Pretty sure they meant to reply to another image in the thread here but messed it up.

Yes, if taking it seriously, then those are reasonable conclusions. However, I think you’re just overthinking it, in this context the scenario exists to service the joke rather than the other way around.

The comedic implication is that the giant eagles are natural predators of goblins and, more importantly, hobbits. And might be inclined to a mid-flight snack.

Well, we know that they’re typically referred to as male (as far as I know at least), so perhaps they’re all transmasc?

I thought that part of it at least was that much like existing life has a harder time breaking down these mirror proteins the same is true in reverse. So any life that was mirror protein based would struggle with consuming and gaining energy. As such the current protein chirality basically won by being first to market. That being said I don’t see why that would hamper reverse chirality photosynthesis, and I don’t really know what I’m talking about so perhaps your suggestion is more convincing after all.

Yes and no. I can’t speak to the particulars of this situation but differences in means matter even if they currently produce the same outcome. A toothless dog and a dog in a muzzle are different in important ways.

I entirely agree, and that does sound like a good approach. I just caution against presenting recycling as a solution rather than as a reduction of harm.

You often can’t though unfortunately. Most plastics can only be recycled a handful of times before they degrade too far. Recycling, while better than nothing, is a far more inefficient and flawed process than it is often presented as. That’s why it is far better to reduce usage in the first place and reuse things as is where you can. Of course this is all still easier said than done.
