Animal conservation is important to promote biodiversity, enhance research opportunities, prevent critical weather events and sustain ecosystem-based economic activity. Failure to recognize the importance of animal conservation efforts may lead to habitat disruption or species extinction in an unprotected area as well as reduced educational and economic opportunities.
Habitat destruction is responsible for most species extinction in plants and animals. When the habitat that a plant or animal lives in is significantly reduced or eliminated, it is difficult for the displaced species to adapt quickly to a new or unfamiliar habitat. This change may negatively impact an animal's survivability, thus reducing the overall population of that animal or causing it to become extinct. Other reasons for species extinction include introduction of non-native organisms to the environment and intentional direct killing by human actions such as through hunting.
Although species extinction can occur naturally, it is important for humans to participate in animal conservation efforts to prevent extinction when possible. This is because a larger number of species helps promote biodiversity. When an ecosystem is sufficiently diverse, it creates economic and educational opportunities through ecotourism and research. Biologically diverse habitats also tend to reach an equilibrium that can help create balance and order as well as keep the local climate stable.
