Sir David Attenborough isn't just the voice behind all of our favorite nature documentaries, he's the voice behind conservationism as a whole. The British naturalist narrated the epic BBC series "Planet Earth," aided in the launch of the vast natural history project called ARKive, and has even had several newly discovered species named after him. His latest project has been an immersive exploration of the Great Barrier Reef, and with that introduction, Attenborough took to Reddit to let the Internet ask him anything.

Attenborough discussed how the Earth's landscapes and animals have changed over the years, what it's like to be in the Great Barrier Reef, and his favorite moments from his long and prosperous career.

One Redditor asked Attenborough what humanity can do to be better co-habitants of Earth with nature. "We need to slow the speed of our population growth," Attenborough replied.

He has truly explored every corner of the earth –and if you're wondering: no, he says he would not like to visit space.

He seems like he's seen it all, so the top-voted question truly put into perspective what exactly amazes Attenborough the most.

Alongside his mentions of his current project, Attenborough discussed many of the amazing things he's seen and done over the years, as well as the animals that left the biggest impression on him.

Things got pretty deep:

Attenborough glimpsed the future.

Attenborough even expressed his deepest regret.
