Due to the use of DDT and other pesticides, there were fewer than 100 Peregrine Falcons in the lower 48 United States in the 1970s. Bald Eagles had dropped to fewer than 1000 individuals across the same area. Thanks to the effects of science-based environmental regulations such as the Endangered Species Act (ESA), Migratory Bird Treaty Act (MBTA), and Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), there are currently ~5,000 Peregrine Falcons and ~300,000 Bald Eagles in the lower 48!
The recovery of these two species is due almost entirely to legislation that is scheduled to be officially “sunset” by Executive Order dated 9 April 2025 (“Zero-based Regulatory Budgeting to Unleash American Energy). The damage that this could cause is immeasurable and could take decades of concerted effort to recover from. In some cases, the damage could be irreversible, as many endangered species could very quickly go extinct without protections.
Environmental regulations protect not only plant and animal species but every person on the planet through clean air and water, and it is estimated that the environment provides approximately 150 trillion dollars of economic benefit globally every year for free (Jiang et al. 2021). Recovery of the Peregrine Falcon and Bald Eagle are just two of many stories that demonstrate the power of regulation in conserving the natural world that we all live in, depend on, and enjoy.
