When the earth came into the existence the pollutants were very few. The amount of pollution  has increased due to the increase in population and decrease in the natural resources. Their rates have increased many folds and have an adverse effect on the human health. It also leads to the financial losses. Basically  pollution  is defined as an unwanted  change  in the  environment  which involves the  physical , biological and  chemical changes  involving air, water and land which affects the human life in one way or the other. It also affects the natural resources, living conditions and the cultural aspects of the humans. It can  be natural  or manmade. The natural  pollution  comes from the natural gas,  volcano eruptions , soil erosions and cosmic rays. The natural  pollution  is less in concentration as compared to the manmade  pollution . In the contamination there occur harmful organisms which cause the disease.

Pollution is when something is added to the environment that is harmful or poisonous to living things. Smoke in the air from factories is a type of pollution as it is bad for the lungs when breathed in. Sewage in drinking water is another type of pollution, as it can make people ill because it contains germs and viruses. People living next to a building site where there is too much noise can become sick as they cannot sleep or relax.

Pollution is a serious issue affecting our planet today, yet many people continue to turn a blind eye thinking that its not that serious.

Pollution as is described is the addition of substances to the environment faster that the environment can dispose, recycle, decompose, or store in a harmless state.

There are different types of pollution and includes water, soil, air, and sound pollution and all these continue to cause major problems. In our quest to better, our lives we forget or rather ignore the negative impacts such deeds can have on the environment.

Mostly the cities where there is a lot of population are most affected. The fumes that emanate from factories and vehicles not only make it difficult to breathe but affects the ozone layer. The garbage, honking, blaring music are all menaces that we should aim to reduce for a better planet

The biggest paradox is that the more we pollute the environment the riskier it becomes for us to live in it. Pollution affects our health, which lowers our quality of life significantly.

Poisonous chemicals emitted in factories are dangerous and exposes us to various elements that cause cancer. Garbage scattered all over increases the chance of us getting a variety of epidemic diseases.

The major problem brought about by pollution is global warming which has resulted to changes in the global climate patterns. We can no longer predict on what to expect on the different seasons unlike before. Things are so bad that life on earth in general is under great risk

According to scientists, its not too late to take action we can take measures to prevent any further damage and adopt better waste disposal measures for a better planet.

Each one of us needs to be responsible in protecting the environment. We can all do things better to ensure we safeguard our human race for our benefit and our future generations. Simple things such as saving electricity, fuel, using biodegradable materials, recycling, among others count in reducing pollution.

We should all aim to better our planet by the simple things we do. Take action now.
