Microscopic marine algae called phytoplankton that produce half the world's oxygen and support most ocean life have been declining dramatically over the past century, Canadian researchers say.
"We should be very concerned it's extremely disturbing," said Daniel Boyce, lead author of the study published Wednesday in Nature.
"Phytoplankton are the base of the marine ecosystem. It's the fuel on which it runs . Changes in phytoplankton abundance will ultimately affect everything higher in the food chain from tiny little zooplankton all the way up to large whales, valuable fisheries and humans at the top."
