What makes it even more ridiculous is that one could think grown fish are a fine solution over-fishing.

But it turns out, many fish farms use caught fish for (part of) the fishmeal and fish oil used to feed the fish they grow. Because many fish we eat turn out to be pescetarian.

Ocean acidification is much more complex than "less algae and less fish." In fact some algae and bacteria will have giant blooms partly as a result of that, warming, and Nitrogenous runoff. Giant blooms consume oxygen in the primary marine trophic levels, causing die-offs that liberate more nutrients, leading to hypoxic and even large anoxic zones. You also have the concern that acifification can lead to (at first) worse outcomes for organisms depending on carbonates, and eventually (potentially) their extinction.

All of this assumes that we have a pretty solid understanding of what this system looks like as we wrench it from one feedback loop into another, but it's the best we've got.

The problem is we have no way to pass a global carbon tax, and the way the global economy works now any attempts at a national level will only succeed in moving the carbon generation to other countries.

In Germany we tried that, politicians like that got very strong mandate to lower emissions.

First we tried diesel gate.

Then someone had amazing idea to import Russian gas.

Now we are catching and taxing cow farts! Maybe bio methane could generate electricity!!!

The problem is multifaceted, because we're not only aren't told the truth, we are told lies that make things even worse, and people seem to like those.

For example, overpopulation has been a concern for many decades, yet politicians that ignore the problem, or actually advocate for more population, somehow keep getting elected. Either democracy has broken beyond repair, or humanity averages to dumb. I'm inclined to the latter, because I believe that every individual, even if they can do smart things, is very dumb in other things.

Given that the politicians are making a billion dollars on crypto scams, being gifted multimillion-dollar airplanes, and recipients of gold crowns, I’ll eat whatever I want regardless of who is elected.

The truth is that if we weren’t burdened with multi billionaires, we would have plenty of everything.
