This wonít save the planet, but itís a useful and seasonal tip, here on the East Coast, because so many people go to Florida this time of year. Itís so tempting to bring reminders homeóeven when we should “Take only photographs, leave only footprints.” (And traveling by any vehicle other than a plane is also a good idea.) Iím not a regular Florida tripper, but a couple of years back I found myself with a small bag of shimmery white sand, full of tiny bits of coral and seashell. Not much use, not much beauty, and an ecological no-no to boot.

What I did was this: I put funneled the sand into a long clear whiskey bottle with a wooden cap. On its side, lying here on my desk, it reminds me of the sea and sunshine, of the wider world, on the beauty we need to preserve.
