How about some non-biodegradable piece of crap to advertise our virtues? ;-)
The worst aspects of capitalism are often fueled by mere acquiescence borne of a completely earnest desire to be pleasant, polite, and kind.
We should feel more free to say things like:
"No I don't want that stupid fucking rubber wristband that was manufactured in China for two pennies and that you bought for fifty pennies that's going to choke some fish to death after I wear it for five minutes and then sit in a landfill somewhere forever after that in exchange for my donation. Just take this money, actually make some progress on a cure for breast cancer, and stop contracting people to manufacture pollutant crap that they want to profit from without any actual concern for their fellow man or their environment. And by the way, thank you for caring enough about this cause to give your time to try to get the rest of us to care."
Oh, and we should also stop being so mindless as to believe getting some non-biodegradable piece of crap to advertise our virtues is doing anything to help the causes they supposedly further.
Living by the principles we think we espouse is actually and often more harsh and anti-social than anyone told us it would be.
