Sir David Attenborough is sharing his grave concerns for the future of the planet.

In an interview with BBC Breakfast’s Louise Minchin, he hopes people can change this planet for the better.

Minchin asks the 94-year-old natural historian, “If there’s one choice to make today, what choice would you like people to make?”

“Don’t waste,” he replies. “Don’t waste anything. Don’t waste electricity, don’t waste food, don’t waste power. Just treat the natural world as though it’s precious, which it is. And don’t squander those bits of it that we have control of.”

Later in the interview, Minchin asks Attenborough how he feels about the younger generation taking part in the fight against climate change.

“That is a great hope. That is the most important hope,” he responds. “And most important place where there should be hope, it’s their world and it’s their tomorrow.”
