My phone also screams (signals) when someone calls, must mean my phone feels pain I guess.
vegans apparently gonna have to eat air now
For me the question is if plants can actually hear these distress sounds, otherwise it’s not really for communication.
They probably do. But even if not, it can be used for communication with insects and other animals.
By contrast, stressed plants are much noisier, emitting an average up to around 40 clicks per hour depending on the species. And plants deprived of water have a noticeable sound profile. They start clicking more before they show visible signs of dehydrating, escalating as the plant grows more parched, before subsiding as the plant withers away.
someone smarter than me should get to inventing a device that listens to plant clicks and tells you when it needs water
That’s actually mentioned as one possible use case further down the article!
Might be a good use-case to have your home irrigation system be triggered by plant clicks instead of a schedule.
Well, sort of. Not in the same way you or I might scream. Rather, they emit popping or clicking noises in ultrasonic frequencies.
Another “science” community with clickbaity bullshit.
Eh… What? It’s an interesting article. The screaming is in quotation marks. So as far as I’m concerned, the title is fine.
Nah, the pops and clicks are just plant language for, “I give my consent to be your food. Namaste.”
I hear the screams of the vegetables (scream, scream, scream)
Watching their skins being peeled (having their insides revealed)
Grated and steamed with no mercy (burning off calories)
How do you think that feels? (bet it hurts really bad)
Carrot juice constitutes murder (V8’s genocide)
Greenhouses prisons for slaves (let my vegetables grow)
We have to stop all this gardening (it’s dirty as hell)
Let’s call a spade a spade (a spade is a spade is a spade is a spade is a…)
Salads are only for murders! Cole slaw’s a fascist regime!
Omg I had completely forgotten about this!
Hasn’t this study been done before? Feel like I’ve heard of grass “distress signals” from years back
Yes, remember that one as well, but this is a literal sound, not only a “plants communicate stress in some way” (if I remember the previous research correctly).
This sound right to me
I remember this mythbusters episode. They basically detected that plants “might “ scream or signal to other plants. They got some weird outliers too.
2/3 of crop calories go to humans
Source?
The paper is from 2013. The number of animals in factory farming were ramped up since then.
Then: She says crops not crop calories.
“From the 41 crops analyzed in this study, 9.46 × 1015 calories available in plant form are produced by crops globally, of which 55% directly feed humans. However, 36% of these produced calories go to animal feed, of which 89% is lost, such that only 4% of crop-produced calories are available to humans in the form of animal products. Another 9% of crop-produced calories are used for industrial uses and biofuels[…]”
55% + 9% = 64% = 2/3
So you’re correct with the 2/3 crop calories(!) if we count the 9% biofuel/industrial stuff with it.
But why is the following?
“According to a 2011 analysis, 75% of all agricultural land (including crop and pasture land) is dedicated to animal production.”
I’d suppose it’s because of this reasons: A. Pastures need a lot of space which for which often woods or rainforest are burned and biomes are destroyed. B. Probably the most eaten vegetable (potatoe) is very energy dense and has a lot less waste by-product and therefore needs a lot less space than animal feed like soy, wheat or corn.
This is everything I need to know from your paper to say that the system of animal agriculture is fucked, wasteful and destroys nature and our health (not only because of the pandemics it causes):
“Put another way, shifting the crops used for feed and other uses towards direct human food consumption could increase calories in the food system by 3.89 × 1015 calories, from 5.57 × 1015 to 9.46 × 1015 calories, or a ∼70% increase. A quadrillion (1 × 1015) food calories is enough to feed just over 1 billion people a 2700 calories per day diet for a year (which is 985 500 calories per year) [1]. Therefore, shifting the crop calories used for feed and other uses to direct human consumption could potentially feed an additional ∼4 billion people.”
Pastures can be regenerated, btw: https://www.reddit.com/r/farming/comments/1ds3fvh/how_to_turn_pasture_into_a_garden/
Edit: The latter is what the “Vegan Land Movement” is doing very successfully by rewilding pastures to wild lands again where a wide variety of wild life is finding a refugium now.
what I’m reading is that I’m right, and you would like to shift the discussion to land use
Nope. I’m not shifting anything. You were by changing the subject from crops to crop calories without taking into account humans can grow calorie dense foods on relatively small space opposed to animal feed which needs a lot crops, land and produces a lot of plant waste and in addition is inefficient because only a fraction of calories come out of the slaughtered being compared to the initial calories in plants.
All that while we cull millions of feeling beings in the worst possible way right now because of H5N1 (add that to the polycrisis) waste enormous amounts of resources for little protein and calories and destroy nature.

your dunk-brained links to Reddit are not getting clicked
the same crops that feed animals feed people. they eat fodder and industrial waste from the same fields that produce food that people eat. it’s a conservation of resources.
how do you measure crops if not by crop calories?
