But biological responses to food in rats and humans are surprisingly similar, and provide at least a strong indication that the same sorts of reactions happen when we eat fake fat and sugar.

In my lifetime there have been a large number of predicted nutritional apocalypses, caused by overpopulation, lack of biological diversity in our food supply, genetic engineering run amok, acid rain, too little ozone, too much ozone and, finally, global warming.

Thanks to technological and biological advances, we now grow more food on fewer acres at less cost.

Though smelling food isn't a survival skill anymore, it still serves a biological purpose.

In January, the Food and Drug Administration approved Kalydeco, the first drug to actually reverse the biological changes that cause the lung-destroying disease.

The study, published in the international journal Biological Invasions, suggested that European hares exhibit strong competition for habitat space and food resources with native species, most notably other hare species.

Add to this an inevitable end to stretching productivity per acre with further technical advances as we reach some ultimate biological limit, and we would be irresponsible to assume that agricultural science will solve all future problems of food supply.
