Prince Harry says he and Meghan Markle will have just two children — to help combat climate change, of course

The U.K.'s Prince Harry and his American wife, Meghan Markle, will have only two children "maximum," apparently due in part to a dedication to eradicating climate change.

What are the details?

Prince Harry interviewed conservationist Jane Goodall for August's British Vogue. Markle guest-edited the same month's issue.

During the sit-down, Prince Harry said that today's current climate is "terrifying," both literally and metaphorically.

"What we need to remind everybody is: these are all things that are happening now," he said of the effects of climate change. "We are already living in it. We are the frog in the water, and it's already been brought to a boil. Which is terrifying."

Goodall added, "Happening and happened. It is terrifying. Especially as you've just had a baby."

Prince Harry responded, "I know. It does make it different. I think, weirdly because of the people that I've met and the places I've been fortunate enough to go to, I've always had a connection and a love for nature. I view it differently now, without question. But I've always wanted to try and ensure that, even before having a child and hoping to have children."

"Not too many!" Goodall fired back, which prompted the Duke of Sussex to respond, "Two maximum!"

"But I've always thought," he continued, "this place is borrowed. And, surely, as intelligent as we all are, or as evolved as we are all supposed to be, we should be able to leave something better behind for the next generation."

What else?

Prince Harry also spoke about racism being an "unconscious bias" for most people.

"Despite the fact that if you go up to someone and say, 'What you've just said, or the way you've behaved, is racist,' they'll turn around and say, 'I'm not a racist,'" he complained. "'I'm not saying you're a racist, I'm just saying that your unconscious bias is proving that because of the way that you've been brought up, the environment you've been brought up in, suggests that you have this point of view — unconscious point of view — where naturally you will look at someone in a different way.'"

"And that is the point at which people start to have to understand," he added.

Prince Harry defined "unconscious bias" as "something which so many people don't understand, why they feel the way they do."
