Until recently, water pollution has been a relatively local problem of the developed world. Sea pollution may be defined as the presence in the sea of significant amounts of unnatural substances or abnormally high concentration of unnatural substances at a level that causes undesirable effects.
Such problems are increasingly occurring on a worldwide basis and affect marine as well as fresh ecosystems. Seriously polluted seas include the Irish Sea, the Dead Sea, the North Sea and others.
We may look at pollution in different ways according to the type of pollutant and degradable nature of pollutants. Certain products are invented with a major purpose or are of some economical advantage to man, but later when used are found to have serious side effects.
Some of these include synthetic detergents, pesticides and medicinal drugs. Some of these wastes are non-degradable or cannot be processed by nature within a reasonable period of time. They accumulate and pollute the seas. The nature of sea pollutants can be generalized in biodegradable and non-biodegradable pollutants. Biodegradable pollutants can be broken down by micro-organisms and hence, effectively removed after a long period of time from the water. Unfortunately the non-biodegradable pollutants cannot be removed and these are the ones that pose a danger to human life. Like air, water is a very important natural resource to organisms. Organisms need it when it's clean. However industries and excessive population have polluted our seas. Water is polluted if its quality is changed so that it becomes less suitable for drinking, domestic, agricultural and recreational purposes or other activities for which it is suitable in its natural state.
