With time evolution will widen the conditions, with how much plastic is in the environment.
But wood and paper are also readily biodegrade, and yet by simply by controlling the amount of moisture present we manage to make those last a long, long time. In addition we have treatment options to delay decomposition even in wet conditions.
Wood is often protected by plastics. Acrylic wood finish and paint are plastic. Particle boards such as those in many Ikea furniture are covered with a plastic sheet.
If you don't use plastic you need to switch to solutions requiring more maintenance and offering less protection like vegetable oil or pine tar.
