An invasive species is a non-native species that lives in a region. Human activity has accidentally or intentionally

introduced many invasive species into ecosystems. Name two human activities that could contribute to the

introduction of invasive species. Explain your response.

Human travel can lead to an increased risk of invasive species. Native species—both animals and plants—can stow away on cars, trains, boats, and airplanes that bring them to another ecosystem. Climate change also can play a role. Human activity causes increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn creates an increase in global temperatures. Because all species are adapted to a specific climate, climate changes can result in non-native species spreading into other ecosystems.
