Effects of pollution on earth essay

We provide high-quality, trusted science for cleaner air and better health. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. So what is it? A classic example of a primary pollutant would be the sulfur-dioxide emitted from factoriesSecondary pollutants are the ones that are caused by the inter mingling and reactions of primary pollutants. We breathe in every polluted particle from the air result is increase in asthma and cancer in the lungs. In practice, about ten different substances cause most concern: Now let's look a bit more closely at the three key sources of air pollution.

7)Pollution is the addition of any substance or form of energy (e. Theoretically, that means there are dozens of different pollution gases. It is revised and updated every year.

With modernization and development in our lives pollution has reached its peak giving rise to global warming and human illness. Every form of pollution has two sources of occurrence the point and the non-point sources. We hear about the various forms of and read about it through the mass media. If you suspect that nearby water sources have been contaminated by a corporation then it might be a good idea to hire an expert to see your options. Photo: Brown smog lingers over Denver, Colorado.

8) Release of sulphur dioxide and hazardous gases into the air causes global warming and acid rain which in turn have increased temperatures, erratic rains and droughts worldwide making it tough for the animals to survive. Pollutants can be naturally occurring substances or energies, but are considered contaminants when in excess of natural levels. Any gas could qualify as pollution if it reached a high enough concentration to do harm. Pollutants are the key elements or components of pollution which are generally waste materials of different forms. Pollution disturbs our ecosystem and the balance in the environment. Has taken toll of all the surviving species of the earth. , a direct result of the increased imbalance of gases in the atmosphere has come to be known as the biggest threat and challenge that the contemporary world has to overcome in a bid for survival. It occurs due to many reasons. Air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. We discuss major aspects of this study area, from definitions to pollution types sources as well as wide-ranging pollution effects.

Wherever possible, I've referenced my sources with links the following notes (indicated by bracketed numbers in the text) are mostly references to books, journals, and other offline reports that can't be linked the same way. Big particles can be between 7. G. Is the most prominent and dangerous form of pollution. Air pollution can further be classified into two sections- Visible air pollution and invisible air pollution. Created by the interactions of several primary pollutants is known to be as secondary pollutant. In order to get a better understanding of it, let s have a look at some common definitions. Fortunately, Earth is forgiving and damage from water pollution is often reversible. 6) Pollution is the introduction of contaminants into the environment that cause harm or discomfort to humans or other living organisms, or that damage the environment which can come in the form of chemical substances, or energy such as noise, heat or light.

Excessive burning of fuel which is a necessity of our daily lives for cooking, driving and other industrial activities releases a huge amount of chemical substances in the air everyday these pollute the air. Pollution occurs when pollutants contaminate the natural surroundings which brings about changes that affect our normal lifestyles adversely. You might like some of these other articles on Explain that Stuff covering related topics: The pollutants that are a direct result of the process can be called primary pollutants. Small particles are smaller than 7. The effects of air pollution are evident too. Photo by Warren Gretz courtesy of US DOE National Renewable Energy Laboratory (NREL). This article was originally written for the UK Rivers Network and first published on their website in April 7556. Pollution occurs in different forms air, water, soil, radioactive, noise, heat/ thermal and light. The sustainment of all things living is due to a combination of gases that collectively form the atmosphere the imbalance caused by the increase or decrease of the percentage of these gases can be harmful for survival.

Almost 65% of the species live in water bodies. In order to understand the causes of Air pollution, several divisions can be made. We are discussing the effects of air pollution and specific air pollutants in more detail in our article. The Ozone layer considered crucial for the existence of the ecosystems on the planet is depleting due to increased pollution. , heat, sound, radioactivity) to the environment at a rate faster than the environment can accommodate it by dispersion, breakdown, recycling, or storage in some harmless form. ( Ref. Experts admit that pollution effects are quite often underestimated and that more research is needed to understand the connections between pollution and its effects on all life forms. We know that pollution causes not only physical disabilities but also psychological and behavioral disorders in people. Effects of pollution on earth essay. All air, water and soil pollution have an impact on the living environment. It occurs due to several factors the industrial wastes dumped into the rivers and other water bodies cause an imbalance in the water leading to its severe contamination and death of aquatic species.

Smoke from chimneys, factories, vehicles or burning of wood basically occurs due to coal burning this releases sulphur dioxide into the air making it toxic. , extra or missing limbs in frogs. Photo courtesy of US Fish Wildlife Service Photo Library. The effects in living organisms may range from mild discomfort to serious diseases such as cancer to physical deformities ex. The point sources are easy to identify, monitor and control, whereas the non-point sources are hard to control. Primarily air pollutants can be caused by primary sources or secondary sources. Pollution, we hear it every other day at school, college and read about it in newspapers.  Let us discuss the different types of pollutions, their causes and effects on mankind and the as a whole. So what is pollution? Environmental pollution is the contamination of the physical and biological components of the earth/atmosphere system to such an extent that normal environmental processes are adversely affected. Pollution is now a common place term, that our ears are attuned to. It occurs when any harmful gases, dust, smoke enters into the atmosphere and makes it difficult for plants, animals and humans to survive as the air becomes dirty. Another way of looking at Air pollution could be any substance that holds the potential to hinder the atmosphere or the well being of the living beings surviving in it.
