A team for overfishing
By- Leonardo Decaprio.
He has donated millions over the years to preserve ocean life aswell as raise awareness for it using his high media profile so I can see no reason not to have him in a team for overfishing as he can contribute money and awareness for it.

Chris Hemsworth he is also a big star and is shown to have connections to groups that help preserve our so by having him on a team you not only get the support of even more people you are also most likely going to be backed up by other organizations
