Every year the earth loses about 0.01%-0.1% of its species. The numbers may seem small, but if we have roughly 100,000,000 species on earth, that's a minimum of 10,000 species gone each year! Some of these species are lost to natural causes (climate change, disease, ect.), but a lot of them are lost to humanities cruelty toward animals. Just because humans are intelligent beings doesn't mean that we have the right to hunt down and slaughter endangered species! Before we know it, the food chain will be collapsing and more and more species will be going extinct each year. Many organizations are founded to help endangered and dying  species, but the real change will happen when the people selling endangered animals to be killed realize the damage they are doing to their home planet. Hopefully humanity will make the right choice soon and start helping our animals and their homes, otherwise the earth is going to be in big trouble soon.
