"You don’t have to feel overwhelmed by this list: to start, choose just one item and put energy behind it. Doing something is better than nothing. In doing these simple acts of environmental service, you may feel that your contribution doesn’t matter, that it won’t make any difference against the magnitude of the world’s ecological issues, but remember that “by small and simple things are great things brought to pass” (Alma 37:6).
In spiritual matters, we don’t stop choosing the right just because the world is growing more wicked! We know that our small acts of kind service won’t stop all the evil in the world, but we continue to perform them anyway, blessing lives in the process. We can have a similar attitude toward the earth and her inhabitants."
