This website, created by Steven Starr, a senior scientist for Physicians for Social Responsibility, is available in four languages: English, Russian, Hebrew, and Chinese. The site describes the deadly long-term environmental consequences of nuclear war that threaten continued human survival.  Virtually any nuclear war, even one fought with less than 1% of the deployed and operational nuclear arsenals, will cause catastrophic disruptions of global climate and massive destruction of Earth's protective ozone layer, resulting in global nuclear famine.  The site also includes a photo gallery from Hiroshima, Japan, the first city in the world to be annihilated by an atomic bomb in 1945; there is also a nuclear firestorm simulator, which allows you to type in any address or city, select a weapon size, and then illustrate the size of the resulting nuclear firestorm caused by the detonation of the weapon.
