Endangered species
Endangered Species
Endangered species (/ɛnˈdeɪndʒərd ˈspiːʃiːz/), from the Latin endangerium meaning "in danger" and species meaning "kind, sort", are any species of organisms that are at risk of extinction due to a sudden rapid decrease in their population or a loss of their critical habitat.
Previously, any species of plant, animal, or other organism that was threatened with extinction could be called an endangered species. The need for separate definitions of "endangered" and "threatened" has arisen because of the many conservation laws and regulations, such as the Endangered Species Act.
Causes
The causes of species endangerment are varied, but they all have a direct or indirect link to human activities. The primary causes include habitat destruction, overexploitation, climate change, pollution, and invasive species.
Conservation
Conservation biology is the scientific study of the nature and status of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction. It is an interdisciplinary subject drawing on natural and social sciences, and the practice of natural resource management.
