Nature is vanishing before our eyes. As many as one million plant and animal species are threatened with extinction because of habitat loss, farming, poaching, pollution, invasive species and, increasingly, global warming. Over the past few hundred years, population growth and increased, unsustainable production and consumption patterns have expanded demand for biological resources, which has in turn caused a dramatic loss of biological diversity.
