To avoid ending up living on mountains of waste, everything will need to be recyclable and ultimately biodegradable.
In a world with limited resources, one can fulfill the limitless needs of human beings through an endless recycling of those resources.
Bio-technologies will need to be developed to provide all the biologically engineered components or materials that are required by our manufacturing industry to make products that will quickly disintegrate after usage via the recycling process of Nature.
Everything could be made biologically or could at least be biologically assimilated.
