More than 5 billion people will die in case of a nuclear war between Russia and the United States of America

According to Mouood, quoting by Didehban:

More than 5 billion people will die in case of a nuclear war between Russia and the United States of America.

Nature Food magazine published the results of a study by Rutgers University scientists in the event of World War III, 360 million people will die directly from nuclear weapons, and another 5 billion will die from famine and its consequences.

The nuclear winter caused by this war will kill them. 

As a result of nuclear attacks, more than 150 million tons of soot will release into the atmosphere causing the Nuclear Winter across the planet. Bombs aimed at cities and industrial areas lead to firestorms, releasing significant amounts of combustion particles into the upper atmosphere. They will spread across the earth and lead to rapid cooling.

These pollutions cause several decades of disturbance in the earth’s climate and will affect food production systems on the surface and oceans.
