Natural selection is a natural process that drives evolution and does not pose a threat to biodiversity.

Invasive species are non-native species that have been introduced into an ecosystem and cause harm to native species and the environment.

Sea otters are keystone species because they prey on sea urchins, which helps to maintain kelp forests. Kelp forests provide food and habitat for a variety of marine organisms.

Endangered species are species that are at risk of extinction due to factors such as habitat loss, climate change, and overexploitation.

The California condor was once on the brink of extinction, but thanks to conservation efforts, its population has rebounded and it is now considered a conservation success story.

Ecological restoration is the process of restoring a degraded ecosystem to its natural state, including its biodiversity and ecological processes.

National parks, wildlife sanctuaries, and biosphere reserves are all examples of protected areas, which are areas of land or sea that are designated for conservation purposes.

Mitigation is the process of reducing the impact of human activities on the environment, such as by reducing greenhouse gas emissions or protecting forests.

Using renewable energy sources, reducing waste, and conserving water are all examples of sustainable practices that help to reduce the impact of human activities on the environment.

Conservation education, environmental education, and sustainability education are all terms used to describe the process of educating people about conservation issues and promoting sustainable practices.

World Wildlife Fund, The Nature Conservancy, and Sierra Club are all examples of conservation organizations that work to protect biodiversity and promote sustainable practices.

Community-based conservation, participatory conservation, and collaborative conservation are all terms used to describe the process of involving local communities in conservation efforts.

Project Tiger, Project Elephant, and Project Snow Leopard are all examples of conservation success stories in India that have helped to protect these iconic species and their habitats.

Climate change adaptation, climate change mitigation, and climate change resilience are all terms used to describe the process of reducing the impact of climate change on biodiversity.

The recovery of the bald eagle population in the United States, the reintroduction of the giant panda to the wild in China, and the protection of the rainforests in the Amazon Basin are all examples of conservation success stories in the world.
