Can seaweed help curb global warming? | Tim Flannery

[@invox9490]

I've learned somewhere that in days of early civilization, humans used seaweed to fertilize fields... Maybe that could be a thing.

[@forbaldo1]

it never stopped the computers in your hands use it go to bunnings🤪

[@infdawg]

It's still a thing in a lot of coastal areas. I've done it myself. It's a very effective fertilizer.

[@alpaykasal2902]

Seaweed is great as fertilizer, but that process does not remove the co2 seaweed embodies from the atmosphere. The goal of this talk is to remove the co2 completely and lock it up at depth.

[@yoavsnake]

The US subsidizes huge amounts of crop such as wheat and corn, which has also created artificial demand (Sugar epidemic, Bread in the food pyramid for example). Maybe they can transition slowly into seaweed subsidies too.

No wasted words here. EVERY single word adds up to good sense.

[@lichenporifera8784]

The mass production of seaweed can be paired with sea sponges. Sea sponges help keep the seaweed healthy by filtering the water of bacteria and pollutants. Later on it can be used to produce sand. (There is a huge global shortage of sand)

[@robsonneves6189]

Great presentation, reminds me of one of my favorites that is a talk about how we could easily feed the world population with these underwater ocean farms. Lines up perfectly with this one, so not only famine wouldn't be a problem but climate change too, what a great idea.

[@j.s1805]

hurry up and get them farms going i want all you can eat seaweed salads!!!!

[@erikkalkoken3494]

That would be counter-productive. If people eat it most of the carbon would go back into the atmosphere. The whole point of this idea is to bury the sea weed into the deep oceans.

[@unbreakableldorado7723]

This deserves way more attention

[@StudioSkiesAndWater]

I heard if you don't eat animals, it is the easiest thing we can do right now, and most significant

[@FranciscoSciaraffia]

if i had any saying in this i would switch to hydroponic interior farming and lab grown meat. that alone would allows us to return 90% of the land we currently use for farming and cattle and turn them back into forests. we currently use 40% of the earth as farm land... that 90% would make a huge difference.

[@MrBarryyoung]

Unfortunately those two solutions have their own problems. While hydroponics reduce the amount of land and water over traditional farming. It requires a ton more energy and huge start-up costs. We also would have to convert traditional land to hydroponic farms, since urban/suburban land is too expensive. If you are looking to do multiple story farms its way too expensive due to construction and lighting. Right now there are only a few crops that justify growing hydroponically. Lab grow meat will also be very expensive. This is mostly due to the media it is grown on, the most popular is FBS (fetal bovine serum, literally unborn calf blood taken from slaughtered pregnant cows). While I applaud the efforts going into this I am not sure it will ever be economically viable. The simplest and easiest method (from an agricultural perspective) is veganism. And while I am not a vegan, nor a vegetarian; I do try my best to lower my animal based food intake. I wish money wasn't the driving factor in business, but unfortunately if you cannot justify things financially it is hard for a business to take on the endeavor.

[@petritamallorca]

Enhancing a natural process! That’s it! 🤷‍♀️👍🏻

[@m4r7ijn]

Awesome theory! The seas definitely hold a large part of the answer to climate change. Yet, 9% is unbelievably gigantic, it would already be amazing if 0.09% could work as a technical challenge. Like anything related to climate change there is not going to be one single solution. Instead, it will be a collaboration of leading scientific entrepreneurs such as this guy., each with his or her own part of the solution. Let's focus on giving space to such innovations!

[@lauredewinter5860]

9% is indeed a considerable amount of surface but over time and with the right investments, I think we could achieve this. Even though a lot of opportunities are thrown away when it comes to solving climate change, with enough media attention, a lot could be changed. It would probably take at least a decade to make people aware of how critical our situation is and that we need to intervene and it is why TED talks like these are important.

[@morphers21]

This is indirect c02 capture right because the seaweed pulls the c02 from the ocean water and not from the air.

[@jchampagne2]

This could be a really huge idea, like analogous to humans going from hunter-gatherers to farmers. If you could put even a fraction of the world's roughly 30 million career capture fishers to work as marine permaculture farmers it would give them job security (and for many, relative on-the-job safety), it would help with carbon drawdown, and would probably be more productive for the input of effort to output of marine protein into the supply chain.

[@thelivingclassroom7205]

Great presentation! We could combine Oceanic Permaculture with Onshore Permaculture to store the carbon back in our soils!

Very competent and promising talk. But given the state of the world today, the project will not get of the ground unless someone can make money out of it.

[@SystemLordNemo]

Indeed. I'm loss why so many do not understand this. Personally I would genetically engineer good tasting seaweed to make a great product, make tons of money, feed the world and solve climate problem.

[@elahn_i]

Money can be made from it, simply by selling the seafood at market rates. The problem is the investment finance model, which demands a high rate of profit for anything commercially unproven.

[@myates4652]

I agree, but it still can be a profitable endeavor. Seaweed for human or animal consumption, protein production off the same source. Remember there will be inedible or discarded parts of the production that could be released in the way he speaks, but the initial startup costs are the true hurdle.

[@nil981]

Remember folks....if TEDX is promoting it, it's not legitimate.

@FOUR Strokes! What would be his reason to go on stage and lie about this? It serves him no financial benefits or other benefits.

[@thepeff]

This dude isn’t talking about what he’s DOING to change the planet. He’s just got a plan that’s as thin as the napkins he does his calculations on. If this was someone who is part of the kelp industry this talk would be informative instead of speculative.

[@nurdianasri8292]

Maybe in the near future, someone will realize and founfd a way, to utilize the seaweed into animal feed. The animal then lock up the CO2 long term, convert that CO2 into protein that we are all can enjoy as nowadays meal.

after a bit more reading, looks like the seaweed will have to be buried in the sediment of the ocean floor. No small feat but hey, it's got to be more feasible and cheaper than a lot of other carbon capture methods at the moment. And it can be scaled-up, lotsa room out there
