Audience takeover: Your questions answered

Audience members praise and pick holes in solutions we’ve covered. Nick Holland and Kat Hawkins hear the best comments and questions and try to get answers. Among the solutions under review is a story about a man who regrew a rainforest in Ecuador. One listener is worried it’ll just get cut down again when he dies. And eyebrows are raised about nurses in Kenya using motorbikes to rescue snakebite victims. Producer: Nick Holland
