The primary cause of invasive species outbreaks in ecosystems is often human activity, such as global trade, travel, and habitat modification. Invasive species are non-native organisms that, when introduced, can establish populations and disrupt existing ecosystems, leading to the decline of native species. These invaders often compete for resources, prey on native species, or introduce diseases. Their ability to thrive in new environments can be attributed to a lack of natural predators. Understanding the pathways of introduction and the impacts of invasives is crucial for developing effective management and eradication strategies to protect native biodiversity.
