Abnormal heat and forest fires, like those that engulfed half of Russia in the summer of 2010, are dangerous not only to human life and health. Much more dangerous are their possible global consequences, or rather, one thing that seems unlikely to many of us: famine. In this book, Lester Brown argues that it is not world terrorism, not nuclear or chemical weapons, but precisely famine, which occurs, among other things, due to change climate change, is the world's leading threat. The threat is very real: grain exports from Russia have been stopped, world prices for wheat 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 destruction. Its essence is a reduction in consumption (food and energy resources), restoration of the Earth's land, water and biological resources, transition to a new, environmentally friendly economic model of life, and global structural reform of government administration. Brown's ideas outlined in this book might seem utopian - if the richest people in America (like Bill Gates or Warren Buffett), who noticed the threat before others, did not invest billions in their implementation. For a wide range of readers.
