Pollution

Introduction

There are two types of the cause of pollution, natural and man-made. Natural pollution occurs naturally and won't cause excessive harm to our lives due to its regeneration ability. While the man-made pollution is caused by human activities, and hard to get rid of. The backbones of man-made pollution are human population and technology. Naturally human needs contact to the environment, we get resources from nature. This is for the sake of living. By the increase of human population, the contact is getting more intensive, because needs are increasing. And by the findings and development of new technologies, human can apply them to get the resources. And it's common that new technologies would bring their respective side effects besides their advantages.

Small population with any level of technology wouldn't have to exploit the nature overwhelmingly. But big population with any level of technology will surely exploit the nature more, and even overwhelmingly, this is all for the needs of the people.

Pollution is a growing pain. Pollution is not a problem that came suddenly from the sky; it's our fault and has been a part of our life through many years. We must be wise in managing our resources, and take positive action towards preventing any forms of pollution to the environment. Make the world a better place to live.
There are 6 (six) types of pollution that are going to be discussed in this site, namely air, water, noise, land, radioactive, and thermal.

Definition
Presence of matter (gas, liquid, solid) or energy (heat, noise, radiation) whose nature, location, or quantity directly or indirectly alters characteristics or processes of any part of the environment, and causes (or has the potential to cause) damage to the condition, health, safety, or welfare of animals, humans, plants, or property.

Pollution is the introduction of contaminants into an environment that causes instability, disorder, harm or discomfort to the ecosystem i.e. physical systems or living organisms. Pollution can take the form of chemical substances, or energy, such as noise, heat, or light energy. Pollutants, the elements of pollution, can be foreign substances or energies, or naturally occurring; when naturally occurring, they are considered contaminants when they exceed natural levels. Pollution is often classed as point source or nonpoint source pollution.

The pollution in developing countries has always been reported high in comparison to developed countries. Our developing country, India, is also enclosed in a thick layer of pollution because of rapid industrial development, transport explosion, unconditional management of natural resources and fast growth of towns and cities, among others. Owing to all these factors, the pollution level in India has been rising on an everyday basis and is increasing manifold.

The pollution in India is not only fouling all the natural resources of our country but is also the main culprit behind the increasing health problems that the people of the country face today. Pollution in all its forms – noise pollution, air pollution, water pollution, sound pollution, soil pollution – is hazardous and is bound to leave long-lasting effects.

Many people raise debates on the advantages that industrialization and modernization have derived. No doubt, with more facilities and companies available in the country, the number of employment opportunities has increased. There has been major change in the lifestyle of majority of people in the country. However, unorganized growth of cities, villages and towns has, unknowingly, favored the growth of unhealthy environment.

With industrialization and infrastructure development at its peaks in many metropolitan cities of the country, the pollution in India has made it difficult for people in these cities breathe fresh and clean air. The smoke emitted from a large number of vehicles on the road has formed a thick blanket very close to the lowermost layer of the atmosphere, which in turn has completely cut the flush of fresh air. Adding to this is the smoke emitted from the high-rising chimneys of many factories. This smoke not only adds to havoc in the lives of the people of the concerned city, they also leave an adverse affect on the agriculture in the nearby areas.

Agricultural menace also arises from the number of insecticides and pesticides that are used for the fruits and vegetables to mature well before their maturity period. A large number of manures and chemical fertilizers are also used now-a-days which first destroy the complete nutritional value of the food items and once the crop is harvested, the ill-effect is passed on to the soil. This is how it is passed on to crop after crop.

Some other dangerous pollutants to the atmosphere other than the smoke from vehicles and factories are fluorides, radioactive fallouts and nuclear energy programme, among others. Among all this, pollution of water, the most important substance for human existence, is of utmost importance. Liquid wastes from industries and houses blindly flow into the open water bodies and this poses serious threat to the animal and plant life that resides in water. Depletion of huge forest cover in the form of forests has also been a serious kind of land pollution in terms of deforestation.

Therefore, it is very important that all of us understand the importance of our resources being pure for ourselves and our future generation live a healthy happy life. Although the government of India has passed out many laws to make sure that our resources are pollution free, it is the responsibility of each citizen to look into this matter seriously and do every small bit that can serve this main big cause.
