environmental impact of invasive species

Invasive species are non-native organisms introduced to new environments, often causing harm to local ecosystems. They can outcompete native species for resources like food and space, disrupt food webs, and alter habitats. This leads to a decline in biodiversity, as native plants and animals struggle to survive. Invasive species can also introduce diseases and change ecosystem processes, affecting everything from soil health to water quality. Overall, they threaten the balance of ecosystems, disrupt human activities like agriculture and fishing, and can lead to significant economic costs in managing their spread.
