No, we are not good at that. We have dire warnings of extreme catastrophes heading our way for decades now and instead of fixing what is broken, we collectively decide to race to our extinction faster.
Modern Humans have been around and successful for 10s of thousands of years. This might be a genetic dead end in the relatively near short term, but I bet we and at least one branch of our descendants will live for many more 10s or 100s of thousands of years.
