1. Get real. The world's great polluter is China. Chinese diesel fumes and dust can be detected in air streams thousands of miles away. Do you think a government that admits to the deaths of 11,400 people per year on the job is going to worry about fumes?

2. As for "So when does America accept the message and do its bit to help the planet?" Who do you think did the most work in discovering and publicizing global warming? Whose cars have catalytic converters? Whose gas has no lead in it?

3. Take a walk down a street in Paris someday and see if you, like me, don't start choking on the diesel fumes. The air on main streets in Paris and in smaller cities was awful. Why? because diesel's cheaper than gasoline. Whether it's global warming, ozone destruction or something else, those fumes are going to hurt the planet one way or another.
