The image of the woolly mammoth, saber-toothed cat and dodo bird stepping out of a beaker on the cover of National Geographic’s April issue says it all. Science has found a way to bring back some long-extinct species — or at least, facsimiles of them.
In truth, the goat-like bucardo, or Pyrenean ibex, is the only extinct animal scientists have actually revived. In 2003, biologists managed to clone an offspring from frozen skin cells from the last survivor, which died in 2000. The clone, however, lived for only a few minutes after its birth. Since then, advances in cloning technology have made it possible to bring back any species if there is a remnant of DNA.
But with so many habitat pressures on the wild species that are already here and with so many on the brink of extinction, is bringing back those we’ve already lost a good idea?
Did you know that the brain has the same chemical reaction to sugary and fatty foods as it does to cocaine or nicotine? According to Dr. Pam Peeke, author of The Hunger Fix, the chemical reaction happens before you even eat the food — all you have to do is think about it!
Dr. Peeke recently appeared on GaiamTV.com’s Gaiam Inspirations to talk about America’s food addiction and how to retrain your brain to make healthier choices. Dr. Peeke’s interest in the topic of food addiction started because of the way her patients talked about food. “I can’t get off this stuff.” “The withdrawal is killing me.” They sounded like drug addicts, and she started to wonder if there was a connection between food and addiction.
She found that there’s a very striking connection — and the same centers of the brain are involved that regulate drug addiction. And, she says, don’t think for a second the food industry hasn’t figured this out.
