I may be an ocean advocate, but I have been terrified of sharks for my entire life. So, on a recent trip to Hawaii, I decided to finally confront my fear and signed up for an ecotourism shark cage dive. When I gathered the courage to lower myself into the cage, I immediately came face to face with a large Galapagos shark and was shocked by the sense that an intelligent being was looking back.
Its movements were smooth and graceful as he glided tranquilly past; his gray, sleek body standing in beautiful contrast against the cobalt blue water as I began a tremendous discovery process that would change my view on sharks forever. After such a personal experience, I came home needing to learn more about these animals I’d feared for my entire life. What I discovered was that not only were sharks in trouble, but surprisingly that their disappearance would deliver a serious cost to us as well.

Underwater statues are fun to look at, but can they really function as an artificial reef? Credit: Jim Bahn flickr stream
Two of my favorite pastimes are visiting art museums and exploring new underwater habitats. But combining the two can be environmentally risky. That’s why there are a couple of things that concern me about Jason deCaires Taylor’s project in Cancun, Mexico, that has placed 500 statues as an underwater tourist attraction. Here are a couple questions I asked myself after hearing about the site.
1. How does it help ocean health?
The artist, Jason deCaires Taylor, mentions that his statues at Museo Subacuático de Arte (MUSA) are being covered with coral and algae, but this does not necessarily mean his statues are helping the ocean. When implementing artificial reefs, the placement of human-made structures onto the seafloor, you need to have biological goals in place. This ensures that your artificial reef, or 500 statues in this case, contains organisms that can co-exist in a way that mimics the natural food web over time instead of throwing it out of balance.
2. Are the statues secure? Continue reading »
High on my bucket list: a swim with sharks. And if I’m going to be up-close-and-personal, my first pick is to be introduced to the world’s biggest fish, the whale shark.
Nicknamed “dominoes,” these guys may grow to more than 65 feet over their long lives. To give you some perspective, recall the feeling you get standing next to the bulk of a school bus, typically less than 40 feet long. Now imagine being in the water with a whale shark. I’m thinking the wow factor is huge, especially after viewing this video.
The IUCN lists these gentle giants as “vulnerable.” Long sought after for their fins, (finnning has caused many shark populations to plummet), the good news is that whale sharks are now a growing draw for tourists. And there’s quite an emphasis on responsible practices when it comes to tours that offer swimming with whale sharks.
Hopefully, increasing awareness and appreciation of both their role in the sea and their ecotourism value for many coastal communities will give a new meaning to the term “domino effect,” and these beauties will thrive long into the future rather than facing a cascading population decline from finning and other threats in their ocean home.
I have to admit that I’m attracted by the fact that they’re slow-moving in a dreamy sort of way. And that they live in beautiful warm waters like Mexico’s Sea of Cortez. Besides, who can resist meeting a critter with polka dots? I think I’ll be moving this item up on my bucket list.
