    The John McPhee article that the author references was expanded into a book, and it's a great read for anyone that finds this story interesting: https://www.amazon.com/Oranges-John-McPhee-ebook/dp/B005E8AN...

      John McPhee is a great underrated non-fiction author, up there with the late Tracy Kidder. I particularly like McPhee's "The Curve of Binding Energy" about the physicist Theodore B. Taylor.

        This reminds me of the collapse of the Gros Michel banana variety, also due to disease. Near-100% loss of a food crop, even a luxury one, is an alarming thing to see though.

        (I was wondering if climate change would be mentioned, but that doesn't seem to be critical there yet. Starting to be noticed in European grape terroir.)

        • HugoTea 18 hours ago

          They mention it as a critical factor, the disease is spread by insects, which is spread by hurricanes. The areas they grow the oranges never used to get hurricanes.

          > Hurricanes turned out to be a vector for spreading the little winged bug. The wind carried the psyllid all over the state, dropping it off in hundreds of thousands of acres of groves.

          > It was the perfect storm. And then, of course, there were the actual perfect storms, the high-caliber hurricanes that, before climate change, didn’t come to the Ridge: Irma, Ian, Milton, massive cells, all direct hits on the groves.

            >The areas they grow the oranges never used to get hurricanes.

            That's not correct: we have good data going back to 1851:

            https://www.aoml.noaa.gov/hrd/hurdat/All_U.S._Hurricanes.htm...

            Search for "FL": hurricanes have been hitting Florida frequently for the last 175 years.

            • acdha an hour ago

              That's not the point being made: the article clearly states that those areas did not previously get hit by storms at this level. Climate change is making hurricanes stronger and wetter, so even though they've been a phenomenon for as long as humans have lived there that doesn't mean that the frequency of damaging storms over an area can't change in a way which makes it worse for agriculture. There's an inflation-adjusted list of weather events which caused the equivalent of a billion dollars or more in damages, and the upward trend is pretty clear — it's like dismissing the impact of the machine gun because people used to have long rifles.

              https://www.ncei.noaa.gov/access/billions/state-summary/FL

              You get a similar problem with saltwater intrusion where, yes, it's never not been a phenomenon but now it's affecting a lot more people than it used to:

                Hurricanes do more dollars in damage because we're richer and there's more capital near the coast.

                The idea that climate change caused hurricanes which spread insects is not impossible but seems unlikely. I don't think the statistical methods exist to prove it.

                Did this banana have seeds!? I've never seen one, but it looks awful. They were actually good?

                • xenadu02 27 minutes ago

                  Most edible bananas are seedless and most cultivars (human grown) bananas are genetic mutants with triploid chromosomes (though a few are tetrapolid or diploid). Getting them to produce functional reproductive structures at all let alone viable seeds is very difficult. There are ongoing efforts to cross-breed with their wild cousins and to preserve genetic diversity.

                  • advisedwang 4 hours ago

                    No, it didn't have seeds either.

                    Have you ever had "banana flavor" candy that doesn't really taste like bananas? The flavoring is Isoamyl acetate, and I've heard suggestion that people called it banana flavor because it tasted more like Gros Michel. After switching to Cavendish banana the flavor name no longer made as much sense. Not sure how true it is though.

                    • mech422 7 hours ago

                      I never had one, but apperently they tasted much better then the current variety (which IIRC, is in danger of suffering the same fate)

                      IIRC, there was actually a huge marketing push because people wouldn't each the current variety ?

                      PS - the old one didn't go 100% extinct, and you can get small numbers of them from specialty growers. Youtube has videos of people trying them (1)

                        I just want to proudly, but also sadly, boast that Polk county once produced more oranges than the entire state of California.

                        Florida was a beautiful place not long ago, but a very peculiar and aggressively anti indigenous development is redefining it daily. Things have become so strange that squalid retention ponds qualify as wetland restoration.

                        I could rant for a while, but won't. Sarasota once produced more celery than possibly all states combined, and that helped us get through the Depression locally. But we sure did grow some oranges, and how wonderful the scent of orange blossoms are. It's something to behold.

                          Meta: giving oranges as gifts at Christmas was a bit of a thing in the past when they used to be much more rare during winter: from Valencia/Ivrea for Europeans, and California/Florida in the US.

                          In the US the Interstate system helped reduce shipping and logistic costs across state lines, and so oranges became more prevalent and less 'special' post-WW2.

                              I'm also curious whether the bugs would survive if you cut down every orange tree in Florida, waited a couple of years, and then planted new groves.

                                Of note from the story: "...because it came from China, where oranges also came from in the first place." Technically yes but also no, what we have for the modern navel orange came from a mutation that happened in Brazil in the 1800s - 200 years after its introduction from China. The parent trees for literally the entire navel orange (aka Florida aka Sunkist orange) industry are in Riverside, CA, I see them every day driving to work. The now-deceased Queen of England used to get two boxes of oranges from those very trees every year.

                                  Makes the disease even more confounding, as one would assume that orange trees evolved alongside it. Normally invasives are destructive because the species has never seen it before.

                                        IIRC for sugar it's because of cheaper cane sugar substitutes (corn syrup and sugar beets) out-competing the cane sugar grown in Hawaii.

                                          Sugarcane was due to cheaper sources. Pineapples I think was due to economic factors as well. Basically, one of the most isolated population centers in the world adds a lot of cost due to shipping things in and out and being a US state imposes means that labor isn't going to be dirt cheap.

                                              The other thing that I can't help but think has seriously hurt the industry is that, between concentrate and flavor packs, almost all supermarket orange juice tastes like garbage. Fresh-squeezed orange juice is, of course, the benchmark. If you ever taste Minute Maid back-to-back with fresh-squeezed, well, you probably won't be buying Minute Maid again any time soon. It just doesn't even taste like oranges. There are a few brands available (the expensive ones, of course) that do come close enough to actually taste like oranges, but when the mass-market product falls that far down in quality, you can't help but wonder how anyone still wants to buy it.

                                                The process to make never concentrated orange juice logistically viable involves removing all the oxygen from the juice so it stores well. Now you can take a seasonal product like oranges and sell the juice the entire year around. Unfortunately removing the oxygen also removes most of the flavor. so what the bottlers do is add an engineered "flavor package" when they bottle the juice to add the flavor back.

                                                I am halfway convinced that flavor wise frozen concentrated orange juice is "closer to the tree" than the "never concentrated" stuff. Nothing on fresh squeezed. But that is the price we pay to have a non-seasonal product.

                                                  A local grocery store used to make their own fresh squeezed using a refrigerator sized stainless steel machine that might as well have been a Rube Goldberg machine with its winding metal wire chute full of oranges which led to the squeezing head. That thing was kept right in the aisle next to the refrigerator case they kept the juice in. It was the best orange juice though expensive as it was over 10 bucks a quart when the store finally closed. I tried to call and buy the machine but got nowhere. Turns out the owner died so the family closed up the shop and liquidated it.

                                                  As for Minute Maid, it has always tasted awful to me and it tasted worse in the 80s. The only packaged OJ I can stand is Tropicana.

The weird milky vaguely-citrus flavor of chemical that comes in the box labeled "Orange Juice" is just one of many examples. For another example, go taste a grape and then taste some so-called "grape juice." It's actually mostly apple juice, and doesn't even remotely taste like grapes.

                                                          • colechristensen 7 hours ago

                                                            Dark grape juice is made of concord grapes which are the primary variety which is made into jelly, jam, juice, and in general grape flavored things. They don't taste like grocery store eating grapes, they're a different variety.

                                                            THEY ARE DELICIOUS when you can find them, one of the things I miss about living in California was the brief season you could get a concord grape on the vine to eat. I have never seen them outside a bay area farmer's market, late summer if I remember correctly.

                                                              I love concord grapes so much. Im eagerly awaiting their annual return to the farmers market (early September). I love them so much the vendors know to get me and tell me when they are here. I don't understand why the demand for them is small.

                                                                I also deeply miss the limes. The halfway-to-yellow actually ripened limes that didn't even show up some years.

                                                                If I knew for sure when they would be available I'd certainly make a trip across the country to eat those limes.

You knew it was bad for you but it was so good that you just didn’t care and it was a great cheat meal. You could get an Angus Delux meal for $7. https://wealthgang.com/mcdonalds-prices-throughout-the-years...

                                                                      Of course they discontinued the angus burgers that actually used high quality ingredients compared to the McDouble / quarter pounders.

                                                                      Now it’s $12 for a double quarter pounder meal and it tastes like shit. I only notice this because I just didn’t eat there much in the last 15 years. Meat quality and bun quality has clearly gotten worse. I don’t know how they keep growing sales.

                                                                      • kevin_thibedeau an hour ago

                                                                      • baron816 8 hours ago

Then I found out that it was just all sugar and not much else. I don’t think I’ve had a glass of the stuff in over a decade.

It’s the act of having your guts extract the nutrients that makes fruit healthy, because it reduces how quickly your body absorbs it. Once you make it into juice (or a smoothie) by mechanically digesting it prior to consumption, you’ve removed the need for that.

Further research is needed to evaluate the potential effect of different artificial sweeteners and their doses on health.

I mean shoot, Aspartame immediately breaks down into some of the most common amino acids in the body. There's no biological mechanism for it to do anything negative.

                                                                                            Sugar, on the other hand, has very well known and studied health risks at the concentrations we see in a lot of modern 'staples' - soda and juice included.

Monoculture is often blamed, but the bacteria affects all citrus trees - oranges, limes, lemons, grapefruits, pomelos, etc.

                                                                                                      In the past, "monoculture" was used to describe things like "one particular variety of banana"[0] - e.g. the Gros Michel banana fell to fungus and was replaced by the Cavendish banana, which was not susceptible to the same fungus but is now also falling to a similar fungus, and will be replaced by another banana variety. In fact, they're not just the same species but closely related cultivars - both part of the AAA banana cultivar group (triploid cultivars of Musa acuminata).

                                                                                                      The article in Time Magazine puts it succinctly:

                                                                                                      > There’s a name for this situation: monoculture, the practice of fostering just one variety of something.

                                                                                                      In the case of bananas (and many other crops, plants, decorative trees, etc), a diversity of varieties would have minimized the spread and impact of pathogens, while providing a more diverse selection of nutritional content and flavor for consumers. But that doesn't seem to be the case for citrus trees.

                                                                                                      I don't think that "monoculture", as it has been used or the past 50+ years, is the appropriate concept to apply to this citrus greening. Perhaps we could criticize something else - like tree density? Or perhaps monoculture is the problem, but in a much broader sense - maybe a grove with 10% citrus trees, 10% corn, 10% soybeans, 10% berries, 10% apple trees, etc...would create a biome that was hostile to the citrus greening bacteria in such a way that it couldn't thrive and spread. We have no data to support that hypothesis at this time though.
