There is something I find a bit confusing with the idea that we should find ways of degrading plastics. Our big concern right now is climate change, and it is in large part driven by CO2 emissions. Plastic is sequestrated carbon, degrading plastic means finding life forms that turn plastic into CO2. Why do that when we are trying so hard to avoid putting more CO2 in the atmosphere. And should we want do destroy that plastic, we can burn it in furnaces and use that energy for ourselves. As expected, the article mentions unproperly disposed plastic that ends up where it shouldn't be. Plastic-eating mushrooms won't solve that problem unless they work and spread in the wild, which is highly unlikely: these solution usually require very specific conditions. For example PLA is technically biodegradable, but unless you are using an industrial compost plant, it won't. And if these mushrooms work in the wild, we will have a bigger problem...
