To me, charity often is just about giving, because you're supposed to, or because it's what you've always done - or it's about giving until it hurts.

Just because you have a piece of trash and you throw it away and it gets hauled away, it doesn't mean that it's not affecting someone else.

One thing I noticed working in the Bronx is that leaders come in the craziest places. They don't always show up at community board meetings. Sometimes it's just the guys on the corner that the boys on the block respect.

You know, people understand fear and opportunity. It may look different, but it's really the same thing.

As a black person in America, I am twice as likely as a white person to live in an area where air pollution poses the greatest risk to my health. I am five times more likely to live within walking distance of a power plant or chemical facility - which I do.

Many people still believe that 'green' solutions are too expensive, but they are actually much cheaper when all of the costs to public health, social services, and waste handling are factored into the same equation.
