The ocean is a pretty remarkable thing, and yet many of us who live inland pay little attention to it. The ocean is responsible for the air we breathe and the rain and snow that replenish our glaciers and irrigate our crops. It also regulates the planet’s climate, sucking up greenhouse gases that would otherwise raise temperatures to truly unbearable levels.
And yet, noisy ships and industrial activities are drowning out the sounds marine species need to communicate and find their way. Rising sea temperatures are transforming healthy ecosystems into baked and barren landscapes. And the ocean economy often seems to focus on how we can pull resources out of the ocean, whether they’re fish, metals or oil, rather than taking a more sustainable approach.
Today at The Conversation Canada — and across our global network — we’re celebrating World Oceans Day and the UN Decade of Ocean Science for Sustainable Development. Follow our international series Oceans 21 to learn more about South Africa’s sharks, seabird journeys, fish farm viruses, the “blue economy” and much more. You can also tune into a webinar on the state of the world’s ocean — and its future.

Sharks grow slowly and produce few young compared to bony fishes. In many cases, this means that their populations are fished out faster than can be replenished if not well managed.
