Treehugger posted a couple of ideas from EcoAgents for all you take-out fans - next time you pick up your Thai food/pizza/cinnamon roll - refuse the extra packaging (napkins, forks, chopsticks, plastic bag, ketchup packets). Ask for "Just the food please" and then use your own reusable bag, cloth napkin or fork if needed. The next step is to aquire (and then remember to bring) your own food container. Refuse the styrofoam - it takes 400 years to biodegrade! Tiffin boxes are stackable lidded stainless steel food containers. Reusable Bags sells one along with sustainable bamboo utensils in a cool little pouch/napkin. Tupperware would work too.
And a word of advice from Casaubons Book - Start where you are:
Like everyone who comes to the peak oil and climate change movement, I have a past. Perhaps all of those reading this blog have a perfectly ethical one - you've lived your whole life in a one-room cabin lighted by your own hand-dipped beeswax candles. But I don't. I flew. I bought groceries from the supermarket. I had Barbies when I was a kid, - I'm pretty sure the plastic from will outlive my grandkids - and I didn't always fully understand the implications of population. And so I start writing from a post-lapsarian, fallen position, in which I have consumed more than my share, done environmental harm, and contributed to quite a few problems - including overpopulation. I admire those of you who come to this from a different perspective - who have never harmed the environment, and have always made wise choices. I have no difficulty at all admitting that you are better people than I am.
For the rest of us, we start from where we are. If you worked in the defense industry, or you had more than a just share of children, you bought designer clothes made by slaves, you burned oil that warmed the planet and that nigerian peasants were murdered for - the only thing we can do is to go forward from where we are. The thing is, if the only people who are allowed to speak are the ones who have always done the right thing, and always lived the right life, it will be a very quiet place. Me, I'm for having everyone speak. It isn't that I'm suggesting absolution - each of us has to deal with our prior impact in our own way. But angst about what is done is an indulgence I don't think we have time for - there's simply too much useful work to be done.
