Often we worry about our fresh water drinking quality due to pollution and contaminates. We know it is critical to have clean water in our civilization. We also know that it is important that our shorelines and oceans are clean, as it affects the eco-system, food chain and our local and regional sea life. We must worry about industry, sewer treatment plants, non-point source discharges to storm drains as well as the fertilizers, chemicals and debris which runs off into our water supplies and/or flows to the ocean.

We must pit these needs of our civilization against the environmental costs associated with them. We indeed cannot afford to make trades, which might cause dead zones of sea life or pollute our oceans. Luckily for us Mother Nature is quite resilient in handling mankind
