Greenwave is a non-profit that is trying to come up with an alternative food production idea.
What is Greenwave’s idea?
Greenwave plans to grow seafood – seaweed, oysters, mussels, shellfish, and scallops on ropes that are anchored to buoys and hang down 6 feet below the ocean surface, but still way above the ocean floor.
Here is what they say on their website, “Our polyculture vertical farming system grows a mix of seaweeds and shellfish that require zero inputs – making it the most sustainable form of food production on the planet – while sequestering carbon and rebuilding reef ecosystems. Since our farms sit below the surface and leverage the entire water column, they produce high yields with a small footprint. Our crops are used as food, fertilizer, animal feed and more. And, our farms are open source: anyone with 20 acres, a boat, and $20,000 can be up and running within one year.”
- The “farming” is below the ocean surface and so doesn’t need any land.
- Seems to be cost-effective, the farmers don’t need to “own” the land.
- No fertilizers or pesticides.
- High yields of seafood, which is healthy.
- Is there this large a demand for seaweed and mussels? Possibly not, but we know there is a shortage of sustainably grown pesticide-free food and this can fill the gap.
Here’s an amazing Vimeo ad from Greenwave that shows you a “visual” of how this works:
