I was struck by this photograph of Earth sent back by the NASA spacecraft Artemis as it orbited the Moon. From about 240,000 miles away the small dot which is us is so distinctive in its blue-ness even at such a distance. This is, of course, the thin fragile atmospheric layer that has allowed life on Earth to flourish for so many millions of years. We are the generation that seem intent on squandering it.
