Guys, it's not one or the other. We can have trees and algae tanks. Trees can still offer all of the benefits they do like shade and beauty while algae tanks can be used to increase fresh oxygen. Algae is much better at absorbing CO2 than trees and providing clean air which is a big problem in a busy city.
It is one or the other because they’ll come out of the same budget - it’s an “opportunity cost”. So if the city has $1000 to spend on either a tree or a tank, then they can’t spend the same $1000 on both items. We’d need some balance between the two.
I don’t even understand which part of the tree experience these tanks are supposed to replace. Are they really just there to pick up CO2? Because you can also plant a forest outside the city for that.
You’ll miss out on all the other tree benefits, but so you also will with these glass tanks.
It’s been proven that humans didn’t actually get most of their fresh air from the rainforest, but actually from millions of these algea in the sea… Which is actually more logical, since trees do the opposite at night, kinda undoing any advantage they made during the day… Hence why it’s said you should never put a decorative small tree or even plants in the bedroom as they can take away oxygen levels in closed rooms at night. It’s even said not to sleep under trees outside at night cause it can cause respiratory problems.
They don’t use enough oxygen over night to negate the effect as they use the carbon to grow. It’s still bad to have a lot of plants in your bedroom, but it doesn’t really matter as long as they are relatively small.
That had me go and look it up and apparently you’re right that they use part of the carbon dioxide as energy storage, but as I understand this storage eventually gets released in full when the tree dies too…
Not sure if that would be so much to balance it out again, but it does still diminish their overall effect even more…
It is just how a tree works, it gets the matter to grow from the carbon dioxide. If they are burned or they die this carbon is slowly released again, same way as coal has carbon that is stored until burning
People can grow trees. You need a lot more to make one of those contraptions. Hard to control people when they can just grow a plant to do what they need.
People tend to forget that trees have roots.
Roots cause problems with infrastructure.
Hence why when a problem arises you try to "get to the root of it".
