Climate change is the biggest thread to life on our planet. How accurate is this statement? Are there any other big threats to mankind?

It is claimed that global warming is the chief

threat

to human civilization.

statement because people can find technological solutions to

For instance

, the United States of America alone has enough nuclear warheads to wipe out every man, woman and child on earth with its arsenal and the Cuban Missile Crisis in the 1960s demonstrated how close it is possible to come to global nuclear war. In conclusion, climate change is not the gravest peril the earth faces because we have the technological capability to solve it and the
