7. Lemurs
Found only on the island of Madagascar, lemurs are officially the world's most endangered mammals. Deforestation, climate change and hunting have seen 90% of lemur species slide into the vulnerable, endangered or critically endangered categories. The political turmoil in Madagascar is thought to be largely to blame for the population crash, as poverty has driven up both illegal logging and hunting in order for people to survive. Ironically, the little primates, who are thought to have arrived on the island via little rafts of vegetation over 60 million years ago, are a major tourist attraction to the island, and are definitely worth more to the country alive.
