As we contemplate courtship, we might recall that it was on this date in 1958 that The Smurfs debuted as a comic strip in Spirou, the longest-running Belgian comics magazine. A colony of small, blue, humanoid creatures who live in mushroom-shaped houses in the forest, The Smurfs was created by the artist Peyo (the pen name of Pierre Culliford). From that humble beginning, the franchise has expanded into advertising, films, TV series, ice capades, music, video games, theme parks, and dolls.

In addition to being home to men with questionable decision-making skills, Florida also seems to have some issues with bizarre animal behavior, whether it’s freezing iguanas dropping from trees or alligators battling pythons in the Everglades. When it comes to those animals, however, Floridians can truly put the blame on non-natives. Neither pythons nor green iguanas made the Sunshine State their home until we brought them there as pets.

In fact, there are lots of problematic invasive species that have spread through the pet trade, from predatory fish that can drag themselves between bodies of water to a crayfish that clones itself to reproduce. Those high-profile cases lead to some obvious questions, like whether pets really are more likely to be invasive and, if so, why?

Two Swiss researchers, Jérôme Gippeta and Cleo Bertelsmeier have now attempted to answer these questions. And their conclusion is that yes, our pets are more likely to be problems.

To answer the question of whether pets really are problematic, the researchers generated some basic statistics for different groups of animals (mammals, birds, reptiles, amphibians, and fish). These included estimates of the total number of species, as well as the number of those that are classified as invasive and the number that are part of the pet trade.

If pets were no more or less likely to be invasive, you’d expect to see the invasive ones occupy similar fractions of both the pet trade and the total number of species in that group. But that’s not what we see in any of the groups. Invasive mammal species were present at five times the rate in the pet trade as they are in the wild around the globe. There was a similar result in birds; for amphibians, invasive species were eight times more common in the pet trade and about 10 times more common in fish.

Overall, invasive species were 7.4 times more likely to be kept as pets than you’d expect based on their frequency among vertebrate populations.

But cause and effect can be difficult to disentangle. Do we choose species that are more likely to be invasive as pets? Or have pets ended up with more opportunities to invade new environments because we transport them around the world?…

Spoiler alert: it’s the former… A new study finds the factors making them easier to keep also help them spread: “Unfortunately, we like pets that are likely to be invasive species.”

As we ponder proliferation, we might recall that it was on this date in 1964 that a different kind of “invader,” the Beatles, set a record: they became the first artists to hold all top 5 spots on the Billboard Hot 100 on the same week, on April 4, 1964. 
#1. Can’t Buy Me Love
#2. Twist and Shout
#3. She Loves You
#4. I Want to Hold Your Hand
#5. Please Please Me
More Beatles on the Charts that week: #31 – I Saw Her Standing There, #41 – From Me To You, #46 – Do You Want To Know a Secret, #58 – All My Loving, #65 – You Can’t Do That, #68 – Roll Over Beethoven, #79 – Thank You Girl

At the time, the best-selling piece of Beatles merchandise was the “I Love Ringo” button.

“Let food be thy medicine and medicine be thy food”*…

 

Beef

 

We are on the cusp of the deepest, fastest, most consequential disruption in food and agricultural production since the first domestication of plants and animals ten thousand years ago. This is primarily a protein disruption driven by economics. The cost of proteins will be five times cheaper by 2030 and 10 times cheaper by 2035 than existing animal proteins, before ultimately approaching the cost of sugar. They will also be superior in every key attribute – more nutritious, healthier, better tasting, and more convenient, with almost unimaginable variety. This means that, by 2030, modern food products will be higher quality and cost less than half as much to produce as the animal-derived products they replace.

The impact of this disruption on industrial animal farming will be profound. By 2030, the number of cows in the U.S. will have fallen by 50% and the cattle farming industry will be all but bankrupt. All other livestock industries will suffer a similar fate, while the knock-on effects for crop farmers and businesses throughout the value chain will be severe.

This is the result of rapid advances in precision biology that have allowed us to make huge strides in precision fermentation, a process that allows us to program microorganisms to produce almost any complex organic molecule.

These advances are now being combined with an entirely new model of production we call Food-as-Software, in which individual molecules engineered by scientists are uploaded to databases – molecular cookbooks that food engineers anywhere in the world can use to design products in the same way that software developers design apps. This model ensures constant iteration so that products improve rapidly, with each version superior and cheaper than the last. It also ensures a production system that is completely decentralized and much more stable and resilient than industrial animal agriculture, with fermentation farms located in or close to towns and cities.

This rapid improvement is in stark contrast to the industrial livestock production model, which has all but reached its limits in terms of scale, reach, and efficiency. As the most inefficient and economically vulnerable part of this system, cow products will be the first to feel the full force of modern food’s disruptive power. Modern alternatives will be up to 100 times more land efficient, 10-25 times more feedstock efficient, 20 times more time efficient, and 10 times more water efficient.1,2 They will also produce an order of magnitude less waste.

Modern foods have already started disrupting the ground meat market, but once cost parity is reached, we believe in 2021-23, adoption will tip and accelerate exponentially. The disruption will play out in a number of ways and does not rely solely on the direct, one-for-one substitution of end products. In some markets, only a small percentage of the ingredients need to be replaced for an entire product to be disrupted. The whole of the cow milk industry, for example, will start to collapse once modern food technologies have replaced the proteins in a bottle of milk – just 3.3% of its content. The industry, which is already balancing on a knife edge, will thus be all but bankrupt by 2030.

This is not, therefore, one disruption but many in parallel, with each overlapping, reinforcing, and accelerating one another. Product after product that we extract from the cow will be replaced by superior, cheaper, modern alternatives, triggering a death spiral of increasing prices, decreasing demand, and reversing economies of scale for the industrial cattle farming industry, which will collapse long before we see modern technologies produce the perfect, cellular steak…

As to what’s happening in the meantime…

• Undocumented ship-to-ship transfers funnel illegal, unreported, and unregulated fish to market. It’s probably worse than we thought: “Clandestine Fish Handoffs.”

• With a new California Cattle Council now in play, the state’s beef producers will up the ante in research and education: “California cattle producers beef up state’s cattle business” [source of the image above].

As we dig in, we might recall that it was on this date in 1964 that Teressa Bellissimo, at the Anchor Bar in Buffalo, New York, created Buffalo Hot Wings as a snack for her son and several of his college friends.  Her “invention”– an unbreaded chicken wing section (flat or drumette), generally deep-fried then coated or dipped in a sauce consisting of a vinegar-based cayenne pepper hot sauce and melted butter, and served with with celery and carrot sticks and with blue cheese dressing or ranch dressing for dipping– has become a barroom and fast food staple… and has inspired a plethora of “Buffalo” dishes (other fried foods with dipping sauces).

Aquariums are currently all the rage. Of the forty-one American aquariums accredited by the American Zoo and Aquarium Association in 2003, more than half opened since 1980, sixteen since 1990 alone.These are not traditional halls of fish tanks but huge, immersive environments with increasingly exotic fish in ever more realistic habitats: live coral reefs, artificial currents, indoor jungles, and living kelp forests. Massive public/private endeavors, the new breed of aquarium has flourished in an era of ambitious urban renewal aimed at reviving derelict inner-city waterfronts. Their prominent role in such schemes has caused the Wall Street Journal to dub the last two decades “the age of aquariums.” We are in love with looking at fish. But why?…

As we dive, dive, dive, we might recall that it was on this date in 1875 that the first sounding of the Mariana Trench– the deepest natural trench on Earth– was made by the British survey ship H.M.S. Challenger during its first global expedition.  Accurate measurements from the surface remain difficult; but in 2010, NOAA used sound pulses to record a 36,070-ft (10,994 m) depth in the Challenger Deep at the southern end of the Mariana.

The Challenger‘s voyage was the first expedition organized specifically to gather data on a wide range of ocean features, including ocean temperatures seawater chemistry, currents, marine life, and the geology of the seafloor– that’s to say, it was the birth of modern oceanography.

Hidden in a bend of the Mississippi River just south of New Orleans, 29 concrete bunkers lie on a grid of dirt and grass roads. Some hold remnants from the past—40-year-old gas masks and biohazard signs still hang on a wall. Most of them have been abandoned for decades. But inside two of those bunkers, 15 million fish eyes stare at the walls through the glass of their jars. This is the Royal D. Suttkus Fish Collection, the largest collection of preserved fish in the world, and almost no one knows it exists…

More of the story– and explore the collection– at “A Pair of WWII Bunkers in New Orleans Contains 7 Million Fish.”

As we ponder preservation, we might spare a thought for David Starr Jordan; he died on this date in 1931.  The leading ichthyologist of his time, he was also an educator and advocate for science.  He became the youngest President of Indiana University, then founding President of Stanford; he was an expert witness at the Scopes Trial, testifying for the efficacy of the theory of evolution.

His career was not unblemished however: he helped cover up the murder of Jane Stanford, and argued in favor of eugenics.
