Lisa Rogers

It’s really important that everybody does what they can to slow down global warming. If we don't, the planet will adapt and survive - it's us who would suffer

Former Big Breakfast star Lisa Rogers has gone on to present other Channel 4 programmes including Scrapheap Challenge as well as football shows for both ITV and BBC, but she also knows a thing or two about cars, having fronted Sky One’s Vroom Vroom and Carlton’s Pulling Power motoring programmes.

She has converted her own car to run on pure vegetable oil. “I’ve been a member of Greenpeace for years, but possibly didn’t live as green a lifestyle as I should have done,” she says. “Having had two children I’ve started to think about what sort of planet I’ll be leaving them to live on.”
