Tofu never started a pandemic!
The potential is great but I think it’s better to rethink our current choices and be more conscious with the food that we now have. If we lessen our consumption of animal meat then we can focus on feeding supposed animal feed crops to humans. The use of land and water would be less alongside lower carbon emissions.
This is the way.
We have solutions, or at least ways we could drastically improve things, but I guess folks would rather accept that they’ll be left with algae patties in the future rather than working to limit their animal consumption today. I don’t get it.
Who said it has to be one or the other? We can pursue these new methods for tomorrow while simultaneously cutting down on animal products today.
These two things are not mutually exclusive.
I agree with you, and I never said they were mutually exclusive.
My comment was on how, in my admittedly limited experience, people see stories like this and seem to accept that they may have no choice but to eat stuff like this in the future while making no change to their current choices.
Yeah, I think there's a novelty factor in a lot of "innovations" that claim to be the secret to solving climate change. And while not inherently bad they sort of miss the picture in my opinion. Like, the future, in my opinion, should be made of trains and apartments. The dull things that we know work.
On a much more insidious level (not that I think anyone here has ill intent, nor the people working on these technologies) it almost implies that we don't have the technology to stop our impact on the climate. We have the technology, it's all political will.
Calling apartments "dull" is a bit generous
But animal meat is tasty 😣. Maybe plant based alternatives or lab grown meat will fill that gap and we can start using the farmland more efficiently
I get you and that’s why most environmentalists encourage people to go flexitarian instead of fully plant-based. Eating less animal products are no doubt better than doing nothing at all.
I committed to Veganism because it aligns with my personal ethics and so far, the mock meats have been doing great! Even when I was still living in a third world country outside US, I had access to delicious foods.
As lactose intolerant, I have been loving how many vegan products (mostly ice cream) have been appearing recently
Humans need some meat in their ration, and lab grown replacements etc are now too expensive for most of the planet.
However, "some" doesn't mean a burger or two every day, so yes, there's space for improvement. Meat is really expensive in terms of carbon emissions.
Frankly I'm not sure how one would notably reduce emissions of anything without actual control (like by force) over most of the world, where green stuff is less relevant than hunger and illiteracy.
But maybe it's best that USA and EU and similar developed countries don't have that control. I mean, green energy etc sometimes seem more important than actual lives being saved for many.
No, humans do not need meat. This is plain false! You can greatly decrease emissions by cutting out animal consumption and the FAO has been pleading for a global plant based diet for ages...

I already eat a lot of algae but the packaging always has warnings that algae are very high in iodine. You usually can only safely consume a gram or so per day. Strange that they didn't address this in the article...
This could be for marine algae, which might have high iodine and sometimes high organic arsenic (though there is some debate over how toxic that is) - but freshwater algae are not necessarily high in iodine. Like spirulina for example.
Seems to be species dependent. But it doesn't seem to be well studied. But the variation in iodine levels is crazy...

yep, these are all marine algae. I think the market will develop and more consistent products (and no doubt thorougly coated with preservatives) will become prevalent once dear old General Mills, ConAgra, and their like enter the fray.
I wonder if it's only some forms of algae, or if they can reduce iodine levels with processing and genetic modification.
Would we have to worry about mercury?
Unlike fish, Algae are basically the bottom of the food chain. Mercury is an issue because it bioaccumulates in higher trophic levels. Because Algae is right at the bottom, it won't collect very much at all.
The issue with marine algae is not mercury, but arsenic. We know inorganic arsenic is toxic, but marine algae accumulate arsenic in organic molecules, which some studies seem to show that is less toxic or even non-toxic. But some effects of arsenic toxicity are long term, like cancer, and apparently it is not a decided issue yet. There has been arsenic in the sea for a long time, and marine creatures of all sorts have evolved to deal with it in various ways.
Yes, seems to be species dependent. But it doesn't seem to be well studied. But the variation in iodine levels is crazy...

How do you eat it? I'm just learning about the world of eating algae now--outside of seaweed, that is (which I also just learned is algae and not just some underwater plant lol).
Well, I've been vegan for >11 years and love Korean & Japanese food that's why I eat it. Usually with rice, i.e. roasted seaweed like Nori leaves or already in stripes. Or as sushi. Also in soup like misoshiru where you usually have the stock from specific algae and you can even put wakame seaweed in it. With sushi you can often also get a wakame salad, which is really tasty, too.
But usually I just cook rice (or use leftovers) and mix it with sesame seeds, sesame oil, soy sauce and some form of seaweed (usually I get a seasoned package of roasted seaweed with added flavors, but nori leaves work great as well). All in all this is a great staple food because you can store everything for longer periods of time and it is easy to make.
Hope this helps!
I dont want to devolve into quoting like on reddit, but this article kept reminding me of the Simpsons.
"Thats what he was eating! Slime! And theres enough slime for all!"
This is interesting reading alongside the one from yesterday about blue carbon - in Aotearoa one of our fiord regions is looking at farming kelp in the same area, too!
After reading the article I'm thinking of trying to grow some. Anyone have experience with it and also on how it tastes? 😁
I watched some youtube videos about people growing spirulina in backyard pools. They tell all about how to do it. One guy says normally he would dry it to powder and add it to "regular" foods. But he sometimes just eats it as-collected. It has no taste, or sometimes a faintly "fishy" taste

Anyone here read Artemis by Andy Weir? Yeah...
I have it's a great book!
I feel like this kinda thing is a bit of a trope in sci-fi and cyberpunk, where one staple crop is used to cheaply feed a large number of people. In some works the staple crop is algae, in some it's soy, etc. Arguably, in the real world US it's corn.
I hope they taste great!
I'm sure we can bioengineer something that resembles fish taste with these 😃
Can't we do this in vertical farms, industrially, and not only take no more land from nature, but give land back. The more land we can return to nature the better.
From what I understand vertical farming really only works out economically for high value crops. Using artificial light instead of the sun takes a lot of energy, and tall buildings are expensive and require maintenance. Algae tanks would also be SUPER heavy, which is a whole other problem.
It's not ready, yet. But it could get started in places baking in too much solar.

Vertical farming is not sustainable with our current power options, we need every wh to replace fossil right now, we can’t add the energy needs of farming to the equation
It won't be tomorrow, but I think it will happen. It could start in regions baking in too much solar.
I’m always hoping fusion will do a major leap… I’ve been waiting for a while… but you’re right, there are niches, like places where nothing grows, where water is in short supply, etc.
Fusion is very hard. There's been some intriguing progress and I do believe we'll get there – and maybe sooner than many think – but to have a real effect on the climate change timeline I think we'd need to be just about finished with the experimental phase now (if not several years ago) and moving into widespread scale-up. That's just not realistic at this point, unfortunately. So while promising in the long view, I wouldn't bet on it solving any of our near-term problems.
(Edit: and that's ignoring the practical issues of sourcing the required amounts of deuterium / tritium and beryllium, which would rapidly exceed the entire world output under any kind of real scale-up)
Ugh don’t make me think about the tritium issue… I think we’ll get there too, but it should have been yesterday as you said…
Well at least we got voice controlled lights before the end of the world, that’s something… /s
Cool!
Wasn't Soylent Green algae based at first?
