Time scale is also something I want to know about. "Can I remove CO2 from the air and turn it into something valuable in a way that is cost effective?" is one question. Another question is, "Can I remove CO2 from the air and turn it into something valuable faster than a tree?"

In some climate zones, grasslands do it better than forests.

A tree gives you wood. What are the valuable outputs of grasslands?

Does bamboo count?

You can make it into a carbon-neutral heating fuel.

You can make paper products including things like cardboard and packaging.

You can put livestock on it and produce meat.

Or if you just want to sequester carbon, you can harvest it and bury it deep in the ground.

If you use grasslands for grazing cattle you get meat, or also wool with sheep. Sequestering carbon into grassland soil (or into any soil, really) makes them better at absorbing and retaining rainwater, reducing the risks of catastrophic floods in the watershed area.

Grass always do it better than trees.

And the GP is quite wrong, because almost everything will be more efficient than trees or grass. Machines are just way more expensive, that's why nobody ever made them.

What is smarter, spending years researching and arguing the best way to do this, or using the natural process all over, and adapting the best practice locally, to try to solve climate change?

Some places can plant trees, others grasslands. Or whatever, but it seems like there is a lot of money to create an industrial process that can be commercialized instead of just doing the work naturally...

Maybe. I know it actually is grass, but are bamboo growths called grasslands?

Good points. I wasn't thinking of second order products.
