Exploring the unintended consequences of reducing air pollution, she makes the case for a better understanding of marine cloud brightening — or intentionally adding sea salt aerosols to clouds over the ocean, which could reflect sunlight back into space and potentially reduce global warming.

Countries around the world waste huge amounts of food every year: roughly a fifth of food items in the US are tossed because consumers aren't sure how to interpret expiration labels. But most groceries are still perfectly safe to eat past their expiration dates. If the dates on our food don't tell us that something's gone bad, what do they tell us? Carolyn Beans shares how to prevent food waste. This TED-Ed lesson was directed by Anton Bogaty, narrated by Alexandra Panzer and the music is by Salil Bhayani, cAMP Studio.
