Toxic Dolphins Found in Miami

bottlenose dolphin

Scientists found unusually high levels of flame retardant in dolphin blubber.

The closer the dolphins lived to downtown Miami, the more of the chemical was concentrated in them. The flame retardant can cause sterility in dolphins. Brominated flame retardants are applied to furniture, clothes and electronics to prevent them from burning. They also help slow the ignition of items that are in a burning room.

Sewage Pipeline in the Pacific Spawns New Marine Life

Marine ReefAccording to a report in today’s Globe and Mail, a sewage pipeline installed by Epcor (www.epcor.ca) - a Canadian utility company – has created an artificial reef system that supports marine life in a previously desolate region.

Most people don’t associate outfalls with increased life, but this pipeline structure is adding complexity to what was a flat, sandy habitat,” said Jason Clarke, an engineer and marine biologist with consulting firm WorleyParsons. “It’s been a rapid diversification that I haven’t seen to quite this degree.

Oceans are Hurting: Thanks, Humans

Warmer shades indicate ocean areas most impacted by human activity. (Map courtesy of NOAA.)Most of Earth might be covered with water, but the large population of bipedal animals that crowd the planet’s land masses is doing its best to leave its imprint on the oceans as well.
