There may be some light at the end of the tunnel.

Researchers from Yale University have claimed to found a fungi in the Amazon rainforests which can eat up polyurethane. In a paper published in the journal "Applied and Environmental Microbiology" they have mentioned that
they isolated endophytes that live in the inner tissues of plant stems and screened them for their ability to degrade polyurethane. "Several active organisms were identified, including two distinct isolates of Pestalotiopsis microspora with the ability to efficiently degrade and utilize PUR as the sole carbon source when grown anaerobically."

They further added "each of the more than 300000 land plant species on earth potentially hosts multiple endhophyte species." So further exploration of of properties of endophytes could potentially reveal many more properties and perhaps the ability to degrade other plastic compounds. Endophytes reach their greatest diversity in tropical rainforests. So it is imperative that we protect our tropical rainforests so that at sometime in future mankind may discover potential saviours in form of these endophytes who can help in removing the pollution that we are causing.
