This year, we’re celebrating the 45th anniversary of the Marine Mammal Protection Act (MMPA). The MMPA is a bedrock conservation law that was passed in 1972 to prevent the harassment, capture, injury, or killing of marine mammals. It’s vital for protecting whales, dolphins, porpoises, seals, sea lions, walruses, manatees, sea otters, and polar bears from the many threats they face in US waters.
Threats to marine mammals have multiplied over the past 45 years, as crises such as bycatch, oil spills, and impacts related to climate change worsen in our industrialized world. It is time to maintain and strengthen the law that has been so effective at mitigating threats for these species—not weaken it with attacks designed to benefit offshore drilling and other industries.
Your members of Congress need to hear from you about how much you value the MMPA, and how marine mammals desperately need ongoing protection. Please write to them in honor of the law’s 45th anniversary and urge them to oppose any bills designed to undermine its effectiveness.
Be sure to share our Dear Humanitarian alert with family, friends, and co-workers and encourage them to speak up, too. Thank you for taking action on behalf of marine mammals!
