Trees do this.

More trees please.

Why don't we just plant trees ⬇️

I never said plant trees. Any environmentalists knows that preserving old trees is more impactful than planting new ones.
LouSanous t1_j1fj6bp wrote
That's not entirely true. While old large trees represent significant stores of carbon, forests that are early in their maturity absorb more carbon from the air. As they get older, they reach a steady state where the decomposition of old material reaches relative parity with the atmospheric absorption for new material.

And any environmentalist knows one of the best ways to combat greenhouse gases is to inhale your own farts. Though, tragically, I hear pretentiousness is a common side effect. 😔

Trees also decompose or burn releasing the CO2 they captured.

Victim blaming trees now?

This what causes them to turn on this according to M Night Shyamalan’s documentary “The Happening”.

Post on r/climatechange on an article in Nature from this past week shows that trees removed much less carbon than originally believed - other plants were more responsible, and CO2 levels were much lower than previously believed.

Efficient? Planting trees and keeping them alive is hard. Soil quality isnt the best in many places either.

Are you kidding me?? Trees grow on their own without any need for human assistance and have for roughly 400 million years.

If we want to reverse global warming we will have to plant trees and manage these forests. And that is not easy.
Some data:
The mean survival rate computed on a sample of agroforestry private trees was 51% while on public trees it was 30%. In woodlots and forest plantations, private trees survived at 65% while the public ones survived at 40%.
On average, about half of trees planted in tropical and sub-tropical forest restoration efforts do not survive more than five years.
Tropical rain forests at some point can no longer sustain themselves either. It's delicate.

They aren't that great at doing it at the point of production.
Wouldn't it be awesome to have a tree-like thing that just turned the output of a car or power plant into ... I dunno, construction materials or something, without any extra CO2 going anywhere else?

Hemp captures more carbon (aids in drawdown) than trees do. Plus, hemp performs better when compared to trees in bioremediation of the soil.
Using hemp into OSB or hempcrete further commits to drawdown as alternatives to current products that wouldn’t otherwise test as well on an ecologically friendly level. Especially for how widely we use wood, plastic, formaldehyde, and petrochemicals in construction hemp offers us a far more superior product in build and preventing off gassing down the road.
