Many of the 'pollution' problems of previous decades seem to be 'solved', in the developed World, or at least managed to minimise their environmental impacts. Whilst pollutants such as sewage can now be treated to reduce their damaging qualities the resulting effluent still contains a potent mixture of compounds that negatively impact marine ecosystems. These include 'traditional' pollutants, such as metals, and 'new' ones such as hormone mimics and pharmaceutical residues. Similarly, although oil spills are now less common and better managed the growth in global trade means vast volumes of...
