Pollution refers to the process of making land, water and air dirty and makes it not safe and suitable to use. With the increase in world population the pollution is increasing day by day at an alarming pace. Pollution can mainly be divided into three types: air pollution, water pollution, and soil pollution. We are going to discuss them with the problems associated with them.

Air pollution air is composed mainly of Carbon dioxide, Nitrogen, and Oxygen. About 99% of the air is made of nitrogen, oxygen and inert gases. Air pollution occurs when the composition of the air is disturbed by adding different things to it which not normally there. Common type of them is that particle which happens as a result of burning the fuel and those particles goes up in the air causing air pollution.

Another common type of air pollution is because of dangerous gases such carbon monoxide, CFC (chloral flora carbon), Sulfur dioxide, Nitrogen oxide and other chemical vapors.

CFC which is usually present in the compressor of the refrigerator is mainly responsible for the depletion of ozone layer. Ozone layer is made of O 3 and whenever the CFC goes up a reaction takes place between O 3 and CFC which break the layer of O 3 causing its depletion. Now this has a very dangerous effect on humans it causes skin diseases and many other such problems, because harmful rays from sun directly strike the human body. A recent study has shown that about 2 million people died each year because of air pollution. This amount is very alarming.

Soil pollution or land pollution is referring to the condition when garbage’s and industrial wastes are thrown without proper recycling. According to ENVIRONMENTAL PROTECTION AGENCY American produces about 250 tons of garbage and only 34% of which is recycled and the remaining are left for landfill. Especially in the developing countries where there is no proper system for disposal of wastes it really causes life threatening diseases e.g. measles and diarrhea. Leaving garbage on the land are very helpful in the spread of bacteria, virus, and fungi causing many diseases. Garbage must be handled properly by recycling them in order to protect the land from getting polluted.

Water pollution occurs when different materials from different sources are added or entered into water such as different chemicals, sewage, certain metals like lead and mercury; fertilizers from agriculture runoff and are the main contributing factors of water pollution. Water pollution is a worldwide problem. According to the United Nations, 783 million people do not have access to clean water, and around 2.5 billion people do not have proper sanitation. This amount of pollution severely effects marine life. Water is very necessary for life. Life cannot exist without water. The human body consists of 70% water. Knowing this important information we realize water must not be polluted because polluted water causes a lot of diseases, such as diarrhea, constipation. Polluted water will not just causes human diseases, but it also makes life difficult for marine life.
