I don't grasp the literal litter benefit with respect to combating greenhouse gas emissions, but certainly more bicycle riding would be of some help. But I'm all for picking up garbage!

I'm not so concerned with scientists earning a living. If they want to become wealthy publishing science is certainly not high on the list of well-paying careers. I am concerned with the virulent anti-science efforts being waged in Washington and by interest groups and bloggers that are largely driven by industry funding.
