Now that the presidential race is off and running, it's time to compare and contrast what the two White House kitchens might look like in the way of sustainable food sourcing. Take a little break from the political arguments about economics and Iraq and peek into the possible future White House kitchens.

First, a look at the two candidates' food preferences:

Barack Obama seems to be a committed omnivore and will eat just about anything he's served on the campaign trail. Given the choice, he leans toward grilled fish, vegetables like broccoli and spinach, and for snacks, he'll go for organic Honest T Blackforest Berry, roasted almonds, and protein bars. At a stop in Washington, he hit a deli marketplace and excitedly sampled and purchased some fancy cheese and charcuterie. His favorite dish to cook is chili and he doesn't like beets. He's often seen carrying plastic water bottles but he redeemed himself somewhat with this comment: "we can't drive our SUVS and eat as much as we want...and then just expect other countries are going to say ok."

John McCain's favorite foods are shrimp and pepperoni pizza. Required snacks on the campaign trail: Dunkin donuts and Coke. He likes to cook ribs and says he doesn't "do well with vegetables."

Clearly, Obama's ahead of the game as far as enjoying vegetables, buying organic (at least sometimes) and eating a diet that's good for his body. And personally, I'm encouraged by his obvious enjoyment of delicious food. But there's always room for improvement:

Answer: your clothes.

EcoSalon wants you to air your laundry. In some parts of the world, people routinely hang their laundry out to dry instead of using electric or gas dryers. And I’m not talking about the developing world. It is common not to even own a dryer in Europe.

You hear cynics say that bringing your own grocery bags to the store isn't going to make a difference. That we need to get industry to stop polluting and government to commit to renewable energy. And then they say, with none-too-little smugness: "But hey...go ahead and do it if it makes you feel better."

Why, ...Read More

School is letting out and I hate to think that high gas prices and fuel shortages will make the summer road trip a thing of the past, because there are some worthy reasons to load up the family and take a little drive to a pretty place where the kids might learn something valuable.

Our National Parks are a precious sanctuary from modern life. Places where you can view an infinite number of stars, or enjoy a hike that is completely silent - save for the calls of birds and the rustling of grasses. Places where you might see wildlife like coyotes ...Read More

Golden Staters are accustomed to conserving water as a matter of habit. Many communities are now or will be under mandatory water rationing, including mine, so I've had to figure out how I can improve on my already conservative water use habits. But, conservation is important for everyone for two reasons: 1), worldwide, we are facing water ...Read More

Tomato season is just beginning and you're probably pretty happy to eat them raw in salads or simply drizzled with olive oil and salt and pepper. But come August or September, you might be glad you tucked this recipe away in your bookmarks folder. (Especially if your neighbor dumps a heaping sack of squash on your doorstep).

Fragrant, bright green, giant bunches of organic basil show up in farmers' markets and CSA boxes all summer long. If you're like me, you'll throw a few leaves into a salad or sandwich, but you may have a hard time using up a whole bunch before it goes bad, unless you make a batch of pesto.

Here's a tip straight from a farmer. Simply put ...Read More

Talk about rotten tomatoes. The outbreak started in mid-April and there have been cases of illness in at least 17 states (including Arizona, California, Colorado, Connecticut, Idaho, Illinois, Indiana, Kansas, New Mexico, Oklahoma, Oregon, Texas, Utah, ...Read More
