India-Pakistan nuclear war would cause ozone hole
Nuclear war between India and Pakistan would cause more than slaughter and destruction -- it would knock a big hole in the ozone layer, affecting crops, animals and people worldwide, US researchers said on Monday. Fires from burning cities would send 5 million metric tonnes of soot or more into the lowest part of Earth's atmosphere known as the troposphere, and heat from the sun would carry these blackened particles into the stratosphere, the team at the University of Colorado reported.
