Prince William criticizes space tourism at the expense of solving climate change. He says innovators should be focused on saving Earth, not looking for a new planet to inhabit. “We need some of the world’s greatest brains and minds.

This didn’t go well with William Shatner who recently took a trip to space aboard Jeff Bezos’ Blue Origin rocket.

The “Star Trek” actor, 90, has hit back at Prince William.

Prince William during an interview was asked whether space tourism is the right way to take care of the earth, he replied:

“We need some of the world’s greatest brains and minds fixed on trying to repair this planet, not trying to find the next place to go and live,” William told the BBC in an interview airing Thursday. “I think that ultimately is what sold it for me – that really is quite crucial to be focusing on this [planet] rather than giving up and heading out into space to try and think of solutions for the future.”

During an interview with Entertainment Tonight, Shatner addressed the comments.

“He’s got the wrong idea here, it’s not to go, ‘Oh look at me, I’m in space,'” the actor insisted.

He then offered up a message for William, 39.

I would tell the prince – and I hope the prince gets this message – this is a baby step of getting all those polluting industries off of Earth,” he said. “You can build a base 250, 280 miles above the Earth and send that power down here.”

When pressed about Williams’ school of thought – fixing Earth rather than leaving it – Shatner offered that people should “fix some stuff down here” after all.

“Everybody in their lifetime needs to be reminded: You’re important, you’re beautiful do something important today,” he added.

“That’s what that trip did to me – it reminded me of death facing me because of my age, but also how to protect you in the years to come.”

In his discussion with the BBC, William also raised concerns about the carbon cost of space flights.

Bezos, Virgin’s Richard Branson, and SpaceX founder Elon Musk have all competitively ventured into space tourism as of late and Musk frequently talks about the importance of making humankind “interplanetary” especially if Earth becomes uninhabitable.

Shatner, best known as Captain Kirk on “Star Trek,” remains 1st oldest person ever to go into space.
