The only example I can think of is water. While it's not gone, the quality and cleanliness has decreased over time. There are many areas where you can no longer consume seafood due to high pollution levels. Same with swimming or drinking (boiling used to be sufficient to clean water, but it certainly isn't anymore).

Even "safe" seafood is only recommended to be consumed 2 times a week now due to the build up of heavy metals.

It's also true that we'll always been able to purify water for consumption/use, but there is a cost to that and I don't see that cost decreasing.

Not safe to consume seafood? As long as it's alive, you can eat it.

Maybe it lowers your lifespan. That's not that big of a problem, humans have lived like that for the vast majority of their existence.

As for water, it's everywhere. Obviously, some people can run out of it, but then again a minority is always fucked in this world.

> As for water, it's everywhere.

The vast majority of it is seawater, which humans can't drink because of its salt content. There's still enough freshwater in most places, but the regions where drinkable water scarcity is a problem are growing larger every year.

Desalination plants do exist, but it's up to 10x more expensive in most places (in California it's only about 2x more expensive because water is already pretty scarce there) and it's also not great for the environment either:

"The problem is that the desalination of water requires a lot of energy. Salt dissolves very easily in water, forming strong chemical bonds, and those bonds are difficult to break. Energy and the technology to desalinate water are both expensive, and this means that desalinating water can be pretty costly...It can cost from just under $1 to well over $2 to produce one cubic meter (264 gallons) of desalted water from the ocean...But switch the source to a river or an aquifer, and the cost of a cubic meter of water can plummet to 10 to 20 cents, and farmers often pay far less."

"There are environmental costs of desalination, as well. Sea life can get sucked into desalination plants, killing small ocean creatures like baby fish and plankton, upsetting the food chain. Also, there's the problem of what to do with the separated salt, which is left over as a very concentrated brine. Pumping this supersalty water back into the ocean can harm local aquatic life. Reducing these impacts is possible, but it adds to the costs.'"

Saltwater, meet sun and remineralization.

And really, $1 is too expensive? How much do you need? I use ~10m3/month during summer for myself and a small garden.

If you use more, well, [thread title]. Smh, talking about resources running out and changing lifestyle.

But yeah, those further inland will have more trouble.

You use far more than that. The vast majority of water you “consume” is in the production of the food you eat, especially meat.

[jotm]

Oh yeah, you're right. I completely forgot.

I'm interested in what you're saying, I think, I wish it was clear and unambiguous so I could understand it.
