A study published today in the journal Nature brings big bad news about the state of life on our planet. Researchers from Nova Scotia conclude that levels of phytoplankton have fallen by about one percent per year for the last several decades. That decline is correlated with rising water temperatures. Add it up, and that’s a significant decline.
Phytoplankton are the base of most of the oceans’ food webs. If they were to go away, much life in the ocean would be unable to survive. Nobody knows what might happen then.
