the one planet that we've got. so i believe this moment can be a turning point for the world. we've shown that the world has both the will and the ability to take on this challenge. it won't be easy. progress won't always come quick. we cannot be complacent. while our generation will see some of the benefits of building a clean energy economy, jobs created, money saved, we may not live to see the full realization of our achievement, but that's okay. what matters is that today we can be more confident that this planet is going to be in better shape for the next generation. and that's what i care about. i imagine taking my grand kids, if i'm lucky enough to have some, to the park some day and holding their hands and hearing their laughter and watching a quiet sunset all the while
