Several things can contribute to a relatively low carbon footprint. A modest simple life leads to less energy consumption along the various tools and gadgets technological process. Then a focus on learning and stoking the flame of curiosity detours one from vanity and actually towards being creative/productive. Then there’s of course greed and planned obsolescence. The warming of the planet is entirely a natural process but the levels of carbon dioxide driving it now are quite clearly human caused. Some global warming is almost definitely caused by humans, but some of it is also definitely caused by natural processes. Almost all climate scientists agree that humans have contributed to global warming. But there is also widespread agreement that the warming seen in the first half of the 20th century was mostly not caused by us. I find all of this entirely believable, since it rests on fairly solid science as far as I can see. To put it in perspective, temperatures are thought to have increased by an average of about one degree over the past century or so, with some places warming more and others warming less or actually cooling. Temperatures in any individual place have also tended to fluctuate by much more than this from year to year, up and down. If we learn how to lessen our carbon footprint at home and continue to educate others, we can still make an impact on slowing global warming down.
