We can avoid purchsing overfished spieces that are not being managed in a way that ensures recovery. [] We can also creat oceans sanctuaries to protect biodiversity. Protecting the marine biodiversity is important because this will help the fish and mammals return to healthy levels. There is "clear evidence of people's ability to overcome the 'tragedy of the commons' by making and enforcing their own rules for managing fisheries," explains team leader Dr Josh Cinner of ARC Centerof Excllence for Coral Reef Studies and James Cook University, Australia.[] This is important because we can make big progress. if wer are able to enforce our own rules, the the fish populations will have a chance to bounce back. The study's main finding is that co-managment has been largely sucessful in sustaining fishries and improving peoples livelyhoods. [] Many scientists say most fish populations could be restores with aggressive fisheries managment, better enforcement of laws governing catches, and increases use of aquculture.
