Prince Harry's passion for environmentalism means that he only wants "two children, maximum," in an effort to limit his family's carbon footprint.
In his interview for Meghan's September Vogue edit, Jane Goodall cautioned Harry to not have "too many babies" out of concern for the worldwide population growth.
The Duke of Sussex replied: "Two, maximum!"
The 34-year-old had much to say about his social consciousness when it came to the environment.
"I’ve always thought: this place is borrowed. And, surely, as intelligent as we all are, or as evolved as we all are supposed to be, we should be able to leave something better behind for the next generation," the father of one said.
The Sussex family have been committed to raising awareness for the environment this month.
The Duke and Duchess attended the Lion King Premiere in London, to support Protect The Pride, a global conservation campaign to support efforts protecting the rapidly diminishing lion population across Africa.
The Sussex royal Instagram account shared a post of the royal couple at the event, writing in the caption, "The Duke and Duchess are committed to advancing conservation efforts across Africa and around the world, and working with communities to ensure a sustainable future for the planet."
