Defenders of Wildlife is excited to welcome passionate advocates from across the country to Washington, D.C. for the 2026 Earth Week Fly-in. Together, advocates will speak up in support of endangered species and our most effective tool for preventing extinction, the Endangered Species Act. You’ll learn more about the congressional attacks facing the ESA – including Representative Westerman’s (R-AR) dangerous ESA Amendments Act of 2025 – and the most effective strategies for speaking up for wildlife in the halls of Congress.
