In your household, try not to have any left-over food or to let any extra portions go to waste. Hint: this will require careful shopping. In your community, support food banks and programs that collect safe but unservable food from restaurants for distribution to hungry people.
Find out which animals from your part of the world are currently on the "Endangered Species" list. Ask animal rights and wildlife conservation groups what you can do to help these and other creatures survive in their natural habitats. Also, do your part to help other local animals through volunteering at an animal shelter, helping with educational programs for animal care, etc.
Obtain field guides to the plants, trees, birds, and small animals indigenous to your area. Learn the names of these neighbors. Read up on behavior patterns, territory, diet, and other qualities which distinguish one from another. Knowing names and characteristics is a way of honoring the diversity of the creation.
Using inclusive language is another mark of reverence. Review the language you use in worship, prayers, songs, and other community activities, and if necessary, revise it.
