"Many people understand the dire state of the planet—but do nothing about it because they feel helpless and hopeless. That is why this book is important, as it will, I hope (!), help people realize that their actions, however small they may seem, will truly make a difference. The cumulative effect of thousands of ethical actions can help to save and improve our world for future generations. And why would you bother to take action if you did not truly hope that it would make a difference?"
