Imagine, if you will, a chap called Marty. Marty is not a villain. He does not chain-smoke in busy restaurants, nor does he kick puppies for sport. He is, by all metrics, a reasonable fellow – he pays his taxes, diligently rinses yoghurt pots for recycling, and occasionally even “likes” alarming climate-change posts on social media as a member of the “concerned citizens” club.
But every Sunday evening, Marty sits down to a large steak, convinced that his personal carbon footprint has been compensated by the sheer moral weight of a reusable water bottle he bought in 2019.
