"When will Earth die? A million years? A billion years?" Did the words "tomorrow", "next week", "next year" not suit your argument?

It's also ignoring the word "ensure", the longer we sit idly by, the less sure we can be. "If we can't in a million years develop technology to survive we won't be able to do it in the next 50 years." Obviously, but what's a million years got to do with anything?
