1. Watch “Can seaweed save the world?”
Seaweed farming can de-acidify the oceans, stimulate fisheries, increase productivity, feed a world of 10 billion, provide us with liquid fuels, paper, building products — even seaweed concrete — and sequester the world’s CO2. So grab a coffee and watch the ABC’s special “Can seaweed save the world?” It’s well worth the 60 minutes, and again covers the math behind sequestering all our CO2 emissions. If you’re a reader not a watcher, please check “How farming giant seaweed can feed fish and fix the climate.”
2. Looking for a career change? 3d ocean farming has been open-sourced!
If you’re looking for a career change, why not look at Bren Smith’s open-sourced business case for shellfish, oyster, and kelp farming below? You could earn money while doing your little bit to save the world!
3. Kelp farming could fix the oceans
Bren Smith has pioneered vertical kelp farming with shellfish at the bottom. It could feed the world *many* times over, easily feeding 10 or 11 billion people. It will also clean up our oceans, soak up excess nutrient flows from agriculture, soak up excess carbon dioxide from the oceans gradually removing ocean acidity, and stimulate fisheries and ocean ecosystems to grow. TED talk here.
4. Seaweed farming could fertilise farming
While kelp itself can be eaten in various salads and fried snacks and sushi, we can also harvest kelp for fertiliser for our cereal crops like corn, wheat, rice, etc. We could biochar it to improve soil quality. We can use kelp to recapture nutrients flushed out to sea and return NPK to our farms, creating a sustainable supply of non-mineral phosphorus! Kelp farming requires “no fresh water, no deforestation, and no fertilizer – all significant downsides to land-based farming – these ocean farms promise to be more sustainable than even the most environmentally-sensitive traditional farms.”
5. Seaweed farming could improve cattle gains
Some seaweeds can supplement cow diets to eliminate their methane burps! Cattle methane is not only bad for climate change, but can lose 15% of the cow’s potential growth!
6. Wave-powered ocean pumps can bring nutrients up to grow seaweed
The deeper parts of the oceans are nutrient ‘deserts’ where not much sealife can be supported. Nutrients fall to the bottom of the ocean, and plantkon and seaweed tend to grow where currents crash into continents, bringing nutrients upwelling to the surface. Dr Antoine De Ramon N’Yeurt proposes that wave-powered pumps could bring nutrients up to increase plankton growth, but the same technology could help seaweed. The video is about 10 years old but it could prove to be economically viable in so many different markets.
7. Ocean conservation groups to support
There are of course many marine conservation societies that you can support financially. I’m recommending 2 enormous organisations that are both friendly enough to the idea of nuclear power, and also work in most other areas of conservation as well. If you love their ocean work, chances are you’ll love their forest habitat protection, wetlands work, and many other areas of environmental protection.
The Nature Conservancy are open to nuclear power. Click this link to go to their page dedicated to the oceans.
Conservation International seem to allow nuclear power and have a beautiful page dedicated to the oceans.
Now to some other trends we might encourage that could have major effects not just on restoring the oceans, but feeding the world, restoring ocean acidity to normal levels, and even solving climate change and restoring atmospheric CO2 to normal levels by 2085!
8. It’s Sci-Fi now, but could it become a biological feedstock for vat grown beef to replace cattle?!
Now it gets crazy. We can turn kelp into meat! Vat-grown stem-cell meat is nearly economical. That is real meat, without hurting a single cow or chicken or pig or turkey. That would mean all the meat we could want, from the oceans! We use about a third of our land for grazing! Imagine handing that back to nature? Or there’s agroforestry with beautiful hardwoods for furniture? What about new parks as managed ecosystems for threatened species? Imagine being able to feed the world while healing the land?
