The Earth's population keeps growing, but unfortunately for us, Earth itself is staying the same size. Seems like it might be a problem someday, doesn't it?

A possible future solution? Move to Mars!

There's no life on Mars today mainly because it's far too cold. To make it habitable, we'd have to warm it up.

But how?

Getting Our Hands Dirty
by Trip Jennings
Expedition Granted Competitor

Wow, this contest has been lots of fun. I've gotten to tell lots of people about issues that I'm very passionate about, I've gotten to reconnect with old friends by asking them to vote for me on Facebook (woohoo!), and I've gotten to laugh at myself in some very silly videos. More than anything it has gotten me excited and inspired to go deep into the Congo jungle and into risky situations to protect elephants.

Now, however, the real work begins. Now that we know for sure we're going to collect elephant scat, it's time to get down to business. It's time to fundraise, get permits, and figure out the nitty-gritty of exporting elephant poop from a country like the DR Congo. It's time to get our hands dirty.

You can help! We'll be launching a preliminary project website on Thursday aimed to educate people about the devastating status of the ivory trade and about our project. You can get involved by going to our website and helping spread the word.

[Starting Thursday, Trip's website can be accessed here: www.StopIvoryPoaching.org]

Over the last month, I've gotten some interesting questions. One that I like lots is, "Are you more passionate about protecting elephants or the habitat they live in?" I'm not really sure of the answer to that question... certainly, you can't have forest elephants without forests, but can you have forests without elephants? Here's a great article that says, probably, but central African forests without elephants would be like Manhattan without any vehicles. Hard to imagine huh?

Working at National Geographic, I get to see some really amazing photos.

But Expedition Great White really captured some unbelievable shots of a great white shark. It's astonishing to see these giants out of water.

Bringing Back the Ocean
by Ben Horton
Expedition Granted Competitor

For most of my life, the ocean has only been a few steps away, and for me it's always been a given that I could go exploring and see something beautiful on most days. Every day after school, my parents would pick me up and we'd head out in the boat to explore the reefs around my home in Bermuda.

What was once a given for me, has become rare. The fish are disappearing, the coral is bleaching, and the ocean is dying. I just spent two weeks on a remote island that should by all means have been swarming with sharks, grouper, snapper, and alive with coral. Instead, there were no sharks, the other predators were all but missing, and the coral was bleaching out, dying.

There is one thing I don't think people understand about the work that I'm doing. I'm not just trying to "save sharks," I'm trying to do my part to save the ocean that I remember from my childhood. Sharks are just the vehicle, the means to show what's happening to our planet.

At least in my opinion, they are the most important species we have in the ocean, and are one of the first species to be affected when we are doing something wrong. In a way, they represent the entire ocean. When sharks start disappearing, it won't be long until the ocean that I grew up in is no more.

Sadly, the sharks are disappearing, and the ocean that existed when I was a child is gone.

But it's not too late to bring things back to how they were. That's not to say it won't take time. Many of the species that we've all but obliterated reproduce very slowly, and continue to grow over many, many years. This is not something that we can just put money into and hope for the best. There is no debt to pay to nature that we can pay back in carbon offsets, or by signing petitions.

The changes we need to make start at home, and they grow to encompass our lives, and in the end, we hope that they will inspire others to take the same steps that we took.

Today, I started making plans to go back down to Costa Rica and meet with the scientists that I'll be working with when I do my Rio Sirena project, which has become a small part to a much larger project that I have in the works. There will be no grant for this one, most likely no credit either. But in the end, this is something that needs to happen, and I'm going to do my best to make it happen.

Letting Nature Run Wild
by Ben Horton
Expedition Granted Competitor

Last night I went to an ILCP award dinner to honor James Balog, a conservation photographer who has found a way to truly use imagery to its full potential. There were perhaps 30 of the worlds greatest conservation photographers and other scientists that we all know by name, like Jane Goodall and Sylvia Earle. When I'm surrounded by these people sitting at the same table two things happen. First, I feel a great sense of pride to be sitting with people who have accomplished so much. Second, I realize that I still have a long way to go before I'm REALLY sitting at the same table as these people. In times like this, I just sit back and shut up.

Somehow I ended up sitting next to Sylvia Earle this morning on my flight back from Mexico. For those of you who don't know who she is, she is a legendary marine biologist, and an explorer at National Geographic. She is probably one of the most powerful voices in marine conservation that we have right now. Talking with Dr. Earle, who is so passionate about her cause, made me consider my own goals, and why I'm a part of this competition.

This competition isn't about winning or losing. (That's what I'm supposed to say right? Cause I'm losing.)

For me, and I think for Trip, this is about getting our projects, and the fact that we do projects like these, out into the public eye. Don't get me wrong, I'm not throwing in the towel. I'm going to fight for every little percent of the vote that I can get, because to me, each percentage point on either side of the competition means that we have reached someone with our cause.

When I see my vote rise a few percent points, I see that as a new person coming to the website reading about our projects. This is the main reason we are doing the projects in the first place, right? To show humanity the things that need saving, or protection, because it is humanity itself that is doing the damage.

Somebody is out there buying elephant ivory still, and there are still millions of sharks killed just for their fins, because somebody is paying $400 a pound for the mythological properties the fins supposedly have.

The feeling I have felt slowly forming inside me, is that for some reason people have gotten the idea in their heads that we are the stewards of the planet, the caretakers, that the planet is ours. For some that means that we can take what we want from it, and for others it means that we must do our best to manage it. I wouldn't say it is a revelation, perhaps more of a way of looking at things, but I have come to the conclusion that we are mostly incorrect in thinking this. We need to let nature be nature. We need to have places where the human hand is removed from the equation.

We need to create places where the natural world can be what it is, wild, unrestricted, and unbridled. We also need to make sure it stays that way. That's why I am fighting so hard, not to win this competition, but to get as many people as possible to come to the website and vote. To use it as an excuse to promote the efforts that Trip and I are making to do some good for the natural world. To pick up the torch that people like Sylvia Earle have been carrying for so long.

I have a feeling that if I can reach enough people, this marine reserve I'm trying to help create will be actualized. When this protection is in place, it will be somewhere that we can let nature run wild, unrestricted, and unbridled.

Meet Team Elephant
by Trip Jennings
Expedition Granted Competitor

There is simply no way this type of project could be pulled off without a solid team containing a diverse array of skills both in collecting sound scientific data and in creating compelling media.

We have four people heading out into the field and one amazing biologist working with a team in Seattle to utilize our data. In order to succeed our field team has to be able to survive in the jungle, produce high quality media, do legitimate scientific work and - possibly most important - to leverage our media and data to create real change and protect elephants.

On nearly every project I'm involved with, I work with Kyle Dickman and Andy Maser and for this project, we're teaming up with Joe Riis for the field team.

JOE RIIS

Joe is a biologist by training but a wildlife photographer by profession. He specializes in remote imaging, setting out cameras for weeks or even months to get the perfect image. In his words: "I specialize in remote camera trap photography, which enables me to shoot close-up wide, angle photos of wild animals without human disturbance. It's like seeing through the eyes of a wild animal. I'll be setting up elephant video and photo camera traps, as well as photographing the expedition. And, of course, collecting all the elephant scat that I can fit into my backpack."

Joe's dedication to conservation is not in question. He spent the last three years living in his truck and documenting Pronghorn migration in Wyoming and Montana, using his images to advocate for conservation.

"This expedition is absolutely fascinating to me because it is two-fold. We are addressing both the demand and the supply of elephant ivory, leveraging sound science with compelling media. We collect scat that helps identify poaching hot spots and limits supply, then we photograph and film our experience with these incredible creatures, educating and inspiring our own culture to curb demand for ivory."

ANDY MASER

First off, Andy can carry a backpack a long way. That's going to be important when we've been trudging through the jungle for weeks with backpacks full of crap. That said, it's in the media realm that Andy's true skills shine.

We've worked together on video projects accepted to a long list of film festivals, which have even won a number of awards. He's a great camera-person and has lots of experience getting in - and out - of very difficult shooting situations, a must for this protect.

When we return from the field, the real work begins. One of our top goals for this project is to use social media, from blogs, to video on demand, to facebook and twitter, to reach an exponential audience in addition to major media outlets in order to educate and curb demand for ivory.

"The fact that these elephants are quickly on their way to extinction is not widely known, nor is their greater role in the critically important forest ecosystem in which they thrive. This expedition will allow us to show us that taking action at home will help ensure the survival of this iconic species."

KYLE DICKMAN

Kyle is also tough as nails and an amazing writer. He's written for Adventure Magazine, Outside Magazine, and the Smithsonian covering expeditions like this all over the world. He'll be using his writing skills to publish articles and news pieces far and wide raising awareness to the plight of elephants and the rapid rate at which they are being killed for ivory.

He was a hotshot firefighter on a crew with a strong reputation for years before becoming a full-time writer and I think that made him physically incapable of complaining. We could be sunburned, drenched, exhausted with our feet rotting from trench foot and he'd still be writing on his waterproof pad the details of the sunset and the name of that last village.

"Expeditions are a mixed bag. Sometimes, things suck. The easiest thing to do is just keep your head up and go to work," Kyle says. "Plus, for better or worse, the suffering seems to make them more memorable."

TRIP JENNINGS

Where do I fit in? Well first and foremost it's my job to design the project and put together a team that will succeed. That finished, I will be raising the funds, building a base of support in the US, and most importantly making sure that we collect usable DNA data for Dr. Wasser.

When we finally do make it into the field, I am in my element. I love traveling in the deep jungle, far away from industrialized civilization, and it's hard to get much farther away from modern civilization than the jungles of the Congo Basin. Shooting compelling video of important scientific and conservation work is my passion. Nothing makes me happier than documenting a pristine jungle and intact - albeit endangered - animals like elephants. I think it's also important, crucial even, to document the devastation, the deforested land that was once habitat and sadly, the elephants that we were not able to protect. For me it's a cathartic and healthy part of environmental journalism to document the carnage, the reason for us, and the audience of our media, to keep fighting to protect wild places and the amazing creatures that live in them.

I hope you'll help this project succeed by voting for team elephant every day!

Just in time for Halloween, there's another twist to the disembodied feet mystery. But this is no ghosts and goblins mystery. Theories of serial killers, plane crashes and tsunami victims have been suggested.

Just this past Tuesday 10/27, another sneaker was discovered washed ashore in British Columbia. Not familiar with the case?

In late 2007, a 12-year-old girl found something unusual along the shores of an island in British Columbia: a male right foot inside a shoe that had washed up with the tide. Six days later, another foot in a sneaker had washed up, this time forty miles south. It was not the missing half of the pair however, but a different right foot. Over the next fifteen months, four more feet washed ashore in the region.

Now another sneaker has been found. Though it has not been confirmed it's related to the others, it does add another clue to this bizarre mystery.
