BP has dumped about 160,000 gallons of Corexit – chemical dispersant made by the Nalco Company - in the Gulf (as well as pumping 6,000 gallons more all the way down to the leak location). The dispersant particles bind to oil, sink, and are carried away by ocean currents. But while that could help keep a spill from reaching the shores en masse, it means the oil isn’t actually “cleaned up,” but rather diluted. And the dispersant chemicals themselves can be dangerous. Nalco’s own documents go into detail about compounds that must be handled with great care in their original form, that should not touch the skin and can damage lungs.

Top: Gulf oil spill: giant containment box towed to site. BP tows a huge dome into the Gulf of Mexico, but it is far from certain whether it can stop the oil gushing from the seafloor.Efforts on Wednesday to contain the Gulf of Mexico oil spill centered on a towering metal box the size of a four-story building that engineering teams hope will corral the crude that continues to spout from the seafloor. Bottom: Oil from the massive Deepwater Horizon spill is seen on the surface of the water in Breton and Chandeleur Sound, off the Louisiana coast.  read more »

Top: "Large Air Spill at Wind Farm. No threats reported. Some claim to enjoy the breeze.". Bottom: in Gulf of Mexico, Deepwater Horizon oil rig explodes, burns, sinks (2 days later on Earth Day).

Gulf Oil Spill: ~210,000 gallons of oil leaking per day.

Fin whale, the 2nd largest mammal on earth: size comparison against an average human. Scientists calculate that 2,039,621 whales were killed in Antarctica's Southern Ocean during the decades of industrial whaling, including roughly three quarters of a million fin whale.

Top L: In 2006, Iceland killed the endangered fin whale for the 1st time since the 1980s. Top R & Bottom R: free & imprisoned Pete Bethune, skipper of Ady Gil / Earthrace.

Captain Paul Watson leads Sea Shepherd, volunteers & ocean guardians, spending 8 months per year at sea, fighting illegal whalers, sealers, and shark and dolphin fishermen. The latest Sea Shepherd Whale Defense campaign cut Japan whalers’ quota in half & saved 528 whales. 750,000 fin whales, the 2nd largest creature, were killed in the S. Hemisphere alone between 1904-79, & less than 3,000 currently remain. IWC's compromise would legalize commercial whaling. The endangered fin whale would continue to be a target.  read more »

Avatar director James Cameron played a part in halting an industrial development project that threatens indigenous people of the Amazon.

The Avatar director and one of its stars have played a part in halting an industrial development project that threatens indigenous people of the Amazon. Earlier this week, we brought you the story of James Cameron and Sigourney Weaver's trip to Brazil to raise awareness of the indigenous communities’ battles to stop the massive Belo Monte Dam on the Xingu River in the Amazon rainforest. We are now happy to report that the Dam Project Auctions have been canceled, and both stars are now in Washington DC for meetings with US Government officials.

Judge Antonio Carlos de Almeida Campelo granted a preliminary injunction (urgent) seeing “danger of irreparable harm” considering the imminence of the auction. The decision is the result of the assessment of one of two public civil actions filed by federal prosecutors dealing with irregularities of the enterprise. It focuses specifically on the lack of regulation of Article 176 of the Federal Constitution of Brazil, which requires the issuing of an ordinary law for the use of hydraulic potential on Indian lands.  read more »

The Economist magazine calls CITES suppress- ion of debate on bluefin tuna dis- honorable: IT WAS a moment of some drama when delegates assembled in Doha came to vote on a ban in the trade in bluefin tuna on March 18th. The previous evening many represent- atives of the 175 member nations of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) had been at a reception at the Japanese embassy. Prominent on the menu was bluefin tuna sushi. On the agenda the next day at the CITES meeting was a proposal to list the bluefin tuna as sufficiently endangered that it would qualify for a complete ban in the trade of the species (The Economist supports such a ban).  read more »

The battle to save some of the world’s most endangered species is turning bloody, with wildlife charities deploying guns and military vehicles to protect elephants, rhinos and tigers from a surge in poaching. "We have to keep talking but so far, against a backdrop of catastrophic population declines of key species, there is little to show for it,” said Dominic Dyer, chairman of CWI. “These animals are being wiped out by poachers who are increasingly well equipped with automatic weapons, GPS satellites, night-vision kit and heat-seeking telescopes to spot animals at night. That means we also need a more robust approach to enforcement."

At least one British organisation, Care for the Wild International (CWI), is buying military-style field equipment and supporting the deployment of armed guards, while the US-based International Fund for Animal Welfare (IFAW) has bought night-vision supplies, ammunition and light aircraft.

WWF, formerly known as the World Wildlife Fund, has hired former SAS soldiers to train African wildlife wardens, and the Zoological Society of London is funding elephant-mounted patrols to protect rhinos in Nepal. The trend towards militarisation follows an estimated 150 deaths among game wardens in Africa in gunfights with poachers.

The disclosures coincide with a meeting of the Convention on International Trade in Endangered Species in Qatar, which has dismissed proposals to protect bluefin tuna, and this week likely to approve plans to restart sales of ivory taken from African elephants.  read more »
