True, but at least it's not single use. Is there a viable alternative? A non-petrochemical plastic that has the same qualities? It's not like they can whittle them out of wood or cast them with metal so it'll always be some form of polymer, and I'm sure they would jump at a more ecologically sound option.

Lego has been testing making some pieces out of corn-based plastic or other natural plastics. https://www.lego.com/en-us/sustainability/sustainable-materi...

Some of the first forays resulted in notably lower-quality bricks.

lego compatible bricks made from wood do exist. they probably don't last as long though.

I'm sure they don't unless made from a stable hardwood or coated somehow to resist expansion/contraction which would defeat the whole point of using a sustainable material. Lovely idea though, I really like wooden objects.
