A Timeline of Major US Environmental Milestones
Have you ever wondered about how the environmental consulting industry took shape? Driven by a series of groundbreaking laws enacted by both state and federal agencies, and beginning in 1916 with the creation of the National Park Service, it is hard to imagine a time and place when and where our most precious natural resources were not protected with a mindset of preservation for future generations. Looking back, we realize how far we have come, paving the way for many other nations across the globe. We hope that this timeline puts our journey into perspective. We will continue to update it as new landmark laws are enacted. Thanks for visiting Apex Companies, and may we all seek to make the world a better place than we found it.
