Nuclear war will cause the greatest famine the earth has ever witnessed and it will cause more than 5 billions people to lose their life most of them due to starvation and others of war effect and radiation affects.
A smaller regional nuclear conflict could also result in the starvation of billions of people, according to peer-reviewed research published in Nature Food on Monday. These sobering findings illustrate the far-reaching effects of nuclear war as tensions between several nuclear-armed states soar amid the ongoing conflict in Ukraine. A full-scale nuclear war between Russia and the U.S. could cause a global famine and kill more than 5 billion people.
One of the authors, Professor Alan Roebuck, stated, "The numbers tell us one thing: We must prevent a nuclear war from ever occurring." According to UN Secretary-General Antonio Guterres, the warning comes as "humanity is just one misunderstanding, one error away from nuclear destruction."
Estimated number of nuclear weapons with different countries at present
There are thought to be 13,080 nuclear warheads in existence right now. Although this number is considerably lower than either the United States or Russia had at the height of the Cold War, it is noteworthy that there are now more nuclear-armed nations than there were 30–40 years ago. With an estimated 6,257 total warheads, Russia has the most nuclear weapons in existence right now. The START II treaty currently limits both the United States and Russia to a total of 1550 deployed forces. Of these, 1,458 are currently deployed, 3039 are inactive but could be activated, and 1,760 are retired and awaiting dismantlement. With 5,550 nuclear weapons in total—1,389 active, 2,361 inactive but ready, and 1,800 scheduled for destruction—the United States is not far behind. By the date today most of the countries have nuclear weapons and these countries with the nuclear weapons are known as nuclear powers.
Russia — 6000+
United States — 5500+
China — 500+
France — 290+
United Kingdom — 220+
Pakistan — 200+
India — 200+
Israel — 100+
North Korea — 50+
As seen in the above data Russia, China and USA are leading the race in this run and these are the three nations. And these countries are not having very good relationship at present either due to RUSSIA-UKRAINE war with NATO involved or the China Taiwan war with the direct US involvement. So these all things are leading us to the nuclear war in the coming future.
What will happen after the nuclear war?
Climate models simulating six distinct nuclear war scenarios predict that soot blasted into the atmosphere after a nuclear exchange will destroy food productivity by obstructing sunshine and decreasing temperatures. The models showed that even a small, localized nuclear war could have far-reaching effects and lead to food shortages so severe they would kill billions of people. They examined changes to agricultural production and trade in five scenarios for how smaller nuclear wars between India and Pakistan and one large war between Russia and the U.S. could play out.
According to the researchers, in the most dire scenario—a large-scale nuclear conflict between the United States and Russia—more than 75% of the world's population will be hungry within two years, including nearly all countries—aside from Australia and a few in Africa and South America. The researchers discovered that within two years of a lesser exchange between India and Pakistan, more than two billion people may perish from starvation. The most significant NCrop losses would occur in countries at mid-high latitudes, including exporting giants like the U.S. and Russia, and they would probably lead to export limitations that would be extremely difficult for import-dependent economies in Africa and the Middle East.
In the immediate aftermath of a short nuclear war, savings from compensating measures like using crops given to cattle to feed people or eliminating all food waste may be of some assistance, but they would be of little use after major battles, according to the researchers.
Additional effects of nuclear conflict on food production. The impact of soot added to the atmosphere and calories were specifically evaluated in the research scenarios. They observe that just a small portion of human nutritional requirements are taken into account by caloric intake and say that future studies should examine the effects on the numerous proteins and micronutrients that are essential to human health. Beyond the possibility of starting a nuclear winter, nuclear war would potentially have far-reaching effects. The ozone layer could be destroyed and more UV radiation could reach the surface of the globe if nuclear explosions heat the atmosphere. Large areas would be affected by radioactive contamination, and vital products used in food production as well as infrastructure might be destroyed. The researchers recommended that future studies take these concerns into account.
The researchers noted that it's conceivable for humans to modify agricultural systems to function in the event of nuclear winter, but they cautioned that such changes would be difficult to put into place in time for the model-predicted lethal second year. Alternative food sources like mushrooms, seaweed, insects, and cellular protein could also help lessen the impact but were not examined using the models, the researchers said. Cold-adapted crops that require less light, greenhouses, or switching to these sources could also help.
The study builds on decades of scientific warnings that even a little nuclear exchange may have disastrous effects on the entire world and provides yet another sobering insight into the terrible effects of nuclear war. Many of these effects are unknown due to the complexity of the planetary ecology, but scientists think that a nuclear exchange would cause a nuclear winter because the soot released into the sky would block out the sun and cause temperatures to drop sharply. A nuclear winter, according to models, would result in widespread starvation, drastic changes in ocean chemistry, which would probably be devastating for marine organisms like coral reefs, and might perhaps usher in a new ice age.
The analysis is released at a time when many nations possessing nuclear weapons are on edge as a result of Russia's invasion of Ukraine. Nations and experts have expressed concern that the crisis, which has seen a nuclear power station used as a battleground and threats from President Vladimir Putin to use nuclear weapons, could result in a catastrophic disaster. Russia is one of nine countries with nuclear weapons, along with the United States, United Kingdom, France, China, India, Pakistan, North Korea, and Israel.
