being raised by an environmental engineer and a social worker surely had an impact on my consumption. i'm quite fond of the recycline toothbrushes and disposable razors. they give you a postage-paid envelope and when you're done with the toothbrush/razor, you throw them in the envelope and mail them back and they turn them into park benches. they also have a subscription program where you can automatically be mailed a fresh toothbrush/razor/razor blades every x number of months.

locally they have 'em at trader joe's and whole foods, but you can of course get them online as well.
