There is evidence that we are headed into what would be the planet's sixth mass extinction. It's hard to know for sure if you're in one because a mass extinction is an event where over 75 percent of the species on the planet die out over a - usually about a million-year period. The fastest it might happen is in hundreds of thousands of years.

We'll all die out eventually. Humans will be gone. And all I'm saying is, when people worry about polar bears disappearing or whatever, it's like, 'Well that's life, things will come and go, we'll find new species.'

If our extinction proceeds slowly enough to allow a moment of horrified realization, the doers of the deed will likely be quite taken aback on realizing that they have actually destroyed the world. Therefore I suggest that if the Earth is destroyed, it will probably be by mistake.

Some day we'll move into space and start ensuring the survival of our species beyond Earth, whether it happens in a hundred years or a thousand.

If we were to wipe out insects alone on this planet, the rest of life and humanity with it would mostly disappear from the land. Within a few months.

Every species becomes extinct; at some point, we will go extinct. The question is, as Homo sapiens, are we going to be able to adapt to the change that we're actually part of? We're causing such dramatic changes to the planet, so yes, you do stop and think, 'I wonder where we're headed.'

We'll lose more species of plants and animals between 2000 and 2065 than we've lost in the last 65 million years. If we don't find answers to these problems, we're gonna be victims of this extinction event that we're at fault for.

I don't think we are going to become extinct. We're very clever and extremely resourceful - and we will find ways of preserving ourselves, of that I'm sure. But whether our lives will be as rich as they are now is another question.

Species go extinct because there are historical contraints built into a given body or a given design.
