A Look at the Little Guys


In the third podcast, listeners go to the base of the marine food web. Dr. Kendra Daily explains that although they may be microscopic, phytoplankton and zooplankton have a big impact on larger species that we eat. She discusses the phenomenon of “marine snow” – a mixture of dead plankton and oil droplets – that can impact other important microscopic organisms on the seafloor. Damage to these tiny creatures has a “cascade effect” on the health of the food web, with both ecological and economic consequences.
