We are making everything with the wrong materials! Kenaf is better than trees for making paper. Flax and hemp are better than cotton for making clothing. Cork and flax (linoleum) make better flooring than vinyl or laminate. Wheat husks and sunflowers hulls make better cabinets than conventional particleboard.
Buckwheat and latex make better pillows and bedding than synthetics.
Organic wool makes better outerwear than synthetics.
Rapeseed makes better fuel than petroleum.
Starch from any number of plants makes better plastic than petroleum.
(Also native plants, properly investigated and grown may replace any of the above, e.g. the Land Institute.)
