You should begin to include reading realistic stories about the animals around them. Educate them about farm animals, insects, birds, reptiles, common pets, and other animals. Make sure you include information about how important animal roles are in our lives. For example, snakes are natural rodent population controllers. This helps prevent invasions into our homes and keeps disease and contamination down.
Insects help to clear up debris and decay and also pollinate flowers and fruit trees.
Birds and bats help to control insect populations. There are a wide variety of things you can teach from each type of animal group surrounding you. There are also television networks and channels that only focus on animals. These are available to many of us and can be good entertainment and teaching tools. Remember that the best learning is live observation, but this media opportunity can bring other animal issues and related environments into the home where they might not be accessible otherwise.
