This week we're looking into our atmosphere to find out how organisms in the sea are contributing to the atmosphere on land and we'll be hearing about a new technology to help us test the atmosphere in out cities for pollutants. We'll also be finding out how the acacia tree has greatly helped the livelihoods of farmers across the Bateke Plateau. Plus, we play with magnets in question of the week!
