Question | Answer |
How many species per year we are losing | approximately 50,000 species |
Inbreeding | occurs when individuals with similar genotypes, generally relatives, breed with each other. |
Categories of Endangerment | Extinct:No individuals of the species are known to exist today. Threatened:Species have a high risk of becoming extinct in the future. Near-threatened:Species likely to become threatened. Least concern:Species widespread and abundant in numbers. |
HIPCO | Habitat Loss Invasive Species Pollution Climate Change Overharvested |
Habitat Loss | For most species the greatest cause of decline and extinction |
Invasive Species | when alien species spread rapidly across large areas. |
Pollution | Threats to biodiversity from pollution can come from toxic contaminants such as pesticides, heavy metals, acids, and oil spills. |
Overharvesting | ndividuals of a species are removed at a rate faster than the population can replace them. |
Lacey Act | First passed in 1900, the act prohibited the transport of illegally harvested game animals, primarily birds and mammals, across state lines. |
