As hunger rises resolutely up the global agenda in lockstep with global population growth, people will become less picky about where they get their nutrients from.
The supporting science will be provided by those who can see the need for the relevant skills, which will in turn provide a secure field of employment. (They might even earn enough to repay their tuition fees.)

Wrong solution to the overpopulation problem. Implement licence requirements for new births. Parents should be passing parenting exams and prove they can provide a decent education, decent food and living conditions before getting a birthing licence.

No, Mel; hunger does not rise with population. It rises with political turmoil. There is enough food and established technology to grow more, but various tariffs, embargoes, and outright war keeps the food from going where it's needed.
I'm glad Ms Clark mentioned insects use as poultry and fish feed. This step blocks many of the toxicities mentioned in the article and the health of the birds/fish serves as early warning for others. It also solves the "careful cleaning" dilemma and the "ick" factor.

Humm? You see this in The West, pressed before us by various sources with greater frequency. I recall one hilarious United Nations screed, that made me think of Johnathan Swift's satire, "A Modest Proposal" about eating the children of the poor to solve hunger issues. Yet the UN is serious, seriously a Leftest Socialist organization. Call it, "Top down, directorship/dictatorship of human beingthings." The "human" moniker might be dropped at a later date.
So will it really come to a "Bug de Jour" for the Saints of Western Civilization, the very civilization that people from the Third World jump into crowded boats to come to, like some kind of other Campy novel --French this time-- that comes to mind? NO, but we will see those who like to press, hammer squares into round holes, continue, as they continue on all sorts of other control issues. My hunch it is the same crowd that came up with Esperanto for a Global Language or those of the mindset that developed the famous resorts, called, "Gulags" in the former Soviet Union.
"Garcon! There is a bug in my soup!" "Oh! My apologies monsieur! That soup is for the table of Social Engineers over there." "Did they order a bug infested soup?" "Oh no monsieur, but our Chef insists that they have what they preach for."

Locust swarms could be a good thing.

You may disagree about eating insects due to your cultural upbringing, but ultimately I think it is the most efficient way to tackle the nutrition/resources problem.

The thought of eating insects bugs me.

With 6 billion mouths to feed on the planet Earth, and the numbers are constantly growing till we will have ten billion mouths to feed; what is a mother (Earth) to do? Food production in the industrialized nations is a trillion dollar industry, from cattle, to poultry, to grains and corn and feed, they are controlled by big agribusiness. In the US we produce so much food that the government buys up the surplus that is not sold, for there is a little known buy back program that places these surpluses in Federal Warehouses throughout the country; a billion dollar a year price tag that has refrigerated and non-refrigerated warehouses in ever major and minor city in the country. This federal program has been going on since the start of the Food stamp program; to assure that food prices would stay stable and that these business would stay profitable. Several billion pounds of food is stored in warehouses throughout the country, and is incinerated as it reaches it expiration date. We are told that insects would be a good source of food for the starving masses, but right now we have well feed rats that is (right now) living high on the surpluses food that are paid by tax dollars. Like the Irish famine that shipped large quantities of food from Ireland to pay off its national debt; so is the new "famine" a creation of man's greed. Whose cow is to be fattened; whose cow is to be slaughtered?

What most people don't realise or won't accept is the fact that with rising population available farming land keeps reducing. More and more farm area gets converted for housing and other amenities. It also puts heavy burden on resources. Strife is the result. Reducing the need would definitely be a better solution than to increase the supply.

One daughter, on a college trip to Ecuador was introduced to edible grubs. Unfortunately she had an allergic reaction. Our other daughter is working on her Nutrition degree and we tease her about adding a minor in entomology. Livestock feed and food additives will likely come first. Live bait vending machines are in use here in rural New York State so infrastructure in place.
