Chasing Coral

Coral reefs are the nursery for all life in the oceans, a remarkable ecosystem that sustains us. Yet with carbon emissions warming the seas, a phenomenon called “coral bleaching”—a sign of mass coral death—has been accelerating around the world, and the public has no idea of the scale or implication of the catastrophe silently raging underwater.

    This is very powerful. The people who worked so hard to put together this documentary did a wonderful job at raising awareness of the impact of global warming on coral reefs. Chasing Coral is informative and persuasive at the same time. It's brilliantly constructed and powerfully told. The filmmakers managed to capture the beauty of the sea and the shocking truth about a massive coral bleaching event that's already become a nightmare for not just marine life but humans as well. Make sure you sit through the entire end credits too.

    "Do we need forests? Do we need trees? Do we need coral? Or do we just sort of live in the ashes of all that?"

    The more aggressive documentaries about nature don't do it for me. The increasing ferocity of storms, rising sea levels, the destruction that's ahead. That's all well and scary, but it's also bleak to such an extent that I feel numb to it. So we're all gonna drown, tell me something I don't know. It's more than we deserve.

    Chasing Coral isn't angry, it's just disappointed. What a weird phenomenon for this brightly coloured jewel of the sea to bleach en masse over the last few decades having never done so before. It doesn't take long to work out that the cause is rising sea temperatures.

    Rather than show violent scenes of Mother Earth retaliating against her disrespectful inhabitants, Chasing Coral is like that part of the Oscars where we remember everyone we lost over the last 12 months. It's a feature length documentary of our world dying.

    The visual work here is astounding. Almost immediately you learn to associate whiteness with death. They try to find where this is happening, then they show you what coral should look like, and they humanise the coral too. They show that it's alive, and knowing that it's alive makes its death all the more upsetting.

    The point that got me was when the corals begin to glow. Some corals do glow, and in shallow waters it's often the tips, the parts closest to the sun. It acts as a sunscreen. Here, dying, the entire coral glows like a beacon signalling the last throes of life. Covering itself in its own sunscreen, it's a mostly futile effort to ward off the heat. It's a dramatic death, demanding attention.

    As with most documentaries of this ilk, it ends on a positive note. We can change! Otherwise, this would be one bleak watch. It works best that way, though. It's a documentary of our home dying, and the cause spreads like a self-inflicted cancer.

    A lot of these films focus on the human impact, of how more powerful storms will wash us all away. Maybe it's that selfish humanity that was lost on me - don't do the crime if you can't do the time. But this is about what's happening around us, how it's fighting to survive, and how it's losing. And that worked for me.

    If you'd told me two hours ago I'd cry over a documentary about coral I would have laughed you right into the sea. But those panoramic shots of once bustling waters filled with life and colour now dead and pale are worth crying over.

    When I logged into Netflix the other day an ad started playing showing the most beautiful underwater photography and I knew I had to watch it. So I eventually pressed play and, yes, it was beautiful.

    In the beginning.

    I admit I was very unaware of the current coral bleaching going on around the world due to warmer ocean temperatures. Our colorful vibrant coral, the animal that cleans our ocean and provides homes for fish, are losing their color and turning completely white as they are reduced to their skeletal frame.

    The doc becomes very sad as you see the filmmakers and scientists spend so much time with the coral, dedicating their every day to researching them, just to see them die a little more each day.

    It's one of the many evidences of climate change and I hope more people click play on this doc because it's scary to see our world changing so fast. 29% pf the Great Barrier Reef died out in just the year 2016 alone. And it's going to get worse.

    A MUST WATCH documentary.

    A thoroughly depressing look at the disruptive effects of rising sea water temperatures. Chasing Coral was not what I had originally pegged it to be (a light hearted expedition under the sea) which is my error for going into it blind, but I'm glad it was what it was all the same. Great timing given hurricane season; we get a video education on our potential doom, just before meeting our potential doom!

  • ★★★★ review by Allyson on Letterboxd

    This is devastating. To learn the details of how these organisms are dying off is absolutely crushing. But this film does more than just flood you with facts and statistics. It led me to share Zack's admiration of these radiantly striking creatures. I fell in love with them. I have a whole new appreciation and fascination for their beauty and complexity. So it hurts to know they are almost helplessly fading away.
