Three quarters of the world's oceans are already officially over-exploited or fished right up to their limit.
There are literally too many boats taking too many fish, often by methods that are damaging to both fish populations, other marine wildlife and ocean habitats. Once considered inexhaustible, our oceans are now in a state of global crisis, and they really need a break.
The good news is that we can lessen our impact on our oceans by choosing our seafood wisely. The fish you choose directly affects the health of our oceans.
