Definition
Extinction is a behavioral process in which a previously conditioned response decreases or disappears when the reinforcement or pairing with an unconditioned stimulus is removed. In classical conditioning, this occurs when the conditioned stimulus is presented without the unconditioned stimulus; in operant conditioning, it happens when the behavior is no longer followed by reinforcement.
Summary
Extinction is a critical issue that affects the balance of ecosystems and the health of our planet. It occurs when a species no longer exists, which can happen due to various factors, including habitat destruction, climate change, and human activities. The loss of biodiversity can lead to significant ecological consequences, impacting food chains and ecosystem services that humans rely on. Conservation efforts are essential to mitigate extinction rates and protect endangered species. By understanding the causes and types of extinction, we can implement effective strategies to preserve biodiversity. This knowledge empowers individuals and communities to take action, ensuring a healthier planet for future generations.
