In a speech at the Vatican, Jeff Bezos addressed people who ask why he invests "so much into space."
The former Amazon CEO said investing in going to space will benefit the Earth and "protect it."
The goal for Blue Origin, Bezos has previously said, is to make traveling to space cheaper, more frequent, and more accessible.
In 2018, Bezos said Blue Origin was "the most important work I'm doing," in an interview with Axel Springer's CEO Mathias Döpfner.
Bezos founded the Bezos Earth Fund in 2020, which will disburse $10 billion, committed by Bezos, in the current decade to fight climate change and protect nature.
