Contribute to nature reserves and other wilderness areas. Habitat preservation is one of the best ways to help protect animals. You can donate money or volunteer your time helping the nature reserve preserve habitat.
Buy environmentally friendly goods. Choose non-toxic cleaners and lawn care items that won't pollute streams, rivers or oceans. Avoid any products that have been made from threatened or animals. Buy foods and goods that are made from materials that do not harm animals or their habitat. For example, look for organic chocolate, coffee or cotton clothing that is grown without cutting down rainforests or destroying habitat.
Create or restore habitat for animals. You can volunteer to help with projects worldwide designed to reestablish habitat. In your own backyard, plant a butterfly garden, use native plants and trees and let "wild" areas grow to provide habitat and food.
Join a local, national or global conservation organization. Some organizations focus on one particular animal while others focus on broad efforts for all species. You can "adopt" an animal through these organizations, which makes a great gift idea as well.
