Umbra on Wal-Mart

Dear Umbra, Why is Wal-Mart evil? This is really a request for more information. I have often heard that the company has a weak environmental track record, treats its employees poorly, and generally is Satan incarnate. However, when challenged on this position, I have no data. My opponents argue that shopping in bulk reduces packaging. […]

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 the health/environment dividing line

Yowza. A few weeks back, in response to a question from a reader named Cassandra about the relative merits of soy milk, I asked your opinion on the dividing line between health and environmental concerns. Cassandra wanted to know if she could continue eating soy, which she considered an environmentally sound choice, without increasing her […]

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 […]

Umbra on protecting decks

Anyway, the reason I’m writing you is because I’m looking for some advice. Do you have any recommendations on environmentally conscious ways to protect household decks? Lori and I just bought […]

Umbra on lead pipes and drinking water

Dear Umbra, I live in New York City, which is reputed to have some of the best drinking water in the U.S. But I also happen to live in an old building that probably has lead pipes, so I buy Poland Spring water in five-gallon jugs each month. I’d prefer to drink tap water, but […]

Umbra on UV ratings

Dear Umbra, Our radio station provides daily information regarding ultraviolet ratings. I am curious about what these ratings actually represent, and why they change so dramatically. For example, for the past few years, most ratings have been between three and seven. Now we are getting ratings of 10. I doubt the ratings are directly related […]

Umbra on the mysteries of produce code numbers

Dear Umbra, I recently learned that the UPC numbers on produce indicate whether the item is conventionally grown (beginning with a 4), organically grown (beginning with a 9), or genetically modified (beginning with an 8). I like to buy organic, locally grown produce at my local health food store whenever possible, but recently at a […]

Umbra on the eco-relevance of health concerns

Dear Umbra, As a practicing vegan for quite some time now, I take pride in my knowledge of nutrition and my ability to enrich my body through a varied diet with all the essentials. For the past five years or so, I have heavily relied on soy products for protein and other nutrients. Recently, however, […]
