When I was visiting Europe, seeing all the trees so well integrated into urban areas was so nice.

Then we git our flight back to Toronto. Concrete jungle.

These algae also produce biogas that can be used for heating or producing electricity.

Damn if only trees created something gaseous that was useful

[–] AlolanYoda@mander.xyz 4 points 6 months ago

They emit carbon dioxide, a greenhouse gas, and oxygen, which causes rust in metals and aging in humans. So it's a negative really...

I guess it would take a lot of time to accommodate Mars for trees. More than for algae ;)

Can't they just put the algae in the ocean?

There are algae in the ocean. The problem with ocean algae is not that they aren't there, but that their requirements (sunlight, oxygen, acidity, temperature, etc.) prevent them from expanding any further.

Trees arent liquid

What happens when one of these breaks and drains into the sewer system? Algae blooms cause noxious odors and would proliferate quickly in the nitrogen-rich environment of human waste water, potentially building up as clogs in the sewer lines. And if the system drains into a natural body of water, the algae can have devastating toxic effects on the natural wildlife. If it doesn't drain and instead gets recycled, then the water treatment process becomes much more difficult and expensive.
