According to reports, Amazon founder Jeff Bezos started investing in space.

However, Bezos has also been questioned or criticized: Before investing in space tourism, the problems of the earth should be solved first. A few days ago, Bezos responded to this criticism, saying that investing in space is also beneficial to the earth and can ultimately protect the earth. This kind of investment is not to give up the earth and the human homeland.

Bezos received an award in the field of philanthropy, the Galileo Prophet of Charity Award at the Vatican. During the awards ceremony, Bezos talked about the current challenges facing the human-inhabited planet, as well as some of his thoughts on protecting the planet, including the work humanity needs to do in the medium and long term.

Bezos said that some people have asked him why he is putting so much energy into space when there are still so many unsolved problems on Earth.

Bezos answers that investing in space can ultimately protect the earth. "We go to space, not to give up the earth, but to protect the earth."

The billionaire said that the energy emitted by the sun can be harvested in unlimited amounts anywhere. In space, humans can also use solar energy and other resources, and the development of space activities will not harm the earth. "The earth is our garden and should be taken care of."
