I just read in the latest issue of Men's Health magazine the first of its kind study, on a pretty major, negative impact that climate change is having on the worlds health in general, and its weight, in specific.
It seems weight, both human and animal, of all kinds, is up all over the world, in places even in remote villages in China it appears. A Ph.D. at the University of Alabama recently did some studies and ran some tests on some volunteer patients to find the answer. His results are as follows: we all know that carbon dioxide levels are now at a place around 400 or so ppm, a place where they have not been for millions of years. Before life even. Turns out we are all breathing in this extra Co2, of course, and it looks like this is making our blood more acidic, and this in turn affects certain cells in the brain. Sometime in the 90's these cells in the brain were discovered that deal with hunger.
This higher level of CO2 is stimulating these cells in the brain, which in turn is stimulating the appetites of both humans, and animals it appears.
So if it seems like you are trying harder than ever, to lose, and you are finding it very difficult, or it may be a losing battle, you can thank climate change. It just makes me wonder what other damage is being done to our bodies.
