Understanding Invasive Species and Their Impact on Native Ecosystems

Invasive species are organisms introduced to areas where they do not naturally occur, threatening local biodiversity. Non-native species differ from native species, which belong to a specific region. Overpopulation can lead to resource scarcity, while human activities like deforestation and pollution further exacerbate these problems. Conservation efforts are essential to manage natural resources wisely. Additionally, issues like poaching and overfishing can lead to extinction of species, altering ecosystems and affecting conservation efforts.
