I'm way more afraid of the humans that want to drain and eradicate the native population of the Everglades!

Even putting aside that it destroys incredible natural beauty for land that's not even productively useful, it astounds me that people still buy into major terraforming projects. Every single time it's had absolutely horrendous consequences often with millions of human deaths attached. Don't make large changes to chaotic systems!

Ah, yes, terrible consequences, such as, the irrigation and suitability for farmland of central California, the lack of frequent flooding of the Mississippi river and tributaries and the present dryness of the Netherlands.

I don't think draining the everglades is tractable and I think it's more valuable as is since you're not gonna out farm the midwest. But it's really easy to be on a high horse and not appreciate the successful projects that we benefit from the results of.

It does not take much familiarity with the history of Mississippi flood control and the Army Corps of Engineers to realize how risky, fraught, and short-sighted the whole project has been. The delta's dying and the Old River Control Structure is one bad day away from diverting the entire river to the Atchafalaya.

_The Great River_ by Boyce Upholt from last year is a good place to start learning about the Mississippi.

Or John McPhee's "Atchafalaya".

> the irrigation and suitability for farmland of central California

The unsustainable irrigation that's draining aquifers during droughts and causing permanent damage[1] to groundwater retention? The irrigation that's causing changes in land topography[2]?

> the lack of frequent flooding of the Mississippi river

You mean the system which is a well known ecological disaster?[3][4][5]

And no frequent flooding? Since 2017, the Mississippi River Corridor Critical Area (which covers only a small portion of the watershed) has seen the USDA pay out $11.4 billion[6] to cover damages from flooding. I live in the watershed and for most of the summer I get flood alerts every time it rains. Damages are on the news constantly. In 2008, a tributary river flooded so badly it destroyed two mid-sized cities in Iowa[7]. Then you have the the 2011 flooding[8] of the Mississippi which was the most disastrous since before most modifications had been made to the river. Lack of frequent flooding? Just because you don't hear about it doesn't mean it's not happening.

Like what are we talking about here? Even reaching for what you assume to be innocuous examples, empirically observable negative consequences hang off of them like fruiting bodies. Who knows what the consequences will look like in 100-200 years when they've had time to iteratively feed back into themselves.

This is exactly the sort of ignorant of the past viewpoint I was complaining about.

The part of CA we're talking about was a desert shithole before (arguably still is). There's debate about just how much we can sustainably irrigate it, but at least we can irrigate it. The alternative is basically no agricultural activity. Maybe some grazing.

Ditto for the Mississippi. It floods "a little" now vs "somewhere on it is getting wiped out just about every year" before. If it's only happening once a decade now that's a huge improvement. You can mislead all you want by saying things like "worst since X" and whatnot but the fact of the matter is that the system clearly works ok if most of the Xs are from before the system was there.

The material wealth generated by the economic activity enabled by these two projects is almost impossible to quantify.

I think it speaks volumes that you didn't even attempt to address my 3rd example.

You talking about the Imperial Valley or the Central Valley? The former is naturally desert, the latter was naturally abundant in wetlands and flood-prone grasslands, before agriculture took over.

https://en.wikipedia.org/wiki/Salton_Trough

It sounds like you're talking about the Imperial Valley, which is a different ball of wax from the whole wetland-draining argument here.

I object to "desert shithole" --- the Sonoran Desert is an ecosystem worthy of value in its own right, we just don't benefit from it as humans unless we turn to resource extraction or agriculture.

		You're right I misspoke. I'm talking about the Imperial valley.

Although I think it's best for nature to leave things how they are, draining the Landes in France (a swampy area comparable to that of the Everglades) and replacing it with a pine forest only had positive impacts on the humans living there (if only because it was a major step towards eradicating malaria in France).

To be honest though, it was originally a forest, and had turned into a swamp after being deforested by humans in the early middle ages.

I generally agree though I have to say I’ve been impressed by China’s efforts to reduce desertification. It’s not perfect, but they seem to have an evolving strategy and the right priorities.
