Name: 3D Ocean Farming

Why I like this app: Very exciting technology about ocean farming

Description:

We have all heard and read about the destruction of our oceans. At some point many of us feel like it’s out of control and there is nothing reasonable that can be done, until now. The concept of 3D Ocean Farming is some of the most exciting technology that I have seen in a long time.

Please see the link to the entire article about this topic at the bottom. What follows is a list of facts about 3D ocean farming and the author of this article.

Bren Smith is a high school dropout who spent a couple of decades trying to earn a living as a deckhand on fishing boats on the East and West coasts of the U.S. After losing several jobs and watching the destruction of the oceans and the wildlife first hand, he got involved with 3D ocean farming. His job was never to save the seas; it was to figure out how the seas can save us (while saving the seas at the same time).

Currently, 3D ocean farming produces a mixture of seaweed, Shellfish for food, fuel, fertilizer and animal feed.

Ocean farms are hurricane proof and not visible from the top of the water.

3D ocean farming faces three challenges:

  1. Bring to the table delicious new seafood in an era of overfishing and food insecurity
  2. Transform fishermen into restorative ocean farmers
  3. Build the foundation for a new blue-green economy that doesn’t recreate the industries of the old industrial economy

Currently they grow two types of seaweed, four kinds of shellfish and harvest salt. With over 10,000 edible plants in the ocean, this is only a start.

Seaweed has more vitamin C than orange juice, more calcium than milk and more protein than soybeans.

If we create a 3D ocean farm the size of Washington state, we could feed the entire planet. This farm would require no fresh water, no fertilizer, no feed and no arid land. This would be the most sustainable food on the planet.

These farmers are working with chefs to create new and delicious meals from the oceans.

Each oyster filters 50 gallons of sea water per day of nitrogen which is currently causing dead zones in the oceans.

Kelp soaks up five times more carbon than land based plants.

Kelp could be used to create biofuels. One acre of kelp could produce 2,000 gallons of ethanol. That is 30 times higher than soybeans and five times more than corn. Creating a kelp bed half the size of Maine would replace all of the oil in the United States.

Sea farms would act as storm-surge protection and break up wave action to reduce the impact of hurricanes and rising tides.

They serve as artificial reefs attracting more than 150 species of aquatic life.

Livestock feed using algae could reduce methane output in cattle by up to 90%.

The challenge now is to develop an infrastructure to support this new industry.
