Abnormal heat and forest fires like those that swept half of Russia in the summer of 2010 are dangerous not only for the life and health of people. Much more dangerous are their possible global consequences, or rather, one thing that seems unlikely to many of us: hunger. In this book, Lester Brown argues that not world terrorism, not nuclear or chemical weapons, but hunger, including due to climate change, is the main threat to the world. The threat is quite real: grain exports from Russia have been stopped, world wheat prices have doubled. If other major exporters suffer comparable losses due to natural disasters, a global food crisis will be inevitable. Lester Brown, winner of the UN Environment Prize, has a plan to save humanity from doom.
