All unnatural material that finds its way to the world’s seas is classified as ocean pollution‚ however these materials built up over time. This process is known as bioaccumulation. There are many contributing pollutants to bioaccumulation in oceans such as toxins‚ marine debris‚ oil‚ sewage‚ eroded soil‚ and heavy metals. In the past‚ dumping small amounts of pollutants into the oceans‚ known as dilution‚ was not thought of to be a threat to the environment because all of the oceans combined

Magnetohydrodynamic drive In concept‚ MHD is attractive because it offers a propulsion system that requires no moving parts. It works on a principle similar to that of an electric motor or generator; that is‚ passing an electrical current through a magnetic field creates a force. In an MHD propulsion system‚ a magnetic field is created within the hull‚ and sea water is used to conduct the electric current‚ as shown in the illustrations accompanying this story. The underlying principle is known
