A Cheap, Low-Tech Solution for Storing Carbon? Researchers Suggest Burying Wood

To turn trees into lumber you have to cut them down, transport them to a sawmill, cut them to size, kiln dry them, transport them to the build site, build a house out of it, etc.

Underground sequestration has no transport, milling or kiln costs. Just cut down a bunch of trees, dig a trench where the trees used to be, and bury the trunks.

Why not both?

Too obvious!
