Environmental groups sue over drilling carve-out for Gulf wildlife protections

Trump administration rolls back protections for rare whales off Florida coast

“If you’re concerned about whales being harmed by offshore energy, I’ve got a whale in the Gulf of Mexico I’d like you to meet. The Deepwater Horizon spill killed close to a quarter of the population alone. The Gulf doesn’t belong to the oil industry, the Gulf belongs to all of us. The oil industry is operating there in public waters, with public resources — and mitigating their activities to avoid causing the extinction of a whale species is, in my mind, not a lot to ask.”
