Our ocean is precious. It is like the Earth’s circulatory system: it performs numerous vital functions which make the planet habitable. It provides us with food, freshwater, energy, medicine and the phytoplankton that lives in it provides half the oxygen we breathe.

Despite the important role it plays in all our lives, the ocean faces growing threats. One of the biggest is climate change, which results in ocean acidification and rising sea levels, and you can find out a bit more about acidification below.

Now, four years and 15 countries in the making, a new film by Canadian environmentalist and documentary maker Rob Stewart, explores the changes taking place in our ocean and other ecosystems, and calls on us to take action. Richard Branson described the film as "A stunning adventure!"

And it couldn’t have come at a better time. We need to change the way we interact with the planet urgently. We must be stewards of its resources, not tyrannical owners. This year, the world will come together to make a new climate agreement and put in place a set of goals that will guide our future development. We must work to make those agreements ambitious, and to put the ocean at the centre of both.

What is ocean acidification?

As we have been releasing more carbon dioxide into the atmosphere from burning fossil fuels, the ocean has been absorbing approximately a third of it since pre-industrial times. As seawater absorbs the carbon dioxide from the air, it becomes progressiely more acidic. Right now, the ocean is acidifying faster than at any time in the last 65 million years, and possibly the last 300 million years. 

This is a relatively new field of research and there is much to learn, but this change in chemistry has potentially huge implications for ocean life and the services it delivers. Acidification is an additional stress factor for the ocean which is already under immense duress from increasing demand for resources, technological advances, overfishing, pollution, biodiversity and habitat loss, alongside weak governance. In addition, the current extinction rate is roughly 1,000 times faster than the average pace in Earth's history. That makes this the fastest extinction event on record.
