Global fish stocks are exploited or depleted to such an extent that without urgent measures we may be the last generation to catch food from the oceans. To start turning the tide, fishing quotas advised by scientists need to be respected. Strengthening and expanding protected marine reserves would also go a long way to conserving species. Currently, less than 1% of the ocean is protected, although by 2020, the international community has agreed to raise this to 10%. It is our duty to hold our politicians accountable.
