 Nyombi set up a non-profit organisation called Earth Volunteers to mobilise young people like him who want to promote the fight against climate change. They have planted more than 50,000 trees and reached more than 13,500 students. He's also trying to get a climate school off the ground. So today we are growing. We have over 300 members. We have a project known as Climate School 2030 with a mission to reach at least 1.5 million.
