Summary
Conservation involves efforts to protect and preserve biodiversity by addressing causes of extinction and implementing various conservation methods. It includes controlling invasive species and utilizing assisted reproduction techniques to support endangered species. Organizations like IUCN and CITES play crucial roles in international conservation efforts.
- Extinction — the dying out of a species. Example: Dinosaurs went extinct due to a mass extinction event.
- Biodiversity — the variety of life in a particular habitat or ecosystem. Example: Rainforests have high biodiversity with numerous plant and animal species.
- Assisted Reproduction — medical techniques to aid in the reproduction of endangered species. Example: In vitro fertilization (IVF) used for breeding endangered animals.
- Invasive Species — non-native species that cause harm to the ecosystem they invade. Example: The introduction of rabbits in Australia led to ecological imbalance.
- IUCN — International Union for Conservation of Nature, an authority on the conservation status of species. Example: IUCN Red List categorizes species based on their risk of extinction.
- CITES — Convention on International Trade in Endangered Species, regulates trade of endangered species. Example: CITES restricts the trade of ivory to protect elephants.
