Making money and saving the planet don't always go hand in hand. But slowly, things are changing. As we all become more aware about the crisis facing the environment, more young people are turning their green ideas into successful businesses.Now Sir David Attenborough and Prince William want people to come up with 50 solutions to the world's biggest environmental problems by 2030. They're giving £1m to the best ones which will be known as the Earth Shot prize - the biggest environmental prize ever.The aim is to find "new solutions" that have a positive effect on environmental change and improve living standards globally, particularly those communities most at risk from climate change. The prize could go to a new technology, a new way of doing things or a new policy - basically any good idea.
