SUSTAINABLE FUTURE
Sunfish or Moonfish, She Gives Me Joy
A tanka. A story about oceans and their efforts to reduce climate change. What gives me joy? I met a sunfish in South Africa

A curious sunfish is floating, waving her fin. And when I call her, she wonders why this Dutchie calls her a sunny moonfish.
This tanka is my poetic way of celebrating the life of a sunfish I met in South Africa. Sunfish are gorgeous! They are funny.
Sunfish are funfish.
This one was waving her fin at me as if to say: “Hey, nice to meet you. How are you doing?” And I responded: “Hello moonfish.”
In my language, Dutch, the sunfish is called a moonfish. Why? I haven’t the slightest idea. Sun or moon, both are round, both are shaped like a sunfish or moonfish...

Sunfish are the most curious creatures. They can weigh tonnes, they are heavy fish. And funny ones. They are like floating fish heads...
The Lungs of the Planet
According to the National Ocean Service (USA), the oceans cover more than 70% of our beautiful planet. They are home to a wide range of animals, fish, seaweeds, and micro-organisms.
The Woods Hole Oceanographic Institution wrote a great research story about oceans and their function on our planet. Here is the link.
When we compare our planet to a human body, often the rainforests are compared to a lung. But just like our body, our planet has two lungs. The oceans are the other lung.
Rainforests and oceans both draw in carbon dioxide from the atmosphere, reducing the gasses in our atmosphere that cause global warming.
The rainforests rely on large trees that grow slowly over the decades. The oceans use microscopic organisms, phytoplankton, for carbon sequestering. Phytoplankton is no thicker than a human hair, but there are billions and billions in our oceans.
The rainforests and oceans follow two different strategies for the same result. Both regulating the amount of carbon dioxide in our planet’s atmosphere.
“Nearly 25 percent of the carbon dioxide in our atmosphere is “pumped” into the ocean, where it converted into organic carbon by phytoplankton at the ocean surface all over the world.”

Teaching our Children
So why do I tell you about my meeting with the funny sunfish? Why does it matter so much to me?
Well, the longer I work within the sustainability field, the more convinced I’ve become that curiosity and care are the main drivers for sustainability action.
Our children are curious. And they definitely care.
So all we have to do is feed their curiosity with wonderful examples of nature’s wonders. Like the sunfish.
National Geographic Explorer Tierney Thys, marine biologist, is perhaps best known for her work tracking massive 10-foot long, 5,000-pound ocean sunfish around the globe.
In the little film below, she tells us about her fascination with the sunfish. And her hope for the future of the ocean.
“That is the most ridiculous fish I’ve ever seen. It looks like a mistake” — Tierney Thys in National Geographic
