The ocean is full of charge plate , a grim marker of theAnthropocene . There are float , continent - sizepatchesof it in the Pacific and Atlantic Oceans , and there are newly formed ones in the Arctic . There are some uninhabited islands that aredrowningin the stuff .
Weirdly , though , scientist have come to the conclusion that , based on the amount of plastic we make every yr , there is only about one - hundredth as much of the credit card floating around as the numbers would suggest . Although there are many potential explanations for this , a new work available on the pre - print serverbioRxivhas reason out that microbes are breaking the charge plate down .
This may vocalize utterly outlandish , but just last class , researchers discovered that a new distinguish species of bacterium was able to shatter the molecular bonds of polyethylene terephthalate ( PET ) , one of the most coarse forms of charge card . They ’re literally using it as afood source .
unremarkably , PET takes 450 year to wholly degrade in the environment . These bacterium make short work of it in just six week . It ’s this info that has led to a team of researchers from the Pompeu Fabra University in Barcelona to suspect that the deficiency of charge card in the ocean is largely down to these microscopic critter .
Using mathematical modeling , they have come up to the conclusion that other geological processes or counting errors can not explicate the variant between the worldwide rate of plastic production and its “ underwhelming ” presence at sea . It ’s somewhat circumstantial , but it ’s a self-coloured idea .
At a glance , this seems like good news – a growing number of charge card - consuming microbes will aid limit the absolutely disgraceful amounts of charge plate that ’s dumped into the sea , much of which is run through by creature that conk , or make it long enough to be eat by us . However , you ’d have to be quite morally repugnant to suggests that this means we can keep dumping charge plate in the oceans without consequence .
Still , if these bacteria can be encouraged to proliferate across the ocean , it would subjugate humanity ’s negative impact on them , and few would claim that this is a bad idea .
We perhaps should n’t trust on these bacteria too heavily , though – it ’s possible that muckle of the plastic is sinking down beneath the surface and being buried within the seafloor . Ultimately , this will resurface again as a bizarre new rock type some have called a “ plastiobreccia ” . Either way , it ’s difficult to retrace it all .
In any case , we are still dumping a horrific amount of plastic into the sea at present . Although recycling has its place , thing arguably wo n’t change until plastic is phase out in favor of bioplastic , the character that quickly breaks down in any environment after it has been used .
