The former "Top Gear" host Jeremy Clarkson says the 16-year-old climate-change activist Greta Thunberg has killed the car show.

"She's an idiot," Clarkson said in an interview with the Sun editor Stuart Pink. "Going round saying we're all going to die, that's not going to solve anything my dear."

The television presenter, who's promoting season four of his Amazon Prime Video's motor series, "The Grand Tour: Seamen," says the activist is making young people think "cars are evil."

"Everyone I know under 25 isn't the slightest bit interested in cars — Greta Thunberg has killed the car show," he said. "They're taught at school, before they say 'Mummy and Daddy,' that cars are evil, and it's in their heads."

And it's not the first time Clarkson has lashed out at the young environmentalist. In October, he described her speech at the United Nations Climate Action Summit as a "full-on adolescent meltdown" and told her to "shut up and be a good girl."

Clarkson did stipulate in The Sun's interview that he and his famous colleagues were taking climate change more seriously.

The latest season of "The Grand Tour" sees the hosts Clarkson, Richard Hammond, and James May not only discuss climate change as they attempt to sail across Vietnam's Mekong River during dry weather conditions but also opt to cycle instead of drive.

"For the first time ever, we've had global warming rammed down our throats — and we've not been idiotic, it's very definitely a thing." He added: "The question is, what to do about it?"
