I am less pleased with the chapters on effects of environmental exposures of humans to pollutants and on economic effects of coastal pollution but it is too late and I am too tired now to begin patching. What you see is what you get. However in this concluding chapter I do want to revisit fleetingly most of the principal topics covered in the chapters and in rough order of their appearance in the book.
