A few sobering reads ...



"Natural history is an important science worthy of respect and research dollars. The scientific method and natural history are not mutually exclusive. Wilcove and Eisner believe that the abandonment of natural history by universities will prove to be one of the biggest scientific mistakes of our time."

Article: Natural History is Dying

"Land use and related pressures have reduced local terrestrial biodiversity, but it is unclear how the magnitude of change relates to the recently proposed planetary boundary (“safe limit”). We estimate that land use and related pressures have already reduced local biodiversity intactness—the average proportion of natural biodiversity remaining in local ecosystems—beyond its recently proposed planetary boundary across 58.1%of the world’s land surface, where 71.4% of the human population live. Biodiversity intactness within most biomes (especially grassland biomes), most biodiversity hotspots, and even some wilderness areas is inferred to be beyond the boundary. Such widespread transgression of safe limits suggests that biodiversity loss, if unchecked, will undermine efforts toward long-term sustainable development."
