Am currently reading Matthew Sleeth's book: Serve God, Save the Planet. Although I can't speak to the tone set in this book, I can say there are many compelling points in her husband's book. And quitting your job at the ER to share this message far and wide has a far wider reach. Matthew Sleeth saw so many disturbing effects of our lifestyle in the ER, people suffering in ways we should never have to suffer and children dying from pollution. This is not okay! I appreciate this family's commitment to changing the course of our nation starting with themselves. If this author is off-putting, read her husband's book, or find other resources that help you get behind the message and make changes in your own life.
