I think it is time someone asked these nitwits just how much oil awas consumed and emissions made by their aantic. Neither are local people, so how did they get there? Walk? walking being the only form of transport that does not involve oil in its manufacture, let alone use, then i would like to know the energy implictions of the powde they use, the canisters it is in, the police cars etc that have to drive their to arrest them and take them into custody - and their journey home.
I also wonder about their shoes. Are they wearing modern trainer/walking shoes - made almost entirely from oil based products. let that be counted in.
Then we get them to produce a cogent sensible reason how using all this oil promotes their cause.
We are all aware ofg lobal warming and its affects Just stop oil actually do their cause an incredible amount of harm, by associating it with crackpots and weirdos.
