Motorsports and the Environment

Well, after months of soul searching, I have decided to give up my support of motorsports in favour of the environment.
There are more reasons to end my support of racing than the fuel issue alone.
A lot of other chemicals are used in the construction, maintenance and running the whole team.
Team transportation by truck and planes around country or world depending on the series.
Teams can use 20 sets of tires over a weekend.
Then there are the venues. Miles of pavement. Gas, oil and chemicals leaching into the ground.
Plastic and styrofoam from the concessions and the transportation of the fans.
It all adds up so I've taken the last checkered flag.
