Backyard Aquaponics
A place to discuss aquaponics

My understanding was that the inversion layer created by carbon dioxide, methane and other greenhouse gas pollutants, thus trapping the heat in the earth's atmosphere.... was largely responsible for warming...

Clear, clean air... IMO... is the solution to the problem...

Crave Man
David Kessler Knew That Some Foods Are Hard to Resist; Now He Knows Why

He went in the middle of the night, long after the last employee had locked up the Chili's Grill and Bar. He'd steer his car around the back, check to make sure no one was around and then quietly approach the dumpster.

If anyone noticed the man foraging through the trash, they would have assumed he was a vagrant. Except he was wearing black dress slacks and padded gardening gloves. "I'm surprised he didn't wear a tie," his wife said dryly.

The high-octane career path of David A. Kessler, the Harvard-trained doctor, lawyer, medical school dean and former commissioner of the Food and Drug Administration had come to this: nocturnal dumpster diving. Sometimes, he would just reach in. Other times, he would climb in.
......

It took many of these forays until Kessler emerged with his prize: ingredient labels affixed to empty cardboard boxes that spelled out the fats, salt and sugar used to make the Southwestern Eggrolls, Boneless Shanghai Wings and other dishes served by the nation's second-largest restaurant chain.

Kessler was on a mission to understand a problem that has vexed him since childhood: why he can't resist certain foods.

His resulting theory, described in his new book, "The End of Overeating," is startling. Foods high in fat, salt and sugar alter the brain's chemistry in ways that compel people to overeat. "Much of the scientific research around overeating has been physiology -- what's going on in our body," he said. "The real question is what's going on in our brain."

.....

The labels showed the foods were bathed in salt, fat and sugars, beyond what a diner might expect by reading the menu, Kessler said. The ingredient list for Southwestern Eggrolls mentioned salt eight different times; sugars showed up five times. The "egg rolls," which are deep-fried in fat, contain chicken that has been chopped up like meatloaf to give it a "melt in the mouth" quality that also makes it faster to eat. By the time a diner has finished this appetizer, she has consumed 910 calories, 57 grams of fat and 1,960 milligrams of sodium.

Instead of satisfying hunger, the salt-fat-sugar combination will stimulate that diner's brain to crave more, Kessler said. For many, the come-on offered by Lay's Potato Chips -- "Betcha can't eat just one" -- is scientifically accurate. And the food industry manipulates this neurological response, designing foods to induce people to eat more than they should or even want, Kessler found.

.....

"The challenge is how do we explain to America what's going on -- how do we break through and help people understand how their brains have been captured?" he said.

.....

Whether government ought to exercise tougher controls over the food industry is going to be the next great debate, especially since much of the advertising is aimed at children, Kessler said.

"The food the industry is selling is much more powerful than we realized," he said. "I used to think I ate to feel full. Now I know, we have the science that shows, we're eating to stimulate ourselves. And so the question is what are we going to do about it?"

....

"Highly palatable" foods -- those containing fat, sugar and salt -- stimulate the brain to release dopamine, the neurotransmitter associated with the pleasure center, he found. In time, the brain gets wired so that dopamine pathways light up at the mere suggestion of the food, such as driving past a fast-food restaurant, and the urge to eat the food grows insistent. Once the food is eaten, the brain releases opioids, which bring emotional relief. Together, dopamine and opioids create a pathway that can activate every time a person is reminded about the particular food. This happens regardless of whether the person is hungry.

Not everyone is vulnerable to "conditioned overeating" -- Kessler estimates that about 15 percent of the population is not affected and says more research is needed to understand what makes them immune. .............

does this or will this eventually change the weight of the earth and thus its oribit??

Ummm...the info I've found says that while the last couple years were a bit cooler, something like 7 of the hottest years in history were in the last ten years. And Pinatubo put out something like 42Mtons to 350Mtons during it's eruption, compared to 70Mtons per day, 25billion tons per year for humans. There are some widely and happily quoted errors out there that do not help with an accurate debate. Too bad we don't have folks who both sides see as honestly vetting information rather than having trusted folks (on either side) who are happy to use errors, exaggerations, or lies to advance their arguments.
