In the mid 20th century, whole cities’ sewage systems safely and successfully used fish to treat and purify their water. Waste-fed fish ponds are a low-tech, cheap, and sustainable alternative to deal with our own shit — and to obtain high protein food in the process.

Each reason points to a deeper problem: our economy’s inability to value the right things.

This is a fascinating article about a low-tech solution to alleviate some of our climate problems, but with a depressing ending. Political leaders, technologists, and capitalism itself don't value technologies that aren't flashy or are developed and iterated on by native peoples.

It reminds me of my own field, web development, where people are drawn to highly engineered, flashy toolchains instead of working with the systems that is already present (browsers, HTML, DOM APIs, etc). I think the author is right that people want the solution to be separate from the base system. People like the idea of starting from scratch to try to control all the variables, instead of working around issues with creative solutions.
