Habitat loss and fragmentation are the leading causes of the current extinction crisis, as they directly reduce the amount of suitable habitat available for species to survive and reproduce.

Sustainable use of resources is not a threat to biodiversity, but rather a way to use resources in a way that does not deplete them or harm the environment.

Extinction is the term for the process by which a species becomes extinct, meaning that there are no more living members of that species left on Earth.

Sea otters are an example of a keystone species, as they play a crucial role in maintaining the health of their ecosystem by controlling populations of sea urchins, which helps to prevent kelp forests from being overgrazed.

Adaptation is the term for the process by which species adapt to changes in their environment, allowing them to survive and reproduce in new conditions.

The California condor is an example of a conservation success story, as it was brought back from the brink of extinction through captive breeding and reintroduction programs.

Wildlife trafficking is the term for the illegal trade of wildlife and wildlife products, which is a major threat to biodiversity and can drive species to extinction.

Protected areas are areas of land or sea that are designated for conservation purposes, and can include national parks, wildlife sanctuaries, and marine protected areas.

Genetic erosion is the term for the loss of genetic diversity within a population, which can reduce the population's ability to adapt to changes in the environment and increase its susceptibility to disease.

Conservation organizations are non-profit organizations that work to protect biodiversity and promote sustainable use of resources, including WWF, TNC, and IUCN.

Invasive species are species that are introduced to new areas outside of their natural range and become a threat to native species and ecosystems.

Habitat restoration projects aim to restore degraded or destroyed habitats to their natural state, and can include planting trees, restoring wetlands, and creating wildlife corridors.

Resistance is the term for the process by which species evolve to become more resistant to pesticides or antibiotics, making it more difficult to control pests or diseases.

Sustainable use of resources involves using resources in a way that does not deplete them or harm the environment, and can include using renewable energy sources, reducing waste and pollution, and practicing agroforestry.

Recovery is the term for the process by which species are brought back from the brink of extinction, involving a combination of conservation, reintroduction, and restoration efforts.
