Elizabeth Wathuti, the 23-year-old climate activist planting trees in Kenya

Brazil’s president told world leaders at the UN that the Amazon is not under threat and that it is wrong to say the rainforest is the lungs of the earth. Our guest Elizabeth Wathuti is a young Kenyan who has been fighting to keep forests alive since she was seven. She is the founder of Green Generation Initiative, which has planted 30,000 trees in Kenya. Motivated to take whatever action is possible, she admits the whole world needs to join her if there is any chance of making a real difference.
