you still don't get it? i suppose you never will then. I'll say it again just for you anyway: ITS NOT THE RIGHT ARGUMENT AGAINST THE TRACK. PEOPLE WILL LAUGH AT YOU IF YOU USE IT.
Did I at any point say C02 emissions are great? But it IS grains of sand, so you're mixing your issues here. One is you don't like dirtbike riders. But I bet you drive around in car and spew your own CO2, which is the argument you're trying to use against them?
If you really think it is the crux legitimate issue that will change whether the track is built or not then why are you wasting time with this insignificant issue (the building of one dirtbike track) in the larger issue of CO2 emissions? Why are you centering on these poor people and their dirtbike track? If you REALLY want to fix the problem then work with/against the dirtbike makers to come up with a bike that reduces/eliminates CO2 emissions. Or what about cars? Or factories? THAT would make sense.
Or I guess you can save the planet by eliminating this one dirtbike track. Or you can get real, leave these people alone, and fix the real problem. You're trying to pin the whole world's CO2 emission problem on this one little track. I'm not denying a worldwide CO2 emission problem when I say that is retarded. Again, the issue being debated is this one track, not the whole world.
