BIO205H5 Lecture Notes - Lecture 23: Conservation Biology
Document Summary
Animal species are slowly declining over time due to climate change. Many mammals, birds, and amphibians are already extinct. Many species extinct - documented since 1500. Total of 765 species that are extinct. Things are looking better - not becoming easier. Climate change could drive marine food web collapse through altered trophic flows and cyanobacterial proliferation. Threat of plastic pollution to seabirds is global, pervasive and increasing. We can get better at integrating management of humans and endangered species! We can act before it"s too late - isn"t late yet to fix up the system. We can recognize that conserving biodiversity is not straight forward. They were first listed as endangered in 1966 in michigan and then federally listed as endangered in 1975. In 1982 there was high support for the recovery - fear region, type of community predicted anti-wolf. 1990 - significant differences among farmers, hunters and regions. 2004 - decreasing fear, low support for hunting wolves.
