The fossil record tells us there have been five major extinction episodes during the 3.5 billion year history of life on Earth. This one--the sixth--is different because it is the result of human activities: habitat destruction and fragmentation, over harvesting, invasive species, pollution and climate disruption.

The species we are losing make up the fabric of life on earth. Together they form the life support systems that humans depend upon.

The continuing loss of biological diversity is a major threat to the future of life on earth and requires immediate action at all levels.
