Simone Bianco and Tom Zimmerman: The wonderful world of life in a drop of water

'Hold your breath,' says inventor Tom Zimmerman. 'This is the world without plankton.' These tiny organisms produce two-thirds of our planet's oxygen -- without them, life as we know it wouldn't exist. In this talk and tech demo, Zimmerman and cell engineer Simone Bianco hook up a 3D microscope to a drop of water and take you scuba diving with plankton. Learn more about these mesmerizing creatures and get inspired to protect them against ongoing threats from climate change.
