I see that Disney is trying to be more green or environmentally friendly. I often wonder how they have let the speedway in the MK stay open while emits those toxic fumes into the air all day/every day. My children always want to go on the speedway but I don't want them to breath in the fumes. I wonder how Disney can with a good conscious let CM's work there all day and breath in that air. Is Disney going to do anything about replacing the cars to cars that don't omit such terrible fumes??? I often wonder why they have not addressed this issue.
