Should wealthy individuals and nations shoulder more of the burden in addressing climate change? Pulitzer Prize-winning climate journalist Elizabeth Kolbert argues that Big Tech leaders like Jeff Bezos and Elon Musk should shift more of their focus to fighting for our own planet's survival, instead of space exploration. "We're doing as much as we can to make life difficult on planet Earth for ourselves. But there's virtually nothing we could do to make it as difficult as life on Mars, where there's, among other things, no oxygen." Kolbert, the author of Under a White Sky, discusses why it's so crucial for a few rich countries to bear most of the climate burden, since they're also the biggest emitters. Her conversation with Ian Bremmer is featured in the upcoming episode of GZERO World, airing on US public television stations starting this Friday, April 16. Check local listings.
