Today is the 35th anniversary of the signing of the endangered species act by President Nixon. It has been tremendously successful in saving a few species such as the Grey Wolf and the Bald Eagle. It has saved countless ecosystems from further degradation and has helped maintain our biodiversity.
It has continued to be a political and controversial topic since before its initial signing. Just last month our current president launched a last ditch effort to destroy this legislation by removing the requirement for scientific review. The Inspector general even reported that the Interior department directly and indirectly interfered with wildlife science on 15 occasions during the last 5 years.
