Insects. And you have issues with GM crops. Hmmmmmm...
Firstly, the econlogical issue is that insects are vital to maintaining the ecosystem as is. Removing them would have catastophic effects on it- flowers would not be polinated, plant and animal waste would not rot, etc, etc.
Secondly, a good many insects are highly toxic to human consumption. That is why we don't eat them, and why most cultures that do are ones that developed in a place where there is little food (Like deserts)
Thirdly, the main issue is that many countrys, in particular Africa, are having too many children, and too many of them are surviving. Thus, as in accordance with Malthusian population dynamics, the population rapidly outstrips the optimum for efficency and eventually, the food supply itself, resulting in famie, disease and war.
Fourthly: How doth one plan to farm insects? Ah, an issue.
I have an issue with GM crops because there have yet to be any conclusive evidence that show it is harmful or benign - just like mobile phones ( I also have issues with mobile phones, just like your typical neurosurgeon who avoids holding a mobile phones against his / her ear). There simply hasn't been enough time transpired for us to effectively gauge what long-term effects may arise, if any. Insects, on the other hand, are natural, just like the food you and I have ate since we were born, and before GM foods were introduced. Why would I have an issue with insects then? It's food, plain and simple. Animals - and humans - have eaten them since time immemorial.
First, insects are vital to the entire food chain, that is correct. I am not suggesting we go and pick them right out of their natural habitats. That would be both horribly inefficient and potentially devastating to the ecosystem. Sustainable farming, on the other hand, is a perfectly viable alternative, and is a practice we've been engaged in since we discovered agriculture and animal husbandry. Case in point: files are currently being sustainably bred today in 100% hygienic conditions in order to "harvest" the larvae that are hatched. The maggots are used in hospitals around the world, including the USA, for treating heavily-infected sores (since the maggots only eat the dead tissue while leaving the live tissue untouched, a perfect way to cleanse near-gangrenous wounds).
Second, nobody is suggesting that we eat toxic insects. In fact, why eat anything toxic at all? There are poisonous mushrooms but we don't tend to find them in supermarkets - at least, I hope not. We also know better than to eat poisonous mushrooms - why would we eat poisonous caterpillars, as an example? However, there are perfectly edible - and nutritious, and even delicious insects that are perfectly suitable for human consumption. And about desert regions tending to eat insects, I've had insects were in Colombia, Ecuador, Taiwan and Thailand. None of those countries are known for their deserts.
Your third point doesn't directly relate to insect consumption but to overpopulation and naturally regulating mechanisms as a whole, so I won't comment.
Fourth, it's not an issue at all. Like I said, I've eaten fried crickets and they are sourced from cricket farms, just like there are earthworm farms for live bait and fly / maggot farms for medical use. There are even ant farms that are sold to children as science projects. Insects are farmed all over the world for different purposes, including food.
