a world of good PENNSYLVANIA’S TITANS OF CONSERVATION BY ERICA LEVI ZELINGER The modern-day environmental movement began 50 years ago with the first Earth Day celebrations, but history shows us that Pennsylvanians have long played a role in educating others about the effects of human interaction with the natural world — and well before 1970. As we grapple with issues of climate change, pollution, and waste, there are lessons to be learned from Pennsylvania’s original conservation icons about environmental protection. Follow us on a journey to experience their legacy firsthand as these Pennsylvania partners worked — from the early days of statehood onward — to educate and mobilize others to care for and protect the planet. 48 visitPA.com CREDIT VISIT HERSHEY HARRISBURG
