I dont even know where to to start with the math, but I always wondered if there is not a viable carbon capture business in just growing and burying plants.

Get some fast growing plant like Japanese Knotweed or bamboo, grow it out for a year, harvest and dump the biomass into a decomissioned mineshaft to minimize contact with the atmosphere. Rinse and repeat.

Nope. Philip Mason debunked #TeamTrees as yet another, completely pointless MrBeast vibe cause.

Better off with bio-CSS using GMO kelp or algae, e.g., biomass that grows faster and doesn't rot or burn.

I don't know what #TeamTrees is, nor do I know what MrBeast's involvement in it is. I only know _of_ MrBeast because of some workplace controversy that spilled on to the general internet recently.

I also did not specifically say trees need to be used. I mentioned fast growing things like bamboo. If there is another biological organism (GMO or not) that accumulates carbon-rich biomass faster, then I'm interested in understanding how that compares to more modern CCS techniques that require electricity for example.

You have a good idea. Ignore the armchair idiots. Another take on this idea is using plankton that has been seeded with iron.
