Water pollution
We have many natural resources but water is the most important of
them. However most of the time we don’t take care of it. We waste
a lot of water; also we pollute it with different substances. For
example, at home we use soap powdered that often contains
chemicals with non-biodegradable molecules; this means that the
molecules don’t break down naturally, so they will stay in the water
indefinitely building up the toxic levels. People use other substances
at home that are very toxic for water and for the human being. This
toxic water goes to the rivers, lakes or oceans and it affects marine
creatures. Oceans are polluted from oil spills, too. Pollution in the
oceans is a big problem that directly affects ocean organisms. So,
oceans are the mayor carriers of pollutants because they spread
rapidly and travel all over the world via inter-connected seas.
