Excerpt from this story from EcoWatch:
From coral bleaching to ocean acidification, there is lots of discussion about how the climate crisis harms marine life. But is it possible that the loss of undersea animals could actually worsen the impacts of climate change?
A study published in Science Advances last year found that the amount of carbon sequestered as fish dung in the ocean had declined by nearly half since commercial fishing began in earnest a little more than a century ago.
“It’s sort of demonstrating that fish matter for the big carbon cycle in the ocean and other biogeochemical cycles,” study lead author and University of California, Los Angeles oceanographer Daniele Bianchi told EcoWatch.
Fish and the Carbon Cycle
The carbon cycle describes how carbon travels from the atmosphere to plants to animals and the soil and back into the atmosphere when animals exhale (or when humans burn fossil fuels), according to the University Corporation for Atmospheric Research. In the oceans, a similar process occurs with phytoplankton, which convert carbon dioxide into the sugars that form the basis of the marine food web, according to the Woods Hole Oceanographic Institute. This carbon ends up sequestered in the deep ocean or the seafloor when animals die and sink.
Carbon dioxide is also traded back and forth between surface water and the air. However, when considering the living drivers of this and other biochemical processes in the ocean, scientists have largely looked at phytoplankton or bacteria rather than animals like fish, Bianchi said. This study marks “the first time that I think someone [has tried] to do these calculations and show that biological processes that have to do with animals in the ocean matter for these chemical processes,” he said.

could you stop acting rude and pedantic it’s just tumblr it ain’t that serious lol
If you can't be specific I can't really do anything. Consider blocking me instead! Blocking people is fucking awesome.

It's good for my fish stress levels probably, but in principle it's such a travesty that my boys are not interested in the aquarium whatsoever (except for sitting on, <3 surfaces)
Every other cat that has ever visited has been baffled, amazed, mouth open, paws out... and meanwhile they just sit their looking like bored rich children, "What, your mother didn't install a magic viewing pond at your house? Not even a little one? Sounds kinda poor"

idk if this is a hot take or not but i would literally rather everyone just throw all their insults and criticisms of me at my face. like i'd rather just know. a) so i can fix the problems and b) because the not knowing drives me bonkers (what if everyone hates me, a social anxiety story. but seriously what if everyone hates me tho--). getting notes like "sorry to bother you but this thing you've been doing has been really annoying for awhile" is legit The Worst because we could've fixed that!!! i would've tried to do better if i'd known!!! i don't ever claim to be a good person, let alone a perfect person, but i do /try/ to be better!!! (but then again no one would be /wrong/ to assume that me attempting things scarcely results in success so like)

how are the bitten snails doing? and do their eye stalks grow back or are they permanently blind now?
they're doing good ty!! tootin along
they do grow back/heal, but those aren't eye stalks like on land snails! their eyes are on little stumps at the base of those long stalks, which are actually tentacles! they use them to feel around and supplement their poor vision.
I've been watching this new (FINAL) male kribensis the last hour and despite having many opportunities to do so, he hasn't tried to bite 😬🤞
hopefully no more jumbo escargo

#40092: woxer won’t stop texting me in all caps about its incredibly bad black friday sale and it’s starting to stress me out but i want new underwear eventually, just not right now, so i can’t unsubscribe yet
Do you remember those big red bags they gave us in freshman year? They had square bases reinforced with a layer of cardboard and fabric so we could put our takeout boxes inside and not worry about them sliding open. Everything was takeout-only that year. In the fall everyone sat in big circles on the grass outside and when I arrived in the spring I would take my food home in that big red bag, my hands shoved all the way down my pockets. It snowed hard that winter. I have photos on my old phone of Mertz field turned completely white, of pockets of water in the grass that had frozen over. The brick flooring of the patio behind Willets stayed frozen for so long, you had to pick up your feet when you walked on it or you’d fall over.
The Saturday of Thanksgiving break I looked up on my way to get dinner and saw a clear blue sky. It was cold that evening, three degrees Celcius and steadily falling. Maybe the cold had scared all the clouds away. The sky yawned wide across the domed world to the other side of campus, where it was slowly turning pink. The air was still.
When I got back I watched Dan and Phil from Youtube play a horror game about really liking golf in the first floor lounge and picked at my rice. I read the last four chapters of Kakukaku Shikajika and felt my eyes water like they did every year when I read Kakukaku Shikajika. I did a handstand.
Do you remember when campus was a ghost town without ghosts and you had gotten off at the wrong stop? Looking at Google Maps on your phone you thought to yourself, this must be the wrong place. You rubbed dust from your eyes.
From year to year to year I learned to associate quiet with nothingness. We’re the ones that got here when the fire was still burning, after all. It makes sense that we didn’t know how to be people to each other, let alone ourselves. Burning and freezing and burning and freezing in each other’s dingles in Willets with too much furniture and not enough of anything else.
That winter I spilled chicken pot pie in that old red bag and forgot to clean it up. By the time I found it by sheer smell alone it was molding hard and would cost too much effort to save. So I threw it away with all the other things I didn’t need anymore.
