The Philadelphia Zoo is involved in helping endangered species in places around the world. The Zoo is also hard at work "going greener," having engaged a recent audit of energy use, water use and waste disposal to establish a baseline measurement of our environmental impact, and moving toward the goal - via carbon offset projects and on-site sustainability measures - of becoming an energy neutral organization over the next ten years.
The Zoo also challenges you to do your part - here on this site you have a unique opportunity to both calculate your carbon footprint and then make a donation to plant trees that will help offset your environmental impact.
