Climate Ask Umbra

All Stories

  • Umbra on burning trash

    Dear Umbra, We recycle and compost as best we can, but we are still left every week with some trash. Up to this point we’ve dutifully hauled it to the local dump, which then trucks it away to some landfill. My husband has recently discovered that, since we live outside of city limits, we are […]

  • Umbra on eco-choices

    Dear Umbra, While I usually love your column, I have to take issue with encouraging people to eat sushi. This is the second “green” site I have seen that proposes the solution to overfishing is to eat different fish. Saying “of course you can continue to eat at sushi restaurants without feeling guilty” amounts to […]

  • Umbra on the promise of ethanol

    Dear Umbra, Lately I’ve been struggling with the idea of ethanol as a green fuel. It seems to be getting a lot of attention in the government and media, and it is being touted as the answer to this country’s petroleum woes (see GM’s “Live Green, Go Yellow” campaign). But from what I’ve read, ethanol […]

  • Umbra on peak oil

    Dear Umbra, I have recently been alerted to what many people term “peak oil.” I don’t know how to characterize my feelings regarding this subject. Obsession might be a good term. I feel that I need to prepare. What do you think? Is “peak oil” another Y2K? MichaelPittsburgh, Pa. Dearest Michael, Who cares if it’s […]

  • Umbra on sustainable sushi

    Dear Umbra, My wife and I love sushi, but we’re increasingly concerned about sustainable harvesting. Although we treat ourselves to sushi only once or twice a month, it adds up, and we can’t help but wonder about the impact. There’s no sensation in the world like letting a slab of sashimi salmon dissolve in your […]

  • Umbra on eating locally in winter

    Dear Umbra, I live in New Hampshire, and I am getting ready for the long, cold winter. I try to eat locally, but with no year-round growing season here and such a dense population, most of the food comes from elsewhere. I was wondering what I could do to reduce my impact during the winter […]

  • Umbra on Halloween

    Dear Umbra, What do you recommend handing out to the trick-or-treaters this Halloween? I would like to avoid the wasteful packaging and additives found in store-bought goodies. I’d bake my own treats, but I doubt parents would let their kids eat anything that’s not individually sealed. How can I have an environmentally friendly Halloween? Robin […]

  • Umbra on oil drilling and seismic activity

    Dear Umbra, How is drilling for oil affecting the stabilization of our planet? I wonder how much all the drilling is disturbing the earth’s crust. Could this be part of the problem causing tsunamis, earthquakes, and tidal waves? Susan Milliner Cedar Park, Texas Dearest Susan, Oil and gas drilling can do all kinds of nasty […]

  • Umbra on toxic schools

    Dear Umbra, My four-year-old daughter is attending a brand-new preschool program in a brand-new building this fall. Nothing was missed in setting up the school for the best possible education for young minds. Unfortunately, it’s filled with all those toxic “new” smells. When we toured the building, I developed a headache within five minutes. Are […]

  • Umbra on fire-fighting chemicals

    Dear Umbra, Nearly every day, I can hear slurry bombers (planes that dump bright pink goo at the edges of fires) zooming overhead. I think the bright pink goo is a flame retardant, which seems to recently have gotten a bad reputation as a carcinogen. Not only that, but folks who have dogs here claim […]
