>> The Update Aquatic fills the waters of Minecraft with life. What if there was a way we could regrow coral and bring the same life back to our oceans. >> Coral reefs are one of the coolest things you're going to come across in the ocean.
They're like a combination of rock, animal, and plants. The biggest threats to coral reefs are climate change, overfishing, and pollution. I often say they're sending out SOS signals for our planet.
>> Cozumel used to be a forest of elkhorn and staghorn coral reefs right up to the surface of the water. What we see now maybe has less than one percent of the corals that used to be there. >> One of the things that is spreading is this idea of restoring coral reefs, so in places where the reefs have been degraded, we grow baby corals and we outplant them.
>> For Coral Crafters, we collaborated with the creators of a technology called Biorock. >> Biorock is a process by which we grow structures in the sea. It's built out of ordinary construction steel like rebar.
What we do then is we apply a low voltage trickle electrical charge. The electrical current causes limestone minerals to go on top of the steel. What we discovered right away was that we got corals to grow many times faster than normal and we're growing them at record rates.
>> For this project, we asked our community to design Biorock installations that will grow off the coast of Cozumel. StacyPlays build a design chosen by her followers. >> A couple of my viewers suggest I might actually build a mermaid wolf.
>> LogDotZip's design was decided by the worldwide community. >> So, here's the start of the eggs. It's still a work in progress.
>> Rabahrex worked with students in Monterrey Mexico to build the final structure. [FOREIGN] >> Oh my god, the passion. All the teams won my heart.
I was amazed. I'm very happy to be part of this challenge and this project that has a lot of happiness inside of it. [FOREIGN] >> My first experience on a coral reef, what it felt like to me was this dream world, and I think with Minecraft it's sort of the same thing you have all of this space to really create your own dream.
This particular project is a way to take those dreams and turn it into a reality back in the real world. >> Together, we can build a better world one block at a time.
