What exactly is 328 years of anything? Are they saying we consume X tons, and we have found 328×X tons? Or is there some sort of future consumption estimations or trend lines accounted for? Is this all functionally available, or can we only access 20 years worth of it economically and banking on future extraction improvements? With thay large of a supply I would expect economic viability of further extraction would diminish over time.

Nearly every niche community I’ve joined has essentially died due to not having the critical mass of users to support that community. Hell, even look at the large states like California or Texas: they’re communities with only a few hundred active users and maybe a couple thousand joined. Feels like the lemmy is mostly us politics, star trek, Germans, and memes.
