I'm a big walker. Because of where we live, I can walk to the grocery store, drug store, post office, gym, library, doctor's office, and the BART, which will take me into San Francisco, where I can walk some more.Consequently, I was pretty excited when the Alliance for Biking and Walking asked me to spread the word about their People Powered Movement Photo Contest.

Each week, we're sharing our favorite links from our friends at Planet Green and TreeHugger. Enjoy! Whiskey. Tango. Foxtrot? Paris Hilton builds a $325 mansion...for her dogs. Here's a cheat sheet—complete with pictures!—of the world's healthiest, sustainably harvested seafood.

I hear people bemoaning the high cost of "going green." And while organic food does cost more than its chemical-laden counterpart, I'm here to tell you that it's easier to spend more for healthy food when you save money in other ways. We can skip many of the green cleaners, deodorizers, and personal care products, most of which are fairly expensive. Why? Because baking soda is our friend. What's so great about baking soda?

Cycling has well-known health, social, and environmental benefits too, but the transportation mode's money-saving qualities may trump them all in this economy! If you're tired of paying at the pump, get a bike for nearby errands and pay quite a bit less -- or maybe even get rid of a second car or go car-free altogether for maximum savings! Some ways to get started, eco-nomically:

Today marks not only Halloween, but also the last day of the Eat Local Challenge -- and the last day of Fair Trade Month too. So I thought it'd be the perfect day to highlight some of the most eco-ethical coffees out there to go with your local, organic meals or fair trade chocolate desserts. Here are 3 tasty coffees that are not only all triple certified -- but have an additional little story to make you feel good about what you're drinking while jolting you awake too.

I hear it's gotten cold in some parts of the country, but we had a perfect summer day in Los Angeles today. So for those who live in similar weather -- or who just love chilled drinks whatever the temperature is outside, here are my top 3 recommended eco-ethical drinks to quench your thirst while supporting a good cause:

Maybe it's the fact that I've been spending a lot of time with our cat this week, or because I've been trying out a bunch of recipes from my Veganomicon cookbook, but I've been thinking a lot about animals lately.Do we want a second pet? Would I enjoy being a vegetarian, or vegan again? How long will polar bears be around?

What's more ironic than local, organic, seasonal food encased in plastic? That's what I wondered back in 2007 when I first started my quest to eliminate unnecessary plastic from my life. A trip to my local farmers market revealed more than just fruits and vegetables. Have a look at a few photos I shot:

This week, the Eat Local Challenge asks participants to look at how to expand the challenge to families.

Got an overabundant backyard garden or fruit tree? Don't let the extra food go to waste! In addition to sharing the bounty with your neighbors -- or getting really serious about canning and jamming -- here's how you can put your produce to good use:
