Nobody here is an idiot. We know this "crisis" isn't new, but it has been getting more press lately. Why? I don't know, I'm certain someone is making a buck on it. However, I'm glad it's getting press because it's something we can visibly see both the damage, and what our help would do to it. Since humans are visual creatures, that's important.
One big issue is that we're over fishing the fuck out of everything. Hell, watch The Deadliest Catch and you'll see the effects in action as their fishing grounds have dried up over the years.
It's honestly simple math and science. All living things are dependent upon one another. When you harvest millions of pounds of a species (or multiple species) each day, week, month, or year it's unsustainable unless the remaining ones are multiplying faster than you're removing them. So when you fish or hunt something to extinction, not only have you just removed something off your menu, but you negatively affected nature in some way.
For example: Removing predators of Sea Urchins results in "urchin barrens". Removing predators near the Great Barrier Reef has resulted in the population of starfish skyrocketing and damaging the reef.

That's a tough ask because you're pretty critical of most outlets. It's a good quality to have, particularly in this day and age of the MSM hyping and inventing stories. Is there an outlet you would accept as a good source? If so, I'll see what I can do about finding a story or two from there on this subject.
You can do an experiment at home to see the reality though. Go get an aquarium. Follow all instructions and buy a perfect blend of fish and plants that will help to maintain the tank. You'll get a nice balance of different species living together and each contributing to the overall health of the tank.
Now remove the plecostomus. Make note of what happens to the health of the tank and the other fish.
OR add a bunch more of one species to the point of overpopulation and see what happens.
OR paint your room without turning off their filter and watch their skin strip off.
Or just think about how quickly the fish in your tank would need to reproduce if they were your only source of food.
Etc.
You might think an aquarium doesn't equal the entire planet, but it does, just at a much lesser scale. Thus, things happen quicker.
I think we all can agree that if we continue to over fish and wipe out the salmon, tuna, groupers, sea bass, whales,lobsters, crabs, etc. that means that other fish, animals, and plants that depend on them will also suffer. I know fisheries are a thing, but they have their own negatives that come with them in relation to the ocean.
Notice I haven't even yet talked about the effects of plastic and other pollution. Those are completely separate issues, but all are doing their part in fucking the oceans up.
I agree with you that the climate change issue has definitely suffered from a lot of bad science, bad takes, bad politics, and so on, causing skeptics to have some legitimate questions. I would ask you to buy into the oceans being in trouble.
