Could We Destroy the Earth?

There are a lot of nuclear weapons on Earth, so many that we often say it’s enough to “destroy the world several times over.” But could we? Well, that depends on what you mean. Also...no matter what you mean, probably not. The Earth is pretty sturdy and people are pretty good at surviving and even after all this time and technology, our biggest weapons are pretty puny on a universal scale. ---------- Messages from our Subbable Subscribers To SciShow: DO EPISODES EXPLAINING REALY GOOD MATH TECHNIQUES !!! - Aaron Schwartz Hey best friend, I love you. - Justice Hitchcock I love Milly Fox and look up to Adam Savage. - Miles from Sydney, AUS I love you, Nicholas. - Marisse M.
