We found a genius way to revive a poisoned river [video]

For me, bioremediation is sci-fi made real. It was all hypothetical back in the 90s. (I was volunteering at an org trying to save PNW salmon from extinction.)

Developers were being allowed to pave critical habitat in exchange for creating "wetlands" somewhere else. But no one knew how to do that. And many were skeptical it could even be done.

So important.

Same info pulled from the accompanying article https://planetwild.com/blog/how-were-reviving-a-poisoned-riv...

"By filling up the river bed with a specific kind of gravel, multiple things happen... [ new breeding grounds, water cleansing, oxygenation, natural overflow, new habitats]"

One tidbit I learned about PNW salmon is that all the varieties need very specific conditions, like the kind of gravel, to successfully reproduce.

It's makes me so frikkin happy to learn that people are now routinely doing stuff we only dreamed about just a few decades ago.

Even the orientation of furrows helps. Not having them perpendicular to the river the furrows should be parallel.

Even provincial workers cutting trees need to use canola oil for bar oil (bar and the saw chain lubrication).

Farms can have runoff of fertilizer and it can cause fish to die rapidly in large groups aka a "fishkill". The farmer is fined too.

I think this has more to do with flood plain management. Some countries prohibit construction within X meters of the average water level because that's expectedly where water will rise. In some shallow areas municipalities even build parks with no permanent structure because of the high probability those areas will be flooded, and that ensures no life is put at risk and economic damage is limited to whatever infrastructure was placed there (i.e., park benches, public restroom, small public cafe, camping ground, etc.)

"genius" and "ingenious" are both super weird for describing own idea. Not grammatically wrong but still wrong. Like if you refer to your own post as "my genius article" I'd assume you are being self deprecating and if not I might start wondering if you're OK. Even if I thought your article was actually genius.

Pick anything, promising, practical, and you know for me personally simply "a way" to "revive" a river would sound awesome because I knew zero of those until now.
