"If we want fish tomorrow, we need marine reserves today.
If we want whales tomorrow, we need marine reserves today.
If we want to stop bottom trawling, we need marine reserves today.
For healthy oceans -- we need marine reserves today."

"Dead oceans, dead planet :

We now know that human activity can have serious impacts on the vital forces governing our planet. We have fundamentally changed our global climate and are just beginning to understand the consequences of that. As yet largely unseen, but just as serious, are the impacts we are having on the oceans: we are damaging them on a scale that is unimaginable to most people. Ecosystems are collapsing as marine species are driven towards extinction and ocean habitats are destroyed. Degraded and stripped of their diversity, ocean ecosystems are losing their inherent resilience.
We need to defend our oceans because without them, life on Earth cannot exist."
