This podcast episode explores the concept of invasive species and their impact on ecosystems, specifically focusing on the Burmese python in the Everglades National Park and the spotted lanternfly in the eastern United States. Invasive species are non-native plants or animals that can out-compete native species for resources and disrupt the balance of ecosystems. The introduction of these species can lead to the decline of native species, alter the structure and function of ecosystems, and transmit diseases. The episode emphasizes the importance of preventing the spread of invasive species and highlights the actions individuals can take to protect native ecosystems.
