Trees offer real world benefits of carbon reduction, temperature reduction, shade for people, the psychological benefits that trees offer, some limited wildlife habitat, and they do it without much outside help. They grow themselves with decent maintenance.

But you have to build and maintain this tank. What carbon was used to do so, and what maintenance will it need. Can it offset its own cost? It offers no benefits to wildlife, no shade, no temperature reduction.

Yeah, trees leave leaf litter and can heave sidewalks with roots, but given that neither system is perfect, there’s no reason to argue that boxes of algae are better.

Why do we need to argue which is better? In some places, beautification isn't really practical, but you can still stick these around. They don't look hard to install or uninstall, unlike trees.

I would hate to see a tree actually replaced by one these. But no one but the meme is saying that is the plan.

I think we have reached the limit for how much we should "improve" and replace nature, if there's no room for trees we should make room instead of accomodating yet another industrial solution to a problem created by industry in the first place.

We're going in the wrong direction.

Algae is actually much better at capturing carbon than trees are.

We are just fine with the trees though, thanks.

So you're a climate change denier? You don't think we need to worry about co2 levels?

Or is this just a knee jerk unthought responce because you hate science and technology?

[–] EatYouWell@lemmy.world 2 points 11 months ago

Except we aren't. And trees are awful for urban areas from an infrastructure standpoint.

carbon reduction

Mostly indirect.

Also trees dampen noise

Can it offset its own cost?

I guess.

there’s no reason to argue that boxes of algae are better.

Depends on metric of choice. Still I would prefer trees.
