When I wrote my post Ten Ways the Childless Limit their Environmental Impact I forgot to list the biggest way our environmental impact is reduced. I was reminded of it by a comment on a social media group for those who are ageing without children, just after I had written my post. "Of course!" I said, embarrassed that I hadn't included it, although I kind of touched on it when I talked about housing.
Our environmental impact ends with us. We don't have children who go on to place stress on this already stressed planet, by doing all the things we all do (or did) - require food, clothing, housing, heating and/or cooling, transportation, technology, etc. We don't have children who have more children who go on to place stress on this planet.
Feeling good? Good, you should. This is one of the silver linings of infertility. And one of the best ways we can contribute to the future of other people's children.
Did I miss any other points?
