I wonder if huge shifts to indoor / tower / hydroponic farming would help to mitigate some of the water losses. Also reducing our dependency on meat / dairy, as they seem to be fairly water dependent.

There have to be options, as we can't just stop producing food; but I'm sure we could change our practices and reduce waste water by a large margin.

Sure. Our perceptions and mental states are probably going to be subject to tons of technological "tuning". Who knows what that's going to look like

This is all spitballing / conjecture obviously

Why is everything suddenly a crisis and in need of “urgent” fixing?!

It’s quite ridiculous that there is absolutely no oversight whatsoever for commercial use of natural resources in the beginning and then 20, 30, 100 years later “we” need to fix it! “We” didn’t break it so why “we” need to fix it.

The people who broke it need to fix it, so send the alarm bells directly to them.

Good question. One definition could be something like: what is the most computationally difficult task your species can solve? (and we can barrow from some metrics from computer science to define task difficulty)

The key here is: I think the problems we see with the world aren't the result of humans being "unintelligent" (possibly similar to u/StarChild413's point about sapience -vs- wisdom).

I think if an alien species visited earth and watched us, their conclusion wouldn't be: "wow, look at these idiots". Rather, I think it would be: "oh, that makes sense that they're doing that, given millions of years of evolution in competitive, resource scarce environments + the computational problem of resource allocation with a species that large".

No, the sound example shows how the universe is fined tuned for life.

Sound isnt sound until puffs of air meet our eardrum. It’s a pretty straight forward concept: Prior to meeting an ear drum, sound is rapid little puffs of air and when those little puffs of air meet an ear drum, then we have what is known as sound.

What’s the difference between 40 and 30 hz? Nothing except one produces an experience of sound inside of our minds and other does not. If there is no ear, there is no sound, only puffs of air.

The observer effect is a well documented phenomenon https://www.scienceabc.com/pure-sciences/observer-effect-quantum-mechanics.html

Whether I understand the nuances of the experiment is irrelevant to understanding the concept, so my bad, I didn’t mean to caught up in a discussion on that but I have yet to see anything that debunk the observer effect.

Nobody is suggesting that the quoted cost is to build a reactor on the moon. The money is to make and demonstrate a prototype on Earth.

This makes the most sense and the easiest path.

I hate when articles don't make sense and the writer/reporter can't be bothered to clarify.

You literally couldn't put a photograph of a nuclear reactor on the moon for that.

I would prioritize the agricultural reforms over desalination. Not that we don’t need to do both, but desalination by itself is going to mask the problem and introduce additional environmental costs.

We're like the frog in the pot of water that increasingly gets hotter. We'll all be boiled alive one day.

completely agree but the way most governments work around the world is they won't build anything till people start dying...this stuff should have been built years ago and they can use wave/offshore wind to power it

We monkeys do not react to dangers unless it's on our face. This is what will happen.
