Eat a salad, save the planet?
That appears to be the case. Biologists at the London School of Hygiene and Tropical Medicine (odd combo … ) have determined that all of humanity weighs 287 million tons. For some reason, the biologists didn’t include children in their calculation, so this number is actually larger.
And of the 287 million tons adult earthlings weigh, it turns out 15 million tons of this is extra fat. North America is the most overweight (big surprise); we have 6 percent of the global population but account for 7.4 percent of human “biomass.” In fact, a full third of ALL global obesity resides in North America. If our “fatness” was spread across the entire global population, it would be the equivalent of an extra 473 million humans of average weight.
Putting the numbers another way, the average North American weighs 178 pounds while the global average is 137 pounds and Asians average just 127 pounds. How does us being overweight affect global warming? Actually more than you might think.
Our fat cells need to be fed with processed foods and large servings of meat mostly. Production of these food resources uses more energy than that salad I mentioned at the start. On top of that, heavier people require more energy to move around. Trains, planes, and automobiles expend more energy moving heavier loads and, yes, a car full of overweight individuals burns more gas than a car full of people with normal BMIs. (Here’s a collection of my “This is Why You’re Fat” posts.)
So on top of all the other reasons why we should lose weight, let’s add global warming to the list. You’ll look better, you’ll feel better, and you’ll save the planet.
Pass me a carrot please …
