The role of contamination and pollution in endangered species decline

Human activities in the last 100 years have contributed to an extinction rate rivaling the meteor

strike that ended the dinosaur's era. The speed, severity, and taxonomic diversity of the

declining species is a major concern of the world's ecologists. Extinctions are taking place at a

rate of approximately 100 species per day. In 1989, E. O. Wilson projected the loss of species

at more than 20% of the planet's total biodiversity in 20 years. The Nature Conservancy has

complied a list of 20,481 plants and animals within the United States and estimated, within

arbitrary parameters, the persistence of each species. There were 4,325 animals on the list:

2,524 vertebrates and 1,801 invertebrates. Seventy-five percent (1,893) of the vertebrates and

61 percent of the invertebrates (1,098) were secure or apparently secure and could be expected

to persist. The remaining animals (1,334) are likely to go extinct. This poster will discuss the

role of contaminants/pollution in the decline of species. A subset of the pertinent information

represented by the approved Recovery Plans provided data on species response and
