Question

When the world was a simpler place ,the rich were fat ,the poor were thin ,and right-thinking people worried about how to feed the hungry .Now ,in much of the world ,the rich are thin ,the poor are fat ,and right-thinking people are worrying about fatness.?
Evolution（進化）is mostly to blame. It has designed mankind to deal with lack ,not plenty .People are perfectly fit to store energy in good years to see them through lean ones. But when bad time never comes ,they are stuck with that energy ,stored around their expanding bellies.?
Thanks to rising agricultural productivity ,lean years are rarer all over the globe .According to the UN ,the number of people short of food fell from 920 m in 1980 to 799 m 20 years later ,even though the world's population increased by 1.6 billion over the period .This is mostly a cause for celebration .Mankind has won what was ,for most of his time on this planet ,his biggest battle：to ensure that he and his offspring had enough to eat. But every silver lining has a cloud ,and the result of prosperity is a new trouble.?
Fatness is the world's biggest public-health topic today—the main cause of heart disease ,which kills more ?people? these days than AIDS ,malaria（瘧疾）,war; the major risk factor in diabetes（糖尿�。�；heavily connected with cancer and other diseases .Since the World Health Organization labeled fatness an “epidemic（流行�。�”in 2000,?reports? on its fearful results have come thick and fast.?
Will public-health warnings ,combined with media pressure ,persuade people to get thinner ,just as they ?finally? put them off tobacco? Possibly .In the rich world ,sales of healthier foods are booming and new figures suggest that over the past year Americans got very slightly thinner for the first time in recorded history .But even if Americans are losing a few ounces ,it will be many years before the country solves the health problems caused by half a century's dining to overload .And ,everywhere else in the world ,people are still piling on the pounds .That's why there is now an agreement among doctors that governments should do something to stop them.?
