Damage from Chemical Exposure Passed Down for Generations

New research has shown that exposure to commonly used chemicals causes changes in rats that are passed down through multiple generations.

“We are now in the third human generation since the start of the chemical revolution, since humans have been exposed to these kinds of toxins,” says David Crews, co-author of the study and a researcher at the University of Texas. “This is the animal model of that.”

“The ancestral exposure of your great grandmother alters your brain development to then respond to stress differently,” says Michael Skinner, co-author and a researcher at Washington State University. “We did not know a stress response could be programmed by your ancestors’ environmental exposures.”

Expert warns world needs to move ‘rapidly’ toward ‘population shrinkage’

The world’s most renowned population analyst has called for a massive reduction in the number of humans and for natural resources to be redistributed from the rich to the poor.

Paul Ehrlich, Bing professor of population studies at Stanford University in California and author of the best-selling Population Bomb book in 1968, goes much further than the Royal Society in London which this morning said that physical numbers were as important as the amount of natural resources consumed.

The optimum population of Earth – enough to guarantee the minimal physical ingredients of a decent life to everyone – was 1.5 to 2 billion people rather than the 7 billion who are alive today or the 9 billion expected in 2050, said Ehrlich in an interview with the Guardian.

An Arizona Tea Party-backed bill that would gut government-run green programs in the state may have the support it needs to go before Gov. Jan Brewer (R).

In a preliminary voice vote on Wednesday, the Arizona House approved a bill introduced by Tea Party member Rep. Judy Burges (R-Sun City West) with the stated goal of preventing “social engineering … including where we live, what we eat.”

Burges’ bill, Senate Bill 1507, targets a United Nations declaration promoting international environmental sustainability, which was adopted by the governments of 172 nations — including the United States under the George H. W. Bush Administration — in 1992. Conspiracy theories about the non-binding plan to foster environmental stewardship have long been entertained by conservative organizations such as the John Birch Society, which refers to the declaration as “Agenda 21.”

With mutant seafood devastating Gulf Coast fisheries, we are sending a picture of a mutant shrimp to Speaker John Boehner. We are including a petition telling Boehner to pass legislation mandating that fines paid by BP go toward the clean up and restoration of the Gulf Coast.

Earth Day: Would you buy a $60 energy-efficient light bulb?

Proponents of the new light bulb, which can reportedly last up to 10 years or more, say it will ultimately save consumers money because they won’t have to replace nearly as many light bulbs over time. The Washington Post suggests that the savings could top $100 over the course of a decade.

Philips says the bulb will also save plenty of energy: It consumes less than 10 watts to produce light that is the equivalent of a 60-watt incandescent bulb, saving 83% of energy in the process. The company says that if every household in the U.S. used the new bulbs instead of regular 60-watt bulbs, the nation could avoid 20 million metric tons of carbon emissions.

When BP’s Deepwater Horizon well exploded two years ago and spewed nearly 200 million gallons of Louisiana crude into one of the world’s most productive fisheries, people of the Gulf prayed it would be a fleeting disaster. It took BP nearly three months to plug the blowout, and despite assurances from government and industry scientists that a crisis largely had been averted, many fishermen and residents of the Gulf knew that was not the end of the oil.

Now two years later, many on the front lines of this disaster are still worried about their livelihoods and the future health of the Gulf fisheries—as well as the people exposed to the toxins that washed and blew ashore. BP used millions of gallons of chemical dispersant to break up the oil and drop it underwater, where many say it still lies, churned up with every storm and blown into the bayous and beaches with every strong south wind. New studies show the sticky tar balls are a potential threat to beachgoers and contain toxins like dangerous vibrio bacteria can poison fish consumers.

Meanwhile, dolphins continue to die in record numbers.



Stories from the Gulf Reveal BP Disaster Still Hurts

BP oil spill disaster ‘not over’Two years after BP oil spill, fishermen and scientists in the US Gulf Coast warn the disaster is not over.

Dead dolphins keep washing up on shore in unprecedented numbers. Oil-coated coral reefs are dying in the deepwater. Eyeless shrimp and crabs with holes in their shells are showing up in relatively empty fishing nets while killifish, a minnow-like fish at the base of the food chain, show signs of chemical poisoning.

And critics say offshore drilling safety and oversight remains woefully lacking.
