RICH AND POOR, UNITERS AND CANCELERS
Matt Stoller, in "It's Global Warming, Stupid!" (January/February), says, "Global warming is a rich person's problem." Stoller opposes a carbon tax, which, he says, would burden the poor and benefit the rich. But drought, storms, rising sea levels, diseases, and other problems associated with global warming will first harm the most vulnerable among us: the poor. Donald A. Smith
I congratulate the Sierra Club for including Newt Gingrich in the debate on global warming. I know many Republicans who are pro-environment. We need to work together on a new global-warming Manhattan Project. Alex Aliferis
So you believe that Sierra is an appropriate platform for Newt Gingrich to offer his self-serving prescriptions to return Republicans to power? Fine. You can cancel my subscription. Jeffrey Corbin

NUKES OR NOT?
Marilyn Snell's article "Power Hungry"(January/February) captures the conflict environmentalists feel toward the nuclear option. The natural tendency of environmentalists is toward the ideal, and nuclear power is anything but. However, as France has shown, if carbon is your problem, then nuclear power can be a big part of the solution. Jim McNeil
I learned to love the pressure cooker ("One Small Step," January/February) when I was a Peace Corps volunteer in Lesotho, South Africa, where the need to carry the kerosene for my cookstove three kilometers up a mountain was all the incentive I needed to be very efficient in my cooking habits.

GREEN AND GREED
To include Kraft Foods as a player in promoting sustainability ("Green and Greed: Can They Get Along?" January/February) is bad news. Kraft continues to expose the U.S. population to untested, unlabeled genetically engineered food. To learn more, click on sierraclub.org/biotech. Laurel Hopwood

While I appreciate the context of the package "Green and Greed," there is no real examination of the effects of Wal-Mart's "greening." Wal-Mart carries organic food. However, instead of supporting farmers closer to home, it imports cheaper "organic" food from China and Brazil (countries not known for their organic oversight). Rena Dubin

"Sustainable Crustaceans" ("Lay of the Land," November/December 2007) noted that Wal-Mart is selling certified sustainably farmed shrimp. No internationally recognized standards currently exist for aquaculture sustainability.
