In the modern world, we tend to think of extinction as the loss of species of animals and plants. Sometimes those species are also the last members of major groups.
One Quarter of World's Mammals Face Extinction. The baiji dolphin is functionally extinct, orangutans are disappearing and even some species of bats—the most numerous of mammals—are dying out. A new survey of the world's 5,487 mammal species—from rodents to humans—reveals that one in four are facing imminent extinction.
Causes of extinction. There are a number of reasons that can contribute directly or indirectly to the extinction of a species or group of species. The primary causes of species extinction or endangerment are habitat destruction, commercial exploitation (such as plant collecting, hunting, and trade in animal parts),...
Yes it does matter if just one species goes extinct because animals and plants depend upon each other, so the loss of one species affects others within that complex web of relationships.
