Take a moment and ask yourself, a project like this requires a lot of time, money and dedication of resources, why would scientists dedicate that time to something that could just be done by a tree?

The answer is they wouldn't. So that means this claim requires further investigation!

This project is called LIQUID 3, and it's not meant for cities with wide open spaces, it's meant for cities like Belgrade in Serbia. These cities are densely populated and heavily polluted, to the point where pollution actually chokes out current trees and makes creating green spaces difficult.

Liquid 3 was a PhD scientists answer to these problems. The microalgae tank is intended for spaces where you either:

Don't have enough space to plant full trees, or

Don't have enough time to plant trees and wait for them to grow up.

The tank is extremely efficient when you consider the amount of space needed compared to the amount of CO2 turned into oxygen. The tank can operate throughout the winter. And most importantly, it can be quickly set up in areas that desperately need relief from air pollution NOW not in 10 years when trees are done growing. Children currently suffocating on polluted air can't wait for trees to grow, they need to be taken care of now, and Liquid 3 is one of the ways to take care of them. Depending on the species of microalgea used, a number have shown a pretty amazing capacity to pull heavy metals out of the air which is something trees can get choked up by.

The tanks aren't just tanks either! Liquid 3 have solar panels placed on top, they have lighting and mobile phone charging, and they work as public benches. The designers of it want to encourage green spaces where there's room, but where there isn't room or time, Liquid 3 can step in. Realistically, this isn't a replacement for trees. It's replacing boring metal city benches with new, cooler benches that also clean the air (and have at least some heating during the winter).

Not only that, but the microalgea that grows is native to Serbia and all that microalgea has a ton of great uses! It makes for great fertilizer, compost, wastewater treatment, cleaner biofuels and even for helping create new tanks for further air purification. They only require a quick algae divide once a month, and the produced algae can be carted off to where ever it's needed. This makes them effective solutions for areas that can't sustain complex installations.

“And we loved it, we were all having a great time, but then he saw my sister and I, and he just got this - this look in his eyes, and then-”

She hesitated, worrying the coarse material between her fingers. “Things got pretty bad after that,” she muttered. “I know it’s silly, but I try to keep - her - comfortable. We don’t know if she can still hear us, or see us, or if she’s even still in here, but I like to think she is. I talk to her when I can, I leave music on when I’m out of the house. I tried to convince my parents to bring her with us when we went to Disneyland, but they didn’t - didn’t really take that well.”

see, you wouldn't necessarily pick up on this, but beluga skulls (and most cetacean skulls in general) are pretty much

flat...

so what's going on up there? well, most of the beluga's head is taken up by soft tissue and a large organ called the melon, which is basically a big ol waterballoon of semiliquid fat!

(boob. it's a head boob.)

this organ is found in every toothed whale and dolphin species on the planet and it's INCREDIBLY important, because the melon is what lets them echolocate!

the actual sound-producing organ is inside their nasal passage of all places, which sits up behind there, but the melon is what's actually used to fine-tune the soundwaves into the laser-accurate pinpoints that dolphins and toothed whales are so famous for.

I was reading one story where the apocalypse was impossibly-rising oceans. Like, water is appearing from *waves hand* the Earth's crust or something, and literally all dry surface land on Earth is going to become underwater in X years. Part of the story was about a giant research project to invent FTL to send a few hundred humans to a nearby star which might have a habitable planet. You know what they were hoping to find? A planet with liquid water. Their plan was to descend from their starship and restart civilization using just the tools they brought with them, on a world with no life and no breathable air and the wrong gravity and the wrong temperate and the wrong sunlight and the wrong day-night cycle, just because it had liquid water. You know where else has liquid water? The flooded Earth you just abandoned. Instead of researching starship technology, you could have spent that time loading up all the same civilization-restarter tools into boats.
