NewzKidz: The Royal Baby, Supermarket food waste, UN Climate Change report, Leonardo da Vinci, Adverts in the Sky, Drones helping Doctors and UK Copper Coins

This week we’re talking about the Royal Baby, how supermarkets are tackling food waste, the very important report from the United Nations about climate change and the state of our planet, a new discovery about Leonardo da Vinci, why we might start seeing adverts in the sky, how drones are helping doctors and patients, and why the UK has decided to keep its copper coins. Zara and I also talk about food waste and what we can do to deal with this problem.
