Cold-water fish, snow-dwelling bugs and some grasses have evolved natural antifreeze proteins to avoid turning to ice cubes. Peter Davies, a biologist at Queen's University in Ontario, discusses how these antifreeze substances work, and their applications for human problems--like keeping the ice out of ice cream.
In Full Planet, Empty Plates: The New Geopolitics of Food Scarcity, Lester Brown says the world's food supply is tightening, and the reasons are many.
