    Piranhas are one of those things I thought I’d need to worry about when I was young.ike quick sand and properly identifying if something is good or fool’s gold.

        acid rain was legit, then the world’s governments actually did something about it and it became not a thing. Much like the hole in the o-zone (at least until Elon’s vanity satellites start failing at a high enough rate to decimate the o-zone) and how we could mitigate climate change if there was political will

          Acid rain is real. So is quicksand. Either of them being common and severe hazards experienced across the entire US (and maybe elsewhere, I don’t know what the rest of you were taught in gradeschool), not really.

          Real acid rain causes mass ecological damage through relatively subtle increases in acidity over several exposures. The way we learned about it in school, whether they meant to or not, came across like concentrated hydrochloric acid was going to rain from the skies and melt human flesh on contact.

          The solution to acid rain actually made climate change worse. Well, not directly, just that it turns out that the sulphurs in the atmosphere that caused acid rain were also cooling the planet. With that gone, heat went up quite significantly, and research is being done now to see if we can put that back again much higher and in a more controlled way to regulate temperatures down a bit. We could add additions to airplane fuel, for example, that will disperse it throughout the atmosphere

    I can’t tell from the video if the water is just muddy or if it’s actually, y’know, gross. Is it safe to eat the fish from that river?

    Also, I’d always heard they didn’t do that unless they were starving. Which makes me think not much is surviving in that water, making me think it might not be safe to eat the fish :/

    Though, I imagine if you’re desperate for protein, such things are secondary concerns at best

      the issue today is thinking that mud is the definition of dirt, that river is probably 100 times cleaner than any tank/pond/lake used to farm fish, also i swan in pont that were way muddier, with piranhas too, sometimes

      Water can be like this when it rains a day or a couple hours before. Every river become like this when it rains. It is perfectly fine to eat fish from this river.

      Brazilian here. Perfectly safe (color-wise; of course it can be polluted as hell despite its color, just like any other river).

      Our ground/mud has a different color. Some areas on the south even have a red soil (very fertile, but makes everything about ground level look dirty very quickly): https://en.m.wikipedia.org/wiki/Red_soil

      There’s great variety of water colors even in the same area, just search for images “meeting of the waters Manaus”:

      confluence between the Black river of black water and the Solimões river of muddy water, where the waters of the two rivers run side by side without mixing

        Just jumping in to say that red soils are not very fertile. They are nutrient-poor in the necessary macro-nutrients (nitrogen, potassium, and phosphorus) and have a very poor ability to retain water. They are very rocky - little organic matter content - which limits both water retention and cationic exchange capacity (affecting N+ and K+ bioavailability), and tend to be acidic.

        Cultivation is possible, but it requires large amounts of fertilizers and soil conditioning agents (liming to raise pH and add calcium, addition of organic matter). In effect, recreating an artificial soil that is closer in nutrient availability to the black soils present in the world’s most fertile regions (which today are also heavily fertilized).

          • Put a piranha in the apple bobbing barrel for a “hardcore” mode.

          • April fools (self explanatory).

            1. That dude running with scissors has remarkable dexterity and aim to be able to quickly target thumbs, specifically. Its impressive.
            2. Did children not wonder why they never met anyone who was missing a thumb? Or was there some sort of bizarre plague in Germany at that time that caused many people to be missing thumbs?

              1. That dude running with scissors has remarkable dexterity and aim to be able to quickly target thumbs, specifically. Its impressive.

              It’s even more impressive as this seems to be his side-job or even hobby.

              This man is a professional tailor, but in his leisure time he storms like a SWAT team into family homes and his holy mission is to eradicate thumb-sucking everywhere.

              In my opinion the huge scissor means, that there are not only little thumb-suckers out there, but also proportional bigger ones and the tailor wants to be prepared for every one of them equally.

              So he aquired a special kind of skills in his career, handling the huge scissor.

              1. Did children not wonder why they never met anyone who was missing a thumb? Or was there some sort of bizarre plague in Germany at that time that caused many people to be missing thumbs?

              Would you ask questions as a kid if your parents are ok with invasion of privacy and involuntary amputation by some stranger and framing it normal?

        Reading more, everything I see describes them as bony, salty and very fishy tasting, best served smoked or grilled to mask the flavor.

                Yes, you can. Lettuce has around 2 gramm per 100. Apples 0.3

                As comparison beef has 26.

                So while lettuce has much less, saying you can’t get proteins from it is just plain wrong.

                  There are different kinds of proteins build from different amino acids, 9 of 20 amino acids are essential, meaning our bodies can not produce them, so we need to eat them. Meat contains all the amino acids we need in our bodies in the amount we need in our bodies. For vegetables that’s not necessarily the case.

                  Because of that vegetable protein needs to be very varied and balanced to be a complete diet, and just lettuce and apples is not enough.

                  In a first world country we can get these vegetable proteins varied and year round with little to no problem, which makes vegan diet a sustainable and morally superior diet.

                  In the developing world people are generally happy about being able to have a complete diet, moral questions take a backseat to survival and health, so carnivorous or piscivorous diets are far more common.

                  Pretty sure everyone else understood the meaning behind the sentence ‘you can get protein from lettuce and apples’. You need a certain amount of daily protein intake for a healthy diet and the comment implied you can get those from lettuce and apples. It is technically kinda true if you take it literally, but eating 5kg of lettuce is not practical.

                  Both lettuce and apples are incomplete sources of protein and could not sustain a healthy diet.

                  Fish is a complete source of protein.

      The one that I tasted was the red piranha, the same as in the video. The taste is… okay, not delectable but not awful; it’s simply a bit too strong. It goes great on soups/stews though.
