasonable, extensive use of renewables in addition to accurate preservation guidelines can meet World energy necessities in the near future. The lone obstruction is said to be that the energy organizations and governments are not attempting hard enough to build up the inexpensive, non-polluting, and tremendous power sources that are out there, in the offing, to be exploited. On the other hand, agnostics of the extensive usefulness of renewables point to their still microscopic involvement as energy sources.

Renewables at present add little to the complete energy supply in the US- when taken as a portion of the total energy utilization. The primary reasons for difference are the consequences of enduring droughts (in the southwest) and depending on hydropower, which is the prime renewable energy generator in America. Nevertheless, this is simply one feature of the matter. Some renewable sources, like biomass, are starting to make noteworthy shares to energy provisions in quite a few urbanized nations, and this includes the US as well.

Photovoltaic cells are cost-effectively feasible in some conditions even now, and wind power, which still forms a minuscule part of the energy combine, are speedily booming in the United States and in quite a lot of European countries as well.

At this point we are posed with a query and that is whether the swift spreading out of these sources throughout the past decade places us ahead of time on the growing slant of the “S” arc thus connoting more speedy development in the future. Or, are we nearing a tableland, with the out-and-out worth of renewable energy output not expected to augment significantly for several decades still?

Land, Water, and Air pollution

Land pollution is, without an iota of doubt, ruining our fertile lands. It is principally about polluting the Earth’s surface by throwing away urban waste matter at random, discarding manufacturing waste, misusing minerals, and perverting the soil by injurious agricultural uses. Land pollution is also noticeable in the sheer amounts of debris and waste, besides the soil itself being contaminated. The soil is contaminated from the chemicals in insect killers and weed killers applied for agricultural uses along with waste substances found cluttering urban regions like roads, parks, and streets.

Air pollution on the other hand may even threaten our food supply. Based on a new report by University of Virginia researchers, air contamination from power plants and autos is ruining the scent of flowers and thus subduing the capability of pollinating insects to pursue scent tracks to their source. Jose D. Fuentes, a professor of environmental sciences at the University of Virginia and a co-author of the study stated thus: “The scent molecules produced by flowers in a less polluted environment, such as in the 1800s, could travel for roughly 1,000 to 1,200 meters; but in today’s polluted environment downwind of major cities, they may travel only 200 to 300 meters. This makes it increasingly difficult for pollinators to locate the flowers.”

With regard to water pollution the wastes from industries and factories have actually to a large extent reduced in recent years. The main sources of water pollution now are excess water from washing cars, manure from farms and gardens, and pet droppings.

Health Effects of Pollution

Renewable Sources and Its Viability

In numerous areas, the view for inexhaustible energy may be promising. The stance for important development in hydroelectricity or geothermal electricity does not look great, but the usage of biomass, solar electricity, and wind establish promise for improved use. Presently, only wind looks to be in a phase of speedy growth, principally because it is cost-effectively the most viable in a country and perhaps because it has succeeded in capturing the public imagination.

There is little incongruity that if inexhaustible sources of energy were to establish strictly practical and reasonably practicable in the quantities demanded, they would be significantly preferred to present means of energy production.

Everybody is a stakeholder since all of us are dwellers of this one and lone mother earth. So everyone can contribute towards making this earth pollution free and also create awareness among those people who are not bothered or do not care. When we protect the environment, it means that we love and care for our children by assuring a sustainable future for generations to come.

You and I should consequently acknowledge personal liability for the accomplishment of the environmental protection programs of our particular community by collaborating and enthusiastically taking part in making the ambiance pollution free. Although in isolation we can lend a hand to scrap pollution in our own direct environment, competent control can be best committed through statute law. Thus, nearly all countries have by now turned to the issue by passing some type of pollution avoidance measures.

Costs of Checking Pollution and Environmental Ordinances

Pollution control technology is oftentimes costly. Actually these measures or regulations do not give rise to any benefit either to production quantity or the quality of the products. Hence, checking pollution increases production costs, which in turn decrease the overall profits. This is the reason why governments in most countries do not want to interfere with environmental ordinances- until environmental crisis leads to action being taken without any delay. In addition, particularly in deprived, poorly regularized countries, those accountable for inducing most of the ecology harm are part of the home economic and political privileged, and are therefore without difficulty competent at obstructing any standards they see as opposing their concerns.


Preventing the onset of contamination in any part, be it on air, water or land, could mark the beginning of a simplest precautionary key to the crisis. This calls for a meticulous attempt to assume excellent practices or customs by the people, the enactment and the appropriate execution of proper government policies and the stern observance particularly by possible industrial wastes.

If pollutants are not there, then it is natural that there will be no pollution. But still stating this is easier than doing it. Some horrific practices are deep-rooted and industrial growth in some way contributes to the simultaneous troubles of pollution. The price tag to business and its viable complications make this relatively simple precautionary advance reasonably complex and trickier to put into practice.
