As we in Chicago repeat our silly tradition of dyeing the river green for St. Patrick's Day, I think it's a good time to remind people that our ancestors *reversed the flow of the river* to keep Lake Michigan, our source of drinking water, clean and safe.
And earlier, in the 1860's, the central core of the city and all of its buildings were *lifted by several feet* to allow for the installation of sewer systems which improved drainage and public health.
Remember that the next time someone says heat pumps and electrification are hard.
