Scientists estimate that the full biodiversity in the world is among 10 million and a hundred million species. of those, simply over 1.6 million and counting have really been catalogued and defined. One percentage, or 16,306, of these species are threatened with extinction, approximately one-fifth of them significantly. Of this workforce, a few have vanishingly small populations within the double or unmarried digits. a number of species, together with the Pinta Island substantial tortoise and the Yangtze vast softshell turtle, sit down squarely at the border of extinction within the wild with a inhabitants of one.

Leslie additionally tells tales of hopeful development, as many of the rarest of the infrequent are again from the edge of extinction in the course of the committed efforts of individuals round the world.

There’s only so much food to go around any ecosystem, and in the Primorye region the cupboard is getting bare as poachers compete directly with the leopards by overhunting deer to the point of scarcity. This lack of prey is thought to be one of the greatest barriers to the population recovery of the Amur leopard. It’s hard to rear young when you can’t feed them. It is even more difficult when local villagers set fire to the forest to create better growing conditions for a type of edible fern that is popular in the regional cuisine and sold at market.
So, too, are Przewalski’s horses, though I’ve only seen them in zoos, where they are everyone’s favourites. Lemurs, too, are appealing. Most mammals are, but being cute isn’t enough. What unites the creatures, both large and small, in this book is where they live. The seven billion of us are destroying our forests and grasslands—almost all terrestrial habitats—and making a mess of rivers, lakes, and the ocean. Habitat destruction is the major cause of species extinction. Not all habitats are equal.
With only 20 gibbons left, even the death of one animal is devastating to the species. Because all of their typical lowland forest habitat has already been destroyed, the reserve is at a less fertile, higher elevation than gibbons naturally prefer, and they must work harder to get enough food. The human population continues to grow, and the collection of firewood and clearing for farming is fraying the edges of even this last sanctuary. With so few individuals left, a severe typhoon, disease, an imbalance in the ratio of males to females, inbreeding, or any number of non-human related causes could wipe out the species.
