Have you thought about quitting your job because of climate change? Research shows more and more people are worried about their career’s impact on the planet. So this week The Climate Question hears from four people from around the world who’ve taken the plunge and done it. Luke Jones meets an air steward who's swapped flying for teaching; a restaurant critic who's become a tree-planter; a fossil fuel company engineer who's switching to working in renewables; and a multinational CEO turned sustainable business campaigner.
