Pollution is nothing but resources we're not harvesting.

Whatever humans have learned had to be learned as a consequence only of trial and error experience. Humans have learned only through mistakes.

You can never learn less; you can only learn more.

By and large, I seem to have made more mistakes than any others of whom I know, but have learned thereby to make ever swifter acknowledgment of the errors and thereafter immediately set about to deal more effectively with the truths disclosed by the acknowledgment of erroneous assumptions.

Pollution is nothing but the resources we are not harvesting. We allow them to disperse because we've been ignorant of their value.

Never forget that you are one of a kind. Never forget that if there weren't any need for you in all your uniqueness to be on this earth, you wouldn't be here in the first place. And never forget, no matter how overwhelming life's challenges and problems seem to be, that one person can make a difference in the world. In fact, it is always because of one person that all the changes that matter in the world come about. So be that one person.

Nature is trying very hard to make us succeed, but nature does not depend on us. We are not the only experiment.
