Doug Oster, our friendly gardening guru/blogger (check out Digging with Doug and don't miss his fresh gardening videos each Saturday during the growing season) sent a press release my way the other day about Cafe Phipps "Meatless Monday and Meat Free Monday." Besides going for better health via veggies, taking meat out of the equation reduces your meal's carbon footprint.
According to our friends at the Phipps (and many other sources by the way) meat production is responsible for a large chunk of global greenhouse gas emissions. So less meat, less emissions equals better environment and if you need your protein fix sub out meat with tofu.
Going from eating green to shopping green, the PG's China Millman goes into bags in a big way. Everywhere you go now, stores have their own reusable shopping bags for sale. Thing is you want to look for certain things when buying your bag; I've had some that once you put anything heavier than a jar of pickles in to them, the bottom feel right out. And if you have extra canvas bags about, consider donating them to the Food Bank or maybe a local food pantry.
