Causes of Biodiversity Loss
This is an excellent discussion of the causes of biodiversity loss. I highly recommend clicking through to the original article.
“Earth continues to hemorrhage biodiversity, according to the latest Living Planet Report. Unfortunately, its authors cannot manage a clear statement of how to stop the bleeding. “You could think of it as a health check for the planet,” says the World Wildlife Fund, introducing its most recent biennial Living Planet Report, “and a prescription for how to help it recover.” As in previous reports, the diagnosis is grim. Since 1970, for the 32,000 populations of 5200 vertebrate species surveyed, average numbers have declined by 69%. If these populations are representative (and there is no obvious reason to doubt they are), that means that for every 10 wild birds, mammals, reptiles, amphibians, and fish on Earth in 1970, only 3 exist today. It is an almost unimaginable loss for such a short period. Read what the WWF should have said” Millennium Alliance for Humanity and the Biosphere (MAHB).
The Primary Benefit of Biodiversity
Naturalists often warn that biodiversity loss is a greater danger to human civilization than climate change. They give a variety of reasons, but the most important is often overlooked. It is soil. Soil is the foundation for all life on Earth. Diverse ecosystems consistently armor the soil against erosion. If diversity declines, chinks appear and admit wind and rain that erode the soil.
