'In the Pacific Ocean there is an area the size of Texas covered in plastic. We must curb our insatiable appetite for stuff, or at least re-evaluate how we produce that stuff.'
Philippe Cousteau, president of Earth Echo International in Washington; grandson of ocean explorer Jacques Cousteau
While there is uncertainty about the impact of plastic in the marine environment, 'If there was ever a case that could be made for the so-called precautionary principle, this should be one.'
Anthony Andrady, senior scientist at Research Triangle Institute, Research Triangle Park, N.C.
