Which countries pollute the most and who is being affected?

Three areas of the world, that is, United States of America, European Union and China account for 50% pollution in the world. 150 plus other countries account for the other 50%.

Looking at the Carbon Dioxide contribution in tonnes per year, out of the World total of 27 million tonnes, USA contributes 6 million tonnes, China and Taiwan 5 million tonnes and European Union contributes 4 million tonnes. (According to WikiAnswers)

China is also a major pollutant because of its use of cheap fuel like coal. Although such sources are cheap but are extremely harmful for the environment.

According to the same source, China leads in the overall pollution in the world. But I believe, USA follows close by. Even in Ocean pollution, China is leading at present.

According to the United Nations, nearly 5,500 people die everyday as a result of consuming polluted water and food. Nearly one sixth of the people in the world do not have access to clean drinking water and 2.4 billion people do not even have access to a proper latrine.

The greatest killer of children in the world is respiratory infections while the second most killer is diarrhea which takes away 2 million children every year. Other diseases are cholera, typhoid and polio.

What has been the use of all the developments in the world if it is killing people so cruelly? With all the inventions, we are unable to provide a safe haven for the children of the world. Its heart breaking when we hear that children die of pollution and its more distressing when we hear that people in Africa die because they have no food and water.
