Together, we can protect the Gulf of California World Heritage site, home to the critically endangered vaquita. There may be fewer than 30 vaquitas left in the world and we can save them. Ask the Mexican president to take strong action now.

Support for local fishing communities is key to saving the vaquita. Due to lack of enforcement, illegal and unsustainable fishing is decimating the Gulf's once-thriving waters and putting people's livelihoods at risk. It is critical to work with local communities for sustainable fisheries management, including the adoption of gillnet alternatives.

The Gulf of California is home to a spectacular array of wildlife, including vaquita – the world's most endangered marine mammal. Unless the threats leading to the critical decline in the vaquita population are removed, the Gulf of California could be placed on UNESCO's List of World Heritage in Danger. And the world will forever lose this species.

To prevent its extinction, a permanent gillnet ban is urgently needed - together with the development of fishing alternatives, and effective enforcement to halt illegal totoaba fishing and its trade from Mexico to China.

The race to save our planet's vaquitas starts now. Show your support here and be a champion for the Gulf of California and vaquitas, before the world loses this species forever.
