One of the big topics of a book I read was the full history and discussions between Canada and the United States with respect to the acid rain issue. If you don't meet with success, keep trying. You're not going to measure success in a matter of days, weeks, or months; you're going to measure it in years and decades, and we're going to work aggressively on this issue.
This is going to be the defining issue of my generation and the next two or three generations. It's not about tabling one plan and calling it a day. It's going to require constant attention for this generation and the two or three that follow it. We can't let perfection be the enemy of the good. We're moving forward. We're moving forward aggressively. For some it's not enough, but it's important that we get on with it, and that's why we're committed to real action.
