One of the world’s great organizations opposing nuclear weapons is International Physicians for the Prevention of Nuclear War (IPPNW). Several years ago they won the Nobel Peace Prize.
Now IPPNW has issued a second edition of their report about how an exchange of nuclear weapons could cause a global famine (“nuclear famine”).
The report is titled, “Nuclear Famine: Two Billion People at Risk?—Global Impacts of Limited Nuclear War on Agriculture, Food Supplies, and Human Nutrition.” It is at this link: https://www.ippnw.org/nuclear-famine.html
The report explains how even the relatively small nuclear arsenals of countries such as India and Pakistan could cause devastating and long lasting, global damage to the Earth’s ecosystems.
Essentially, a nuclear war using as few as 100 weapons anywhere in the world would disrupt the global climate and agricultural production so severely that the lives of well over two billion people, particularly the already food-insecure people of a number of countries, would be would be threatened by nuclear war-induced famine!
There are SO MANY REASONS for abolishing nuclear weapons! I encourage every person to join this movement for human survival.
