What would be the point of that? Why not just cut down the trees, bury them and grow new ones?

If you simply bury them, there is a good chance the wood will be decomposed anaerobically, producing methane then carbon dioxide.

Why bury them? Build more things from wood instead of plastic.

That would be nice wouldn't it.

I think the point is that by removing the water, empty space and non-carbon it would be physically much smaller.

Now, compress it under great pressure and heat and enter the Diamond Age.

Then we can pour diamonds into our cars and burn them...

Per the article, the details of that will be released next week. Seems like a cool idea.
