As human population has surged this century, the population of numerous other species have tumbled, many to the point of extinction. Indeed, we live amid the greatest extinction of plant and animal life since the dinosaurs disappeared some 65 million years ago, which species losses at 100 to 1,000 times the natural rate. But humans are not just witnesses to a rare historic event, we are actually its cause. The leading sources of today's species loss, habitat alternation, invasions by exotic species, pollution, and over hunting are all a function of human activities. Human activities have pushed the percentage of mammals, amphibians, land fish that are in "immediate danger" of extinction into double digits. The principal cause of species extinction is habitat loss-the result of encroachment by humans for settlements, for agriculture, or to claim resources such as timber. A particularly productive but vulnerable habitat is found in coastal areas, home to 60 percent of the world's population. Coastal wetlands nurture two thirds of all commercially caught fish, for example. And coral reefs have the second highest concentration of biodiversity in the world, after tropical rainforests. But human encroachment and pollution are degrading these areas: roughly half of the world's salt marshes and mangrove swamps have been eliminated or radically altered, and two thirds of the world's coral reefs have been degraded, 10 per cent of them "beyond recognition".
