The Shark-Free Marina Initiative

Their motto is, "Reducing worldwide shark mortality, one marina at a time."

Here are the basics: A shark-free marina does not allow shark to be killed and landed at their facility. Through the Shark-Free Marina Initiative, businesses are able to register as shark-free and mandate that no caught shark is allowed on their docks. In some states, fishing for shark is still legal ( so the initiative also allows businesses to register as shark-friendly. A shark-friendly business asks fishermen to release caught shark, and strongly discourages international shark fishing.

Why do people kill sharks?
Shark fin soup is a traditional Chinese dish served at weddings, symbolizing wealth, power, and honor. An estimated 70 million sharks were caught and traded last year. Due to its cultural importance, the demand for shark fin soup still remains despite having significant impacts on diminishing shark populations. Hawai'i was the first state in the U.S. to ban shark fin soup, and now the Oregon House just passed a bill to ban it. Hopefully other states will follow suit?
In addition to soup shark is prepared in other ways, but soup is the main problem because fishermen will catch a shark, chop off its fins, and throw it back out to the ocean to bleed and die.
Personally, the thought of eating it makes me gag.

Sharks are also being thoughtlessly murdered as bycatch in fisheries. The target species may be tuna or swordfish, but fishing methods are not species specific. Therefore sharks, dolphins, whales, seals, sea turtles, and marine birds are all caught unintentionally.

What will happen if all the sharks are gone?
Total ecosystem collapse. Sharks are a keystone species, and regulate populations of other marine animals such as stingrays and various fish. If the populations of these prey organisms grow out of control, the ecosystem becomes imbalanced. 
I will attempt to explain:
No sharks/top predators --> More prey --> Prey animals eat more smaller animals (like crab/shrimp/scallops/smaller fish) --> Prey populations explode --> Prey populations eat ALL of the smaller animals --> No more shrimp or scallops for anyone (including humans) --> prey populations die --> this trend continues down the food chain until ecosystem reaches zero productivity.
I hope that made sense. Long story short, sharks and other top-predators like tuna and carnivorous whales are incredibly important to oceans worldwide. 

People are beginning to learn that sharks really aren't as dangerous as the Hollywood movies portray them to be. They're actually more dangerous to you if you eat them: shark is known to have high levels of mercury and toxins due to biomagnification

How can you help?
You can do your part to keep sharks on this planet by choosing smart, sustainably caught seafood. Avoid tuna or swordfish unless they were caught with a pole by a local fisherman. Ideally you want to stay away from any fish caught using gillnets, and avoid eating shrimp caught with shrimp trawls!

Bill Nye's Climate Lab!

Find the website here.

Bill Nye the Science Guy has been a hero of mine for as long as I can remember seeing his shows on TV and in grade school classrooms. He's now got this cool new website "Bill's Climate Lab" to show how everyone can make a difference in the fight against global climate change. It's really neat!

At first I thought it would be lots of "kids stuff" I already knew, but it actually has some pretty solid science and I realized it is actually more focused for adults more than kids.
Bill Nye is the coolest, ever!

Human Overpopulation

Wear a condom now... save the spotted owl.

The Center for Biological Diversity was handing these out at ISTS in April. They're condom packages that feature various endangered species and provide information about humankind's overpopulation of Earth and the trouble it has caused for various endangered species. 

Humans are the most populous mammals on this planet, and we consume most of the natural resources available. We cut down trees that may have once been shelter for a tree frog, bird, beetle, monkey, or some other animal. We pollute bodies of water, home to dozens of species of fish, frogs, etc. We develop coastal areas for our own living, and destroy the nesting areas for sea turtles and the habitats of hundreds of other species. You get the picture.

As more and more of us populate the Earth, we are running out of resources for even ourselves. (See post on Earth Overshoot Day) So if you and your significant other are planning on having a hundred kids, please think again. Don't have more than two (to replace you two). Even better, adopt.

Earth Overshoot Day

I found this article on Wikipedia about Earth Overshoot Day or Ecological Debt Day. Basically it is the day each year where the people of Earth enter a period of "deficit spending" of natural resources. Each year the date falls earlier and earlier, signifying humanity's overconsumption of Earth's available natural resources. What happens when we get to Jan 01? How long does humanity have left, really?

Not to scare you or anything.

The Ecological Debt Day for 2010 was August 21; 2009 was September 25.



Time to start practicing sustainability!

How I Reduced My Plastic Consumption Today!

This event came in perfect timing after my last post about the movie Bag It.

I managed to get some grocery shopping done today, and the first thing on my list was granola. I was at Whole Foods, my favorite place in the world, and walked down the cereal aisle grabbing a bag of Galaxy Granola—which is totally delicious by the way—realizing that it was in a plastic bag but not seeing anything that I could do about it. So I thought!
On the left is the bag of granola I ended up getting! Same brand as the one on the right but no plastic packaging!

The next aisle over they had rows and rows of chopped nuts, dried fruits, chocolate-covered goodies, grains, and GRANOLA in
self serve boxes, sold by the pound. I literally stood there for 15 minutes deciding whether I wanted to buy the granola in a plastic bag, or scoop out a pound of it myself and not have to waste plastic.



In the end I put the bag back and scooped out some unpackaged granola (SAME BRAND—
Galaxy Granola!!) into a paper bag I was reusing from a previous trip to Whole Foods. It
ended up weighing 1.15 lbs, which at $4.99/lb came out to be $5.73 or something like that. I can't remember what the pre-packaged Galaxy Granola cost (it was around $5). However, a single bag of Galaxy Granola only contains 0.75 lbs of granola (12 oz).

So in the end I definitely paid less for more, and didn't use plastic!

SCOOOORE!
