#extinction
"There are over 150,000 species on the International Union for Conservation of Nature Red List. Of those species, over 42,000 are threatened with extinction. On that list are 17,903 marine species that show population declines annually, with over 1,550 on the path to no longer existing. One marine animal is expected to become extinct within the next few years if no action is taken. However, many conservationists, researchers, and scientists believe not enough is being done to stop this from happening. This means that despite the vaquita fighting for their lives over the last several decades, their struggle may have been for naught if serious changes are not made now.

Gillnets in the Gulf of California are not intended to capture vaquitas. Instead, they are used to catch another endangered species, the totoaba fish. While it is illegal to use gillnets in the Gulf of California and fish for totoaba, the nets are still present, and the fish are being caught because there is a substantial payoff for the totoaba swim bladders on the black market. The market is so considerable that a totoaba swim bladder can go for as high as $80,000 per kilogram."
