As a result of environmentalists' efforts, people are more aware of the pollution they cause in the air, water and on the surface of the ground. Water pollution in particular, has been increasing over the last decades which raised the questions of what the reasons are, in what ways it affects our lives and how can we get rid of it. Although the awareness has helped us educate our children and build more environmentally friendly materials which we use in our ships and submarines, we still are considered a threat to the living things inside the oceans and seas due to all the industrial waste we release into the water, the trash we carelessly throw out of our boats and the huge oil spillage we witness every now and then.
