This is the Nine O'Clock News. I'm Catherine Bryce. Conservationists have warned that some of the world's rarest animals could be extinct within months. This means that many young children will grow up in a world without species that are alive today. Zoos and rescue centers are working hard to protect animals from becoming extinct. Sadly, the numbers of some species continue to decrease at a rapid rate.
Habitat loss is the biggest problem for endangered species. All over the world, a large amount of land is cleared for growing crops. This means that a lot of animals lose their homes as trees are cut down and machines dig up the ground. Hunting is also a main cause of extinction in the animal world.
Poachers kill rhinos for their horns, while mountain gorillas are killed for their fur. Although many governments have made the sale of these animal parts illegal, hunting continues around the world. According to the International Union for Conservation of Nature, more than 27,000 species are at risk of becoming extinct. This includes 25% of the world's mammals and 14% of birds.
One mammal that is very close to extinction is the Baquita porpoise. The Baquita is known as the panda of the sea because of the dark circles around its eyes. It lives in Mexico's Gulf of California. The total number of Baquitas has decreased by 90% since 2011 because they are getting stuck in fishing nets used to catch other sea animals.
In 2017, there were only 30 Baquitas left in the wild. By 2018, that number fell to just 12. The Mexican government finally stopped the use of these fishing nets in the Gulf of California in 2015, but it seems that it came too late. The government and conservation groups also designed a plan to use trained dolphins to move the Baquitas to a protected area.
But the plan didn't work, because one of the Baquitas died. It seems they are shy animals that don't do well in captivity. In order to save the Baquita from extinction, conservationists will have to think of another way to protect the last few animals.
