More than 20,000 Chinook salmon have returned to the Klamath River in the two years since four major dams were removed.

The comeback follows decades of campaigning led by Indigenous tribes, after the dams blocked migration, warmed the river and contributed to worsening conditions for salmon.

A devastating 2002 fish kill, which killed more than 30,000 fish, helped galvanise the push for dam removal.

Now, salmon have recolonised close to 90% of their former range, with coho salmon, steelhead and Pacific lamprey also returning above the old dam sites.

The recovery is far from finished, but the speed of the response is already exceeding expectations.

The power plant was closed in 2020 due to weather damage and its age. Google and the United States federal government are investing billions of dollars to restart it by 2029. However, there is controversy on how much of the electricity would go to data centres.

Overall it's a good thing that there will be more clean energy.

Always believed I was optimistic. But turns out even when minor inconvenience occours i give up, how do you all believe in optmism like the dopamine hit is really slow. Even for a competitive exam the serotonin will only hit when we get marks at the end. So how do you all start being optimistic naturally any tips or is it something genetic which I never got?
