Over 50 percent of the population in the United States and over 60 percent in the world live in coastal areas. Rapidly growing human populations near the ocean have massively altered coastal water ecosystems.

One of the most extensive human stressors is the discharge of chemicals and pollutants into the ocean. In the Southern California Bight, more than 60 sewage and urban runoff sources discharge over 1 billion gallons of liquid on a dry day with the two largest sources of contaminants being sewage from municipal treatment plants and urban runoff from highly modified river basins.

GAINESVILLE, Fla. — Twenty years after biologists attempted to determine the ecological damages to marine life from the Exxon Valdez oil spill, scientists dealing with the BP disaster find themselves with the same problem: the lack of critical data to determine the ecological consequences of human-induced environmental disasters, a University of Florida researcher said.

Fighting ‘Global Warming’ but not the wrong way

Global atmospheric carbon dioxide (CO₂) concentration has increased from a pre-industrial value of about 280 ppm to 379 ppm in 2005. CO₂ is a greenhouse gas. It traps the sun rays in the atmosphere that should in other way reflect back to the space. But as the rays are trapped, the atmospheric temperature increases – ‘global warming’.
