  • Umbra on skiing

    Dear Umbra, With winter fast approaching, I was thinking of learning to ski. I was wondering how skiing ranks among recreational activities in terms of its environmental impact. What are all the effects of clearing ski trails, making snow, and operating ski lifts? Not to mention all the resorts and roads that sprout up to […]

  • Umbra on snowy sidewalks

    Dear Umbra, Being a new homeowner, I’ve realized the responsibility of keeping the sidewalk slip-proof during the winter months. Of course, shoveling will be the first line of defense, but that never seems to do the trick, often leaving that thin layer of slippery snow. And then there is the ice. I know that salt […]

  • Umbra on wrapping paper

    Dear Umbra, Any suggestions on where to find recycled wrapping paper? I know the real environmental choice is to reuse stuff I have around the house, but sometimes newspaper, etc., just doesn’t have the right look. Any ideas where I can find recycled/tree-free wrapping paper for the holiday season? I’ve been looking around (both online […]

  • Umbra on organic food and farming

    Dear Umbra, I try to buy organic food where possible, but I notice that there is often a tradeoff with other factors. For example, organic food has often been shipped further and/or is more heavily packaged. How do I assess those tradeoffs? EllenWatertown, Mass. Dearest Ellen, As I’ve mentioned before, the USDA national organic standards […]

  • Umbra on fruit sprays and organic food

    Dear Umbra, The tangerines I bought recently had this on the label: “Thiabendazole and/or orthopenylphenol and/or imazalil used as fungicides, and coated with food-grade shellac based wax or resin to maintain freshness.” Presumably the shellac stays on the skin and does not affect the fruit, but what about the other products? What are these products […]

    Dear Umbra, I have been a vegetarian for a pretty long time, but my uncle told me that if the human is not supposed to eat meat then why do we have teeth. He left me a little confused.

  • Umbra on sustainable bunk beds

    Dear Umbra, I’ve been looking for a sustainably harvested bunk bed for my five-year-old son for quite some time now. I have found only one company, Pacific Rim, that makes such an item. It seems like a great company, but it doesn’t have exactly what I’m looking for. When I search online, all I read […]

  • Umbra on making mulch from paper

    Dear Umbra, I know this is a silly question, probably the strangest you’ve ever gotten, but I’m curious. Where I live, there isn’t a place nearby to recycle paper. I reuse most of my paper as scratch paper and have attempted to make my own paper using a blender and a screen. The problem is, […]

  • Umbra on cushion planters

    Dear Umbra, I have been cutting out old cushions, filling them with dirt, and planting them for some years now. I found the first two floating in the river (while canoeing). Since then, I’ve gotten them from the trash; I don’t pay anything for them. I use them to grow everything from herbs to prairie […]
