I agree with RudeBoy here. All too often people are keen to point out the terrible environmental destruction caused by this that or the other: be it mtbers, plastic bags, plane flights, etc. But, when it comes down to it, to the real nitty gritty, in your face, brutal truth, how many of you do anything about all that?
TJ, do you drive your car to get to all these amazing mtb trails that are eroding away? If so, then I would, politely, ask you to, ahem, shut up and put your money where your mouth is. Do you fly to the Alps or Spain for your summer fun?
Its all very well getting angry about people being unsustainable or environmentally ignorant, but until you actually do something about your own lifestyle and practices, then you are in little position to preach.
I have no car, don't drive, nor fly. I shop locally and am a vegetarian. But I pollute, I buy things, bike parts, newspapers, etc. I am no eco saint, I am a consumer like the rest of us here, and that means I royally **** the environment up. Maybe we should think about environmental matters in a much more holistic manner. It's harder to do, and asks real questions of us, but at least it would address the real problems with our lifestyles.
