All Stories

  • Umbra on moving to Canada

    Dear Umbra, Did you really move to Canada? Did you get resident status? How hard was it to do? ValerieMiddleburg, Va. Dearest Valerie, I haven’t actually moved to Canada. I was being dramatic (lying) and I apologize to all who were duped by my ruse. I was also deeply touched by the hearty if unnecessary […]

  • Umbra on trains vs. cars

    Dear Umbra, My girlfriend recently made a trip by train (about 600 kilometers, I’d guess), and it made me wonder just how much more ecological it is to travel by train instead of by car. What’s your take on this? MichaelOttawa, Ontario, Canada Dearest Canadian Michael, The train, it is better. The car, it is […]

  • Umbra on renting hybrids and sharing cars

    Dear Umbra, Do you know of any car-rental companies that offer hybrids? I have heard of a bunch in environmentally friendly California, but my quick search in the Boston area has turned up nil. With high gas prices, I think I’m brewing up a new campaign! JeanDorchester, Mass. Dearest Jean, An environmentally focused rental group, […]

  • Umbra on how climate change will affect us

    Dear Umbra, My girlfriend asked me the other day why global warming was going to be so bad for her. I just graduated with a degree in environmental science, and I like to think I learned something in my classes, but I still struggled to give her a concise, straightforward answer. I see new research […]

    Dear Umbra, What percentage of the Earth’s water is drinkable? What are the remaining percents in categories, such as salt water, polluted water (polluted with what?), and frozen water? And where can I find these statistics? ScottBozeman, Mont. Dearest Scott, About 70 percent of the Earth’s surface is constantly wet. Of all that water, only […]

  • Umbra on composting

    Dear Umbra, Can you tell me what is the best and most effective composter for a small urban backyard? JoeBaltimore, Md. Dearest Joe, Sort of. It’s ultimately a very personal choice, and one that depends on what you will try to compost and the amount of time you are willing to spend helping the compost […]

  • Umbra on wind farms

    Dear Umbra, I have been reading lots in the media lately about wind farms. As a supporter of green energy, I would obviously like to see a lot more of them and have long believed that people who oppose them are just another example of the “not in my backyard” mentality: they want a constant […]

  • Umbra on odd fruit

    Dear Umbra, Yesterday in the grocery store I saw a “golden kiwi.” Is there really such a thing? It was over twice the size of a regular kiwi and the familiar fuzz was not there. It was almost as smooth as a nectarine. When I inquired of the produce representative, she told me that it […]

  • Umbra on the environmental impacts of soy

    Dear Umbra, I’m interested in learning more about the treatment and genetic modification of soy and how prevalent this is. I think a lot of folks choose products such as soy milk because they think they are making a better choice for the earth, as well as themselves. I think this is an overlapping issue […]

  • Umbra on birds bursting into flames

    Dear Umbra, I saw the following on the CNN website. Can this possibly be true? I see birds hit, land on, peck at, and poop on power lines all the time, but I’ve never seen one burst into flames. LOS ANGELES, California (CNN) — Weather forecasters predicted little relief Monday for firefighters battling wildfires that […]
