Stewart Brand at TED 2013
The dawn of de-extinction. Are you ready?  (transcript)
Summary
The speaker's stories always surprise us.

We know that human semen and a woman’s eggs are extracted, frozen and stored. Thus, of course, frozen animals' DNA is properly conducted, isn't it?

I didn't know that even pretty badly bird's DNA can be reassembled the whole genome and the whole bird. 1)

The DNA from even dead last animal's ear is taken and planted it as a cloned egg in a similar current animal. A live baby can be born. Its animal was thought extinct. 2)

There's no breeding pairs life, but a cloned baby can be born, 3) and IPS (induced pluripotent stem) cells can be turned into germ cells of sperm and eggs. 4)

His activity: Revive and Restore that push de-extinction generally is human responsibility. 5)
It's not creating ancient species but it's recreating extinct ecosystem. 6)
Human interference in nature made a lot of animals and birds go extinct but changed the whole ecosystem. 7)

The speaker tells us that realizing extinction, protecting, reproducing and returning the whole ecosystem are human responsibilities.
The title has been meant to extinct extinction.
