It's still science week and we have moved on from rockets to straws. Suzanne's top topic, she is in her element talking about the straws. Dr. David from the last episode stuck around for this one, and we're joined by Dr. Jessamyn Fairfield, nanoscientist and comedian. Yes, straws, keep cups, shampoo, vegetarianism... what is good, what is bad, what is worth doing to save the planet... is it worth doing anything at all? 

Also discussed, Greta Thunberg, fast fashion, rising sea levels and baking in space.
