Nuclear war would 'end civilization' with famine, study says

A nuclear war between India and Pakistan would set off a global famine that could kill two billion people and effectively end human civilization, a study said Tuesday.

Even if limited in scope, a conflict with nuclear weapons would wreak havoc in the atmosphere and devastate crop yields, with the effects multiplied as global food markets went into turmoil, the report said.

The Nobel Peace Prize-winning International Physicians for the Prevention of Nuclear War and Physicians for Social Responsibility released an initial peer-reviewed study in April 2012 that predicted a nuclear famine could kill more than a billion people.
