Biggest threat to humanity

I think the biggest threat to humanity is us, humans and the threat of nuclear war. Since 1942 when the US created the first nuclear weapon there’s always been a threat and risk for a nuclear war. It’s simple, the work of humans created a weapon that could destroy humanity. in 1945 The United States detonates a uranium bomb over Hiroshima, Japan killing more than 140,000 people within months. Many more later die from radiation-related illnesses. (ICAN, 2010) Which later led to, the UK, France, China and the Soviet Union testing their own nuclear/radiation bombs. Humans have tried to stop the creation of nuclear weapons by creating campaigns, petitions and rallying. In 1982 One million people gathered in New York City’s Central Park in support of the nuclear freeze movement. (ICAN, 2010)

Why do I think this is the biggest threat to humanity? It is something that has been looming over us for decades. There are reasons why countries are still testing these weapons and occasionally threat other countries with their nuclear weapons. A recent consideration of using nuclear weapons was by Russia, Vladimir Putin has suggested that he would consider using nuclear weapons if confronted with a NATO military response in Ukraine (Lynas, 2022) . If a Nuclear attack were to happen, not only the initial attack will be bad but also the aftermath. It will be devastating environmentally and for the human health. Radioactive dust will cause deadly amount of radiation, and more deadly ‘nuclear winter’ could happen after a nuclear war. (Roser, 2022) Nuclear winter is where Smoke from the fires started by nuclear weapons, especially the black, sooty. smoke from cities and industrial facilities, would be heated by the Sun, lofted into. the upper stratosphere, and spread globally, lasting for years. (Robock, 2010) The world’s food production would fail and billions of people would starve. (Roser, 2022)
