"The wild animals we enjoy and would like to have in our lives will not be part of our future if we take away their food and the places they live. Unfortunately we are doing just that by trading our wild-lands for uncontrolled expansion of suburbia. The obvious consequence is that in too many areas of our country there is no place left for wildlife other than suburbia itself.  This forces those who value biodiversity to consider a new approach to gardening in suburbia. For suburbia to become a functioning ecosystem for more than just humans, we must first accept the notion that all plants are not created equal, particularly in their ability to support wildlife. Most of our native plant-eaters are not able to eat alien plants.  Therefore, if we want to support wildlife, we have to increase the number and diversity of native plants in suburbia. Fortunately, this is quite easy to do. "
