Plastic is not a climate problem. Ocean pollution is mainly fishing nets. There is a garbage problem that automation can help with recycling. Making fishing nets out of cotton instead of nylon would be a big improvment.

Wood and paper is a renewable resource that could be used more. Global warming is especially a threat to vast northern forests with fire that are paper sources, while also permitting more/bigger tree growth in the regions. Harvesting trees is a solution to fires, and more demand an incentive to prevent fires.

Manufacturing with compressed sawdust could be a cost competitive alternative to plastic, but the binder could make the wood product less recyclable.
