In the 19th century actions in the U.S. Endangered Species Act (7 U.S.C. § 136, 16 U.S.C. § 1531 et seq.) of 1973, Washington DC, U.S. Government Printing Office along with Biodiversity Action Plan s developed in Australia , Sweden , the United Kingdom , hundreds of specific species protection plans ensued. The Society For Conservation Biology is a global community of conservation professionals dedicated to advancing the science and practice of conserving Earth's biological diversity. THREATS TO BIOLOGICAL DIVERSITY Presently the Earth is undergoing the Holocene Mass Extinction , an era of unprecedented number of Species Extinction s.J.H.Lawton and R.M.May, ''Extinction rates'', Oxford University Press, Oxford, UK Human influence over the Earth's Ecosystem s has been so extensive within the last 10,000 years, that scientists have difficulty estimating the total number of species lost in this era;Paul Ehrlich and Anne Ehrlich, ''Extinction'', Random House, New York (1981) ISBN 0-394-51312-6 that is to say the rates of deforestation, reef destruction, wetlands filling and other human acts are proceeding much faster than human assessment of the Earth's species. The matter of ongoing species loss is made more complex by the fact that most of the Earth's species have not been described or evaluated for endangerment. The IUCN has found that 23 percent of Vertebrate s, 53 percent of Invertebrate s and 70 percent of plants that have been evaluated are designated as endangered or threatened. IUCN Red-list statistics (2006) (The IUCN does not disaggregate endangered from critically endangered or threatened for the purpose of these statistics.) Historically the main threat to biodiversity has been a set of threats generated from the , Deforestation , Overgrazing , Slash-and-burn , urban development, Pesticide use.Paul Ehrlich and Anne Ehrlich, ''Extinction'', Random House, New York (1981) ISBN 0-394-51312-6 | ||
