Airgu, Spin down a bit, pal. The fact is there are plenty of other more real issues that actually do impact the environment. In Germany for example, try and find a single dirt roard where you can LEGALLY drive in a forest. There isn't one. You can walk, or ride a bicycle, but that's about it. Germany is an outstanding country. I just returned from living there for four years. It has some of the finest motorcycling roads in the world. But the overuse of thier forested areas has made them virtually unusable. There is no such thing as old groth anymore. Almost all the forested land there is like a plantation of evenly spaced trees with little natural undergrowth. There are a few rare exceptions to this, but very few. I didn't say that we shouldn't protect the environment in a common sense and balanced manner. All I said was that I don't think my canister makes much of a difference. Certainly not enough for "canister removal" to rise the level of a moral, ethical issue. So, you live in Germany. It's forests and nearby mountains need protection as you've stated. Do you have a canister on your bike? If not, I have a spare, if you'd like to do more than talk.
