Bicycling Not Always Environmentaly Friendly

While surfing the net for other bicycle related sites it seems to me the majority of them have a green theme or a environmental message attached.
I suppose when it comes to us and bicycling we”re doing more harm to the environment than good.
We”ve burned thousands of gallons of gas to haul us and our bikes to cool places to ride that we probably never would have visited otherwise.
Oh well… we have a good time.
We do turn the lights out when we leave.
