Pollution is anything that is present or introduced into an environment which causes harm. In the sea there are many kinds of pollution such as rubbish, oil, chemicals and even sewage from toilets!
In the last ten years the waters have borne the brunt of serious pollution accidents, but these are becoming less common as technologies develop and the affects become better understood. But, there is still an awful lot to learn about the effects of polluting marine environments. Often the pollution cannot be seen by the naked eye, and sometimes pollution will never disappear from the water.
In many ways it is humans' own actions that lead to pollution and in some cases we can do something about it. For example, buying local products reduces the demand for food from overseas, reducing the amount of ships needed to carry this food, and in turn reducing the pollution they cause on the oceans and the waste they dispose of.
