Sure. If I remember correctly in Belgium in the 90s (or early 00) they reconnected the schelde and the leie, two rivers that used to be connected but were separated. The intend was to increase the debit that was missing from de schelde. This had a result of more oxygen in the water, increasing fish population and plant growth. 10 years after there were seals (and at some point even a dolphin) spotted in Ghent.
Covid has shown me that a lot of parents shouldn’t be. During the period that everybody was stuck at home there was a large amount of people that found out that they don’t know, or want, to raise a child and couldn’t wait to get them to schools or activities just to get rid of them.
My ex used to say “you can’t be expected to give up your social life just because you have a child”. My kids and I are better off now.
