The impact of climate change on invasive species and ecosystems

This year's Earth Day theme is "Protect Our Species." Climate change is putting millions of species at risk of extinction, and others are being forced to migrate to other habitats. Last October, the CBSN Originals team investigated invasive species, which occurs when non-native organisms enter an ecosystem and cause harm. There are thousands of invasive species in the U.S., some caused by human activity and others by climate change. CBSN Originals supervising producer Matt Morrison joined CBSN to discuss the growing problem.
