Harry discussed environment, responsibility and climate change with primatologist Jane Goodall in an interview for the September issue of British Vogue, which was guest-edited by his wife.

The prince, who had a son Archie with Meghan in May, said that fatherhood has pushed his "connection and a love for nature" to a new level.

As he mentioned his intention to have more than one child he was interrupted by the scientist, who called for him not to have "too many".

The prince responded "two, maximum," before voicing his environmental concerns for the generations to come.

"I've always thought: this place is borrowed. And, surely, being 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 Duke of Sussex said.

Goodall and Harry agreed that the state of the environment is already "terrifying".

"How many clues does nature have to give us before we actually learn, or wake ourselves up to the damage and the destruction that we're causing," the prince asked.

In the wide-ranging conversation the two also discussed unconscious bias and how human behaviour is determined by the environment.
