While in Canada, plankton has declined by half, a Scottish researcher warns of the collapse of the oceans. The consequences would be dramatic.

Since Newfoundland and Labrador, there has been a dramatic decline in plankton since 2014. Plankton is the foundation of the entire ocean food chain. In addition, the microscopic creatures provide 50 to 80 percent of the oxygen in the earth's atmosphere and eliminate most of the carbon dioxide. However, the pollution of the oceans massively increases the plankton. According to Scottish researcher Howard Dryden, a turnaround must be made in ten years, otherwise the oceans' ecosystem will collapse. The researchers at the Tara-Ocean project are also worried about the plankton. From 2012 to 2015, they collected 35,000 plankton samples from the oceans to learn how the tiny creatures influence and are influenced by the environment. Plankton is the term used to describe those organisms that live in the water and whose swimming direction is determined by the species A distinction is made between zooplankton (animal plankton) and phytoplankton (plant plankton). The term plankton comes from the Greek and means something like "straying". One of these straying is a parasitic live flea of the genus Phronima. He uses his gelatinous shell as a Schutzhülle.Im home in the Mediterranean is this Sapphirina-Ruderfusskrebs. Tiny platelets sit on his skin, reflecting and breaking the light so that it shimmers colorfully. In the Indian Ocean, the researchers discovered the diatom Lauderia annulata. The green-yellow particles are chloroplasts.
Some organisms are only temporary plankton: This worm is only temporarily on the seabed. However, for reproduction, it rises and drifts through the water.However, this journeyman has no name yet. He was being fished by the researchers from the Indian Ocean.Even tiny medusae (jellyfish) are called plankton.The scientists were not content merely to catalog the different species. They also studied the interaction between the tiny organisms.On this shot, a small medusa tries to eat a tiny fish as well.
The Canadian Fisheries and Marine Authority (DFO) has identified a worrying plankton death in the waters off Newfoundland and Labrador. According to DFO researcher Pierre Pepin, all zooplankton biomass there has dropped by 50 percent over the last three to four years. In addition to the death of zooplankton, the animal plankton, Pepin has also noted a decline in phytoplankton, the plant plankton, as Cbc.ca reports.Knowledge Push

Plankton is the basis of the entire food chain of the oceans. Fish, seabirds, whales and seals: they are all dependent on plankton. What the decline means, Pepin illustrates by comparison: It's like going to a grocery store and all the racks are only half full. He fears that something fundamental has changed in the food chain of the oceans.
First the sea, then the land
Pepin's concern is shared by Scottish marine biologist Howard Dryden. He warns in a report by the environmental organization Global Oceanic Environmental Survey that the oceans will be so poisoned by 2045 that within five years, most fish, birds and marine mammals will die out. According to Dryden, that would have devastating consequences for life on land.
"If we allow the marine ecosystem to be destroyed, the mainland ecosystem will fail a few years later," Dryden told Express.co.uk . "We only have about 10 years to turn things around and not just eliminate plastic, but toxic chemicals like those found in thousands of products, from lipstick to sun creams." Failure to do so would lead to a collapse of the entire marine ecosystem ,
Dryden notes that it is not the industry that is responsible for the death of plankton, but the people who use cosmetics and other products that are full of toxic chemicals. These include oxybenzone, which does not dissolve in the water, but attaches to smaller objects such as plankton, kills it slowly and other organisms that feed on plankton, poisoned.
The threat to the marine life emanating from Oxybenzon, including the US state of Hawaii has recognized. There the use of the compound in sun creams from 1 January 2021 is prohibited. In addition, Dryden calls for a ban on wood burning by 2020, a comprehensive ban on disposable plastic and equipment recycling without pollutant emissions. In addition, by 2030, all industries would have to be free of toxic waste.
Only if all this is achieved could the seas recover by 2050, says Dryden. If he does not succeed, he sees black. "To put it bluntly, if we do nothing to improve the situation, humanity can not survive."
Most important oxygen supplier
The loss of plankton would have dramatic consequences, not only because of the loss of an important food source in the sea. Because phytoplankton also produces 50 to 80 percent of the oxygen in the earth's atmosphere and eliminates most of the carbon dioxide. The fact that plankton has been reduced by more than 40 percent globally through human influence since the 1950s is one of the main causes of climate change for Dryden. Against this background, the increased plankton dying off Newfoundland and Labrador seems even more dramatic.
