Lionfish are an invasive species destroying the local fauna of the area. What do you suggest be done? Let them eat everything and destroy the ecosystem that's there? The point of the video is to show how trying to control the population is in an effort to SAVE the native species. Lion fish are no where near going extinct and are not NATIVE to the area. How else do you propose the native species be saved once a species like lionfish are already preying on the ecosystem there?
