By the year 2000, about 73% of the original global natural biodiversity was left. The strongest declines have occurred in the temperate and tropical grasslands and forests, the biomes where human civilizations developed first (McNeill & McNeill, 2003). Natural habitats were converted to cropland and pasture already more than 10,000 years ago in Southwest 100 Alterra-rapport 1718.
