Blue Heart of the Planet

Blue Heart of the Planet

simone (2)When the weather doesn’t cooperate with my exercise plans I use the elliptical trainer. I’ve been watching TED talks while working out–specifically the series on the Ocean. One of the presenters referred to the Ocean as being the ‘blue heart of the planet’ so on this first day of spring, I wanted to celebrate the Ocean….the one massive Ocean that covers 71% of the Earth’s surface and contains 97% of the planet’s water (NOAA).

We know that the Ocean is the lungs of our planet. Although estimates vary, somewhere between 70 and 80% of Earth’s oxygen is produced by phytoplankton in the ocean. Rain forests and trees are very important and provide the other 20% to 30% of vital oxygen.

Dr. Sylvia Earle reported in one TED Talk that 90% of the Ocean’s big fish are gone. Ninety percent….gone. This is directly the result of overfishing…taking fish faster than they can reproduce.

simoneI was thinking about the interconnection of the Ocean and all life on the planet. Truly, if the Ocean dies, humans will die…unless we learn to breath a mixture of less than 21% oxygen. Divers know better, so do scientists….and physicians. We simply cannot survive on less oxygen…at least not for any length of time.

After watching the TED talks, two stories came to my attention that broke my heart. First, over 200 manatees have died this year due to red tide or an algae bloom in Florida waters. Red tide is caused by a combination of factors that can include warm Ocean temperatures, high nutrient content (from fertilizers and sewage effluent) and low salinity (that might happen after heavy rain). Manatees are endangered and their recovery was looking very good so this is a major setback. You might not care about manatees so why should it concern you? The algae associated with red tide can cause respiratory distress in humans and can make people sick if they eat shellfish or fish that have eaten or been exposed to the algae. That interconnected idea…it’s for real!

The other news was especially difficult to hear and even though it doesn’t involve ocean animals directly, it is a species genetically related to manatees. A story on NPR told of how poachers are killing African elephants in numbers so great that their numbers have been reduced 62% in ten years. A reporter told of witnessing 100 men on horseback rounding up herds of elephants and using assault rifles and grenade launchers to kill elephants for the ivory trade in China. Diplomatic jets from China transport the ivory back where the growing middle class and upper class pay over $1300 a kilo (2.2 pounds).

Can you imagine our planet without elephants? Or manatees? Can you imagine humans capable of murdering innocent animals such as elephants…or dolphins like they do in Japan? Innocent creatures.

The heart of our planet is in danger and not just the blue heart. It seems as though the collective human soul is filled with violence and greed. While listening to the elephant story I sobbed and screamed….I am so angry about human arrogance and greed. We are capable of such love and beauty and at the same time capable of unspeakable acts of violence and aggression.

One of the TED talk scientists spoke of how easy it is to become overwhelmed with all of the horrible things happening on our planet. His suggestion was to do everything you can in your own life and then choose one place or one animal on the planet and call that your project of hope. Support it, educate people about it, study it. If we focus on everything that’s wrong we get depressed, angry…we become ineffective. But if we work on our home life and that one special project of hope, we can continue to be an advocate for positive change in the world.

Now is not the time to give up. It’s not too late. As Sylvia Earle said, “The good news is there’s still 10% of the big fish left on the planet.”

simone (4)May our hearts join together in support of the blue heart of the planet and may there be a collective awakening of love and light. Nothing else will create the change that is necessary for planetary health…of which humans are an important part.
