Leatherbacks are the “Texas*-sized” member of the sea turtle species. The largest, they lay the biggest eggs in the highest number of clutches, travel the greatest distances (and to more varied environments — tropical to subarctic), and dive the deepest (like, whale deep, up to 3,000+ ft/900+ m), looking for their favorite food, jellyfish.

Imagine an animal as delicate and water-filled as a jelly, powering such a huge reptile around the world. The Pacific coast of California is one foraging habitat for leatherbacks, which can now find protection within a 16,000 square-mile “critical habitat zone” up and down the state.

This week’s THUMBS DOWN for HAWAII
The bad news for leatherback and loggerhead turtles hanging out around Hawaii is the National Marine Fisheries Service has relaxed regulations, supporting the island’s long-line industry by increasing the number of turtles that can be legally caught (even killed) as by-catch during swordfish fishing.
In November the numbers for leatherbacks “go up to 26, more than a 60 percent increase, and the loggerhead catch to 34, about a 100 percent increase.” (Washington Post Oct 6, 2012). While these numbers seem small, both sea turtle species have suffered major population declines in the last few decades due to fishing, egg and turtle poaching, and ingesting plastics. Female leatherbacks reach breeding age when they are between 7 and 13 years-old. They may lay up to 10 clutches a year, they only nest every 2 to 7 years (2-4 is average). With all they face surviving to reach adulthood, then reproduce, cutting down threats, rather than raising limits on them, seems prudent.
As bad is the by-catch issue, escaped and discarded plastic is arguably the worst enemy of the ocean and its inhabitants. I taped this photo to my back door as a reminder to take cloth shopping bags with me and to watch for plastic-alternative packaging.

This year’s theme: “Youth: The Next Wave for Change”
Young people around the world are tuning in every day to the planet’s stunning and imperiled ocean ecosystems and how we connect to them all. Celebrating World Ocean’s Day, the Association of Zoos and Aquariums (AZA) members are celebrating with programs and events (find one near you).
My contribution to the DAYis sharing information about a critical ocean problem — plastics pollution. Maybe something here will spark you to spread info and ideas, change what you do, or where you devote time. There’s a lot here, but you can come back anytime, read more, follow the links.
I’m lucky to live next to the Pacific Ocean. Today, as part of my volunteer job, I fed bull kelp to abalone and sea urchins in the intertidal display tank we have at ourlocal light house.

But you don’t have to live near the ocean to have the ocean in your life. You don’t even have to live near an aquarium. Go online — look at photos, listen to wave sounds, or watch a video, like this one, where marine biologist, Wallace “J” Nichols, Phd, talks about “Blue Mind –how your brain gets when you’re at the ocean. Then, get off the computer and go outside. Why? Because studies show our brains on ANY nature change for the better. So cool! We knew that, right?
Now that you’re relaxed and mellow from the lovely pictures, let’s dive into the problem.
PLASTICS AND THE OCEAN GYRES
Plastics — all kinds, sizes, shapes, and chemical composition end up as garbage. We know that much. At the Turtle Island Restoration Network “BlueMind” symposium last month I was reminded all oceans are “downstream.” Everything we do to our land, our waterways, even our air, ends up in an ocean — likely more than one, depending on the currents.

A lot of plastic and other human junk has stalled into a floating “island” called the “Great Pacific Garbage Patch” in the North Pacific gyre (or current). The mess twice the size of Texas. More garbage and tiny, broken down plastic bits are showing up in the other gyres, too, swirling in the equivalent of a plastic alphabet soup. Watch Wallace J. Nichol’s TEDx video on the garbage patchand rethinking our oceans and lives in exciting ways.

“The impossible missions are the only ones which succeed.”
—Commandant Jacques-Yves Cousteau.
The scale and cost of cleanup is beyond doable. But there is a way to slow things down. Reduce the waste stream. Hello–that means us. Polar bears don’t drink bottled water or use styrofoam plates and plastic forks at their picnics.
A Few Factoids:
For an extensive look (with astounding photos) of the plastic waste problem worldwide, go toCoastal Care.org. Definitely worth it, but a caution, it may change your life.
The average American generates 600 lbs. of garbage/year. Half is synthetic and ends up in landfills or “recycled.”
Examples elsewhere — an estimated 150,000 tons of marine plastic detritus washed up on Japanese beaches in 2009. Same year. India. 300 tons in one day. Think of Hawaii as unspoiled? Not all of it.

Plastic bagsmake up25% of urban waste that ends in our creeks. Which run downhill — i.e. into an ocean.

Plastic bottle capslikelydon’t go in the curbside bin; they need special recycling. Avena stores and Whole Foods will take them, or go hereto find a drop-off place near you.
About 8% of the plastics we use are “recovered.” 50% to landfills, the rest is re-manufactured or “disappears.” In 2009, the EPA estimated only 31% of all water bottles hit the recycle bin. Is buying bottled water a little nuts, considering the U.S. has the cleanest water on the planet? Cities spend bazillions of dollars every year ensuring our drinking water (you remember, the stuff out of the tap) is safe to drink. Don’t like the taste, get an inexpensive faucet or counter-top filter. Okay, I’m preaching, but really!
“Downcycling”plastics is recycling them into other things like toys, tables, park benches, pillow and coat insulation fibers, etc. Good news is about 1,800 American businesses handle or reclaim post-consumer plastics collected at your curb. Bad news? These re-manufactured products can’t be recycled when worn out. They go in a landfill.
A Berkeley, CAEcology Center reportsays it costs more in labor and energy to recycle than it does to reduce production and use in the first place. From what I’ve read, it’s a lot cleaner for the environment, too.
Plastics take hundreds of years, or more, to break down in a landfill.
The Marine Conservancy estimates decomposition rates of most plastic debris found on coasts stack up like this:
Foamed plastic cups: 50 years
Plastic beverage holder: 400 years
Disposable diapers: 450 years
Plastic bottle: 450 years
Fishing line: 600 years
Let’s back up to the point about plastics production and source reduction
All plastics increase our dependency on fossil fuels (especially natural gas) and create seriously toxic pollution to air, land, and water during manufacturing.Read Diane Wilson’s bookfor an inside view of what plastic production can do to people and the environment at the source. It’s a powerful story about social injustice and a load of motivation to change our ways.
Toxics escape from plastics in landfills, bottles tossed along roadsides, even the teeny, tiny chunks floating in bays and oceans. Plastics pollutants are believed to cause hard-to-diagnose, and easy to dismiss, health problems in living organisms. Including people. Especially the young.
Marine mammals and fish die horribly from entanglement or eating plastic that looks like food.
“If I find one more stinkin’ plastic bag in my ocean…” my favorite shopping bag by Eco Maniac Co.
I’ve trained myself to the cloth-shopping-bags-in-the-car thing, I’ve bought reusable veggie/fruit bags or reuse plastic ones — some still stick to my fingers no matter how hard I try to avoid them. Now I’m paying attention to what I pick up when I shop. What’s it made of? How is it packaged? Is there an alternative with less or no outside wrap (bulk bin)? Most of all, do I really need it? That’s a tough one, sometimes. I do more charity “gifts” on birthdays and holidays — no more gift wrap to throw away and MOST of my family and friends still love me! Giving a few bucks to plant trees in urban neighborhoods is good for neighbors, cleans the air, AND helps oceans!
And how cool is this? There’s an Android “Marine Debris Tracker” appfor people in Georgia, South Carolina, and North Carolina who want to help track marine debris washing up on their beaches. The project is a joint venture between NOAA and the Southeast Atlantic Marine Debris Initiative (SEA-MDI) out of the University of Georgia Faculty of Engineering. I want one for California! Update: use the app anywhere in the world.
Also,NOAA’s Marine Debris Programhas a 1 page download explaining garbage patches. Think about what you can do to reduce the load–seriously. Print it out and pass it along.
My daughter is a big fan of singer Jack Johnson. Now I’m impressed. He made sure his 2010-11 “To the Sea” concert reduced its environmental footprint. His article about it is on Ocean Conservancy’s web page, or go toAll At Once for the figures.
Here’s wishing you a fabulous, Blue Mind, World Oceans Day! Post a comment on how you’re planning to celebrate our magnificent gift from our big, blue marble — and your gift back at it. Peace.
