Lots of folks like to talk about collapse. There are movies made about the different ways it might happen.
I want to see one in the very conceivable world where bacteria evolve to eat plastic. All plastic. Rapidly.
What would all the plastic turning to dust before we're ready for it do to the world?
Buildings collapsing or no longer being weather proof. Cars failing. Most of the electrical grid is down because the insulation sloughed off all the wires. Everything mechanical seizes up because the synthetic lubricants are so similar to plastic they are consumed too. Hospitals and sterilization are impossible.
