Building blocks of ocean food web in rapid decline as plankton productivity plungesDec 22, 2018They're teeny, tiny plants and organisms but their impact on ocean life is huge.Phytoplankton and zooplankton that live near the surface are the base of the ocean's food system. Everything from small fish, big fish, whales and seabirds depend on their productivity."They actually determine what's going to happen, how much energy is going to be available for the rest of the food chain," explained Pierre Pepin, a senior researcher with the Department of Fisheries and Oceans in St. John's."Based on the measurements that we've been taking in this region, we've seen pretty close to 50 per cent decline in the overall biomass of zooplankton," said Pepin. "So that's pretty dramatic."Scientists say local testing reveals half the amount of plankton in a square metre of water today. It's not just a problem here, declining plankton numbers are a global phenomenon.(Source)
First they came for the insects, but I didn't realize that they were important because I hate mosquitoes and didn't really pay attention during biology.
Then they came for the phytoplankton and zooplankton, and, well, same reasons.
Then they came for all the fish in the ocean, but I switched to chicken, so no big deal, right?
Then they came for my oxygen and then it was too late...
