The Great Lakes ecosystem has been severely damaged by more than 180 invasive and non-native species. Species such as the zebra mussel, seen here, the quagga mussel, round goby, sea lamprey, and alewife reproduce and spread uncontrollably. It is extremely difficult to control the spread of an invasive species once it is established, which makes prevention the most effective way to deal with organisms that have not yet entered or become established in the Great Lakes.
What is one of the most effective ways to stop invasive animal species from entering the Great Lakes ecosystem?
a
Making an extensive invasive species collection record for the Great Lakes region.
b
Giving presentations to schools throughout the state so students can share this information with their parents.
c
Inspecting entering boats to stop the inflow of invasive species into the Great Lakes.
d
Using effective biocides to kill the invasive species.
