In short, Earth Day participants not only get alot done, they also demonstrate that human beings everywhere are driven by their faith, their conscience, their sense of duty, or by a moral imperative to save the planet. It is staggering to think about one billion people working together in a collective action.

Environmental issues haven't been a main topic of the election. Why? Because they have no credible environmental track record to promote (in the case of Obama) or no plan that can be explained in a few words or less (in the case of Romney).

We simply can't let Mitt Romney buy the keys to the White House and let the special interests write our nation's energy plan behind closed doors. He'd roll back every step of progress we've made -- not just in the last four years, but the last 40 years.

Despite his administration's rhetorical embrace of clean energy, when push comes to shove, Obama is effectively using modest wind and solar investments as cover for a broader embrace of dirty fuels.

We need to reach past people's heads to their hearts. Environmentalists have traditionally been more comfortable with the side of the brain that likes bar graphs; we need to engage the rest of our souls in this movement.

Environmentalists need to be aware of so-called "progressives for immigration reform" and their true motives. These individuals and organizations do not see protecting the environment as their primary goal.

These are the people and groups who toil, every single day, for a better environment, no matter what. Here in Brooklyn, we are taking out some time on this environmentally symbolic day to honor some of those groups and people.

This downgrading of Earth Day resurrects the tired old shibboleth that when economic growth and environmental reform appear to be in conflict, the latter must give way.
