Besides being created using non-renewable petroleum products, the pollution caused from plastic waste is causing massive, negative consequences on ecosystems.
I've posted before about efforts to clean up the plastic waste that has accumulated in the oceans:
The Monkey Buddha:
There are other solutions being studied & implemented to help address this serious problem that we are leaving for future generations.
One answer is to develop biodegradable packaging made from plant fibers.
Scientists are also looking into creating packaging materials made from compacted fungus mycelia.
Another way to help eliminate existing plastic waste is to use bacteria or other organisms that actually consume plastic materials.
I believe that human ingenuity can solve almost any problem that human greed and short-sightedness can create. We just need the drive and creative thinking to make it happen.
