These are the ‘only two countries that would survive’ if World War 3 broke out using nuclear weapons

But the true devastation is happened upon the people who survive these devastating blasts and their radioactive fallout. Jacobson said that after this, three billion people would be left alive, but that life would be completely unrecognizable.

“Places like Iowa and Ukraine would be just snow for 10 years, and so agriculture would fail. When agriculture fails, people just die,” she said, before Bartlett raised the question of where could even be safe in such a scenario.

It turns out that people living in New Zealand and Australia are likely the only ones to make it through the nuclear winter, with Jacobson stating that the Nature study shows that these might be the only place where you can grow food, or even go outside.
