Is the blobfish involved?
Regression of muscle osmolality on depth of teleosts. No accepted reports of teleost fishes exist below about 8,000 meters. Yancey et al. 2014 theorize this is because the osmolyte trimethylamine oxide, which protects enzyme kinetics and structure from hydrostatic pressure, is predicted to reach a concentration beyond 8,200 meters which would make the fish hypertonic, presumably killing it (most marine fishes have inactive glomeruli or lack them entirely).

The deep ocean is connected to global geochemical cycles. For instance subseafloor sediments are the largest near-surface carbon reservoir on earth. Also, bacteria that respire by reducing sulfate comprise a majority of the microbial community in anoxic seafloor sediments, and the precipitation of this reduced sulfate affects ocean alkalinity, as well as the partial pressure of carbon dioxide in the atmosphere.
generally speaking, if literally anything goes extinct, it can and WILL ripple out in some fashion or other.
humans being omnivores means that were probably better suited than most to deal with such things
but its more about how it would effect the rest of the foodchain, which could be very drastic
less biodiversity is pretty much universally a very bad thing.
and the further down the foodchain such extinctions happen, the greater potential they have to be absolutely catastrophic
idk enough about sealife to really comment too much more and frankly neither does anyone else due to how hard it is to explore the deeper parts of the ocean but i reckon it would cause serious problems for us down the line
im always miffed about how much attention goes into things, like global warming which thanks to volcanoes, solar flares, and other naturally occurring phenomena (not to mention third world industrialization, which absolutely WILL NOT STOP, as first world corporations depends on their cheap bullshit and psuedo-slave labor), would be very difficult for us to really control too terribly much, meanwhile were still absolutely loading the ocean with shitty plastic bags and trash, which have absolutely devastated the oceans gyres.
imo thats much more of an addressable issue, and likely has much more of an impact on the actual health of the global ecosystem.
life on earth has shown to be quite capable at adapting to changes in temperature over its history. but loading the main breeding grounds for nearly all ocean life with shitty non-biodegradable plastic and other industrial pollution? well, we really have no data points to reference what will happen in that instance.
bet its no good tho
but alas, lobbying against the petroleum industry in such a fashion is pretty much out of the question
