It was just discovered that bikes and walking are bad for the environment!
In a move of a sort of Nietzschian metaphysics and the follow through of quantum physics gone wild, it was discovered that, in fact, not only are gas powered machinery bad for the environment – it is now evident that most forms of movement are bad for the environment. Policymakers are now considering limiting the amount of movement per person allowed and/or making it a capitalistic good. At this point it is unclear if it is better to walk or drive a car as the research is showing that different types of movement effect the physical environmental differently and that things that move quicker generally create less damage to our precious earth.
