In this Our Changing Climate climate change video essay, I look at whether seaweed and kelp farming can save the planet and curb emissions like its promoters say seaweed does. Seaweed farming has existed for centuries but it only recently has come into the spotlight in the imperial core for its potential to grow food and animal feed as well as suck thousands of tons of carbon dioxide and emissions out of the air. Seaweed farming could be an essential tool in mitigating emissions and drawing down millions of tons of carbon dioxide from the atmosphere and back into the earth.

I think my main concern is that when 'big capital' gets wind of this, they'll try everything they can to farm as much as possible in as short a time as possible for the least amount of money as possible, very likely disregarding the environmental impact of the capitalist approach. My main hope for this industry is it helping to reduce methane production by cattle, cows in particular. And possibly enriching out diets :)

I recently moved to Maine and they've been farming kelp here for a while because the Gulf of Maine is warming faster than 90% of the rest of the world's oceans, and it's a possibility in a few decades, that the lobster fishing industry won't be sustainable anymore. so it's potential as a source of employment in a "post lobster" fishing Industry is welcome to say the least.

@@kaykay1570 at the risk of being baited, did you actually check the context? Specific kinds of seaweed can contribute to 80% less methane produced per cow. Methane is a far more potent greenhouse gas than CO2, if shorter lived. There are about 1 billion cows in the world. Now imagine their collective methane production reduced by 80%. Yes, there's still the landmass and water waste on cows alone, but for the short term, it's an amazing start if applied on a global scale.

I like it as a carbon sequestration tool as well as maybe a fertilizer bridge out of petroleum based fertilizer farming. If human waste isn't processed in a hydrothermal liquefaction power plant, it could be also processed in algae farms that utilize excess nutrients in human waste as well as farm manures, so catch those excess nutrients before they make it to the ocean, causing red tides and oxygen stealing blooms, and then keep those nutrients on land. It would just need to take care that it is not too salty at the end result, to not make the soil too salty. But I'm thinking something like a "soil bandaid knitting" factory would be very high in demand, not just a compost plant, but a fungi/mycelium garden that can create cover mats for barren soil or desertified prairies that are not naturally meant to be desert. It could be like (from bottom to top), a mat of: Wood ash] seaweed] Local invasive plants that have been boiled or composted hot] Local fungi to grow mycelium into the invasives] Farming waste such as hay, vegetable leaves like corn husks, And then top with tree leaf litter, fungi, and desalted-seaweed again. Then plant some cover crops on top that go with the local environment. I know it sounds ambitious and kind of over the top, but I think within 3 years and diligence, this seaweed and fungi assisted compost layering soil-knitting technique will help sequester carbon and revitalize soil.

Co2 sequestration requires draw-down to the ocean depths. Farming of seaweed/kelp alone does not remove the seaweed from the carbon cycle. Making products is great because it creates awareness and an economy, but it doesn't get it out of our atmosphere. When the carbon exists in the form of a plant, fertilizer, feed, etc, it will end up in the atmosphere again after decomposition. Growing it is key, but then we must sink it.

I hope in this way we could reduce demand for land-based farming (freeing up land to be converted back to natural sinks) and then imagine if all indoor farming units could be fed with organic, natural kelp fertilizer, which sucks huge amounts of CO2 out of the atmosphere. Would be a system with far less emissions possibly carbon negative, I believe the latest is that kelp can sequester up to 20 times more CO2 compared to an acre of forest? Plus it takes a new forest up to 100 years to reach their peak sink capacity

Lumber eventually decomposes into CO2; rich fertile soils are so because of fungal and bacterial activity, always in a state of decomposition and they also release - you guessed it - CO2. It might be a temporary storage, I agree with that. But unless we start burying organic material deep in the earth's crust, it's not a solution. Besides, vegetation (vegetalia) grows more easily and vigorously in CO2-rich ambients, so... 🤷‍♂️

Healthy ecosystems are mostly closed and balanced. Just on first principles it is doubtful that any resource can be harvested in industrial amounts without degrading the local environment over time.

great video but annoying transcripting. The sentences are all over the place and it's confusing to listen to something while reading a sentence that was supposed to be there, but was skipped or moved a few second later.

not to mention the missing words here and there. Kudos for the effort but please.

Isn't it more energy efficient and greener if people reduce eating meat?

Can we sustain Earth when our major economies are modeled for infinite, exponential growth? No. The logic doesn't add up. A cave person could do it.

Imagine if we ate 90% less meat, we could eat all that seaweed, as well as the corn meant for livestock right now. Eating meat as much as we do is so not needed. We could feed people with 80% of the food we give animals, from which we don’t get enough meat/milk/eggs to compensate that People are starving… If you don’t care about animals, care about people then, not just yourself. Also, mass agriculture is NEVER good, you’d think humans would have learned that by now ….

I agree with a lot of this video but the anti capitalist rhetoric is out of place. Capitalism is exactly why entrepreneurs are allowed to become seaweed farmers in the first place.
