Humans are adaptable creatures. When change happens gradually, each succeeding generation accepts the way things are as the new normal. It's the old who suffer the most because they remember "The good old days". For instance, Tolkien wrote Lord of the Rings mostly out of nostalgia for a pastoral England that he felt had been lost to industrialization. That kind of nostalgia was way before my time but I'm old enough to register negative changes of my own, like the gentrification in my suburban hometown and how the world feels increasingly crowded, polluted, noisy. Products are flimsier. People are trashier, ruder, etc...
Point being that as implausible as it may be to eat bugs today, it may come time when it becomes the new normal, and even soylent green (where people know where it comes from). All this because change happens gradually and because as each generation comes of age, they can't mourn what they never personally experienced.
If you actually look at the broad tapestry, there's one and only one universal constant, which is overpopulation. Due to the change in the forum, it might not be welcome to suggest that the population of the world is unsustainable, but articles like this are canaries in the coal mine. Journalists these days feel they operate on behalf of the public good, like quasi-activists. So they are going to seek out stories that they think illustrate how we might get by if the population keeps doubling, because you're not going to feed such a population on grass-fed beef and free-range chicken, that's for damn sure. Infinite growth on a finite planet is impossible. You can pretend it is all you like but eventually you'll look around and see how much of a cesspool the planet has become and won't be able to blame it on anything (or anybody) else anymore.
