Pollution

Clouds of choking smog; beaches coated in oil; rivers turned red by chemicals. All of these are obvious examples of pollution.

However, not all types of pollution are easily seen. For example, invisible plumes of gas may drift over our towns and cities. They can cause asthma and chest problems. They can also kill trees.

Yet you're eating it and drinking it and breathing it most of the time. And what is worse is that it affects all other life on Earth. You can find pollution made by people just about everywhere on the planet. Even remote places like the Arctic are badly polluted by chemicals made by people.

The polar bears and seals there have poisonous chemicals made by people in their bodies and so do the Inuit people who live with them. These nasty things kill many animals and make others sick -- including penguins in the Antarctic. They also kill people and make them ill too. There's nowhere on the planet left with no pollution; not even the bottom of the sea or high up in the air.

But now that we know about it let's be positive, since we know how we can make things better.
