Could you imagine a world without tigers, giant pandas or rhinos? What a paler place that would be. A surprising number of animals are considered critically endangered and on the verge of extinction. If we want these animals to be around for future generations, we cannot hesitate to make efforts to help them. Rhinoceros – Unfortunately, the white, black, and Javan rhino are all on the critically endangered species list. The Indonesian Javan rhino is in a particularly poor state: there are fewer than 60 examples left in the world. There are approximately 3,000 black rhinos. Illegal hunting constitutes their main threat. Giant Panda – The giant panda is native to China, Burma and Vietnam. High estimates say there are fewer than 2,000 left in the world, low estimates say 700. The main reason for their population decline is poaching and habitat loss. Sumatran Tiger – This beautiful big cat is native to Indonesia. Over the past fifty years, its numbers have declined significantly due to hunters and the destruction of Indonesia's forests. More than 80% of Indonesia's forests have been cut down and, sadly, more is being lost every day. Thanks to strict hunting laws, Sumatran tiger numbers have slowly increased over the past decade. However, their population is still less than 600. Siberian/Amur Tiger – The Siberian tiger is the largest cat in the world. They are found in Russia. There are around 400 Siberian tigers in the world today. While that doesn't sound like much, it's a marked improvement over the 40 who lived just 50 years ago. Polar Bear – Polar bears live throughout the Arctic. At one time there were several hundred thousand but due to excessive hunting; there the numbers fell to fewer than 25,000. Mountain gorill... middle of paper...... hem; today their numbers have increased to 500. Unfortunately, their habitat is so diminished that even if their numbers increase, it will not be able to support more than 2000. Their plight is due to habitat loss and poaching. the leopard comes from eastern Russia, Korea and northeast China. It is the rarest feline in the world and is “critically endangered”. There are only 30 to 40 left in the world. Unfortunately, many beautiful animals on this planet are on the verge of extinction. Only serious and immediate changes will make a difference in their survival. We will all have to work together to save these species and ensure that they no longer suffer their fate. Although it is too late for those we have already driven to extinction, it is not too late for those who are critically endangered. It's up to us to ensure they will be there for our future generations.
