The marine ecosystem is inseparable from environmental issues on land.
For example the pollution of marine areas such as New Zealand's harbours and lakes is directly linked to run-off from farms.
The health or sickness of New Zealand's marine ecosystems is an indication of the health or otherwise of our environment, and of the kind of environment we will leave for generations to come.
Leaving fish off your plate will not only save the lives of individual fishes, but will also give over-exploited fish stocks a chance to recover to levels that sustain the population and the ecosystem around them.
