Less infrastructure erosion from roots? Integration into places like above ground parking spaces? Hell could you imagine integrating them into bridge underpasses or walk ways? Heck make a semi destructible version and use that for crash bollards. Only a level 5 vegan is going to complain if some allege is spilt.

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

Trees arent liquid

"Why do you say this is stupid? You're so negative." Run of the mill conformist toxic optimist tech bro dildo

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

"What's wrong with trees" ask people who have never had an allergy or thought about what roots do to all those nice expensive foundations

Your just thinking outside the box!
