Yes, we need to significantly reduce the amount of consumed meat (maybe not insects, if we consider them meat). A step towards more vegan and vegetarian food would definitely be necessary. Yes, not everyone needs to be vegan. But we need to consume way more vegan and vegetarian food.
There is a general consensus that insects are not considered equal in terms of animal cruelty like mammals, as they have much smaller and simpler nerve systems.
In regards to ecological imprint insects have a much better feed to food ratio and you can feed them much more things than to grazing animals.
In vegan communities insects are very much extended the same moral considerations as other animals. What you’re advocating is a form of speciesism, which is something better avoided as much as possible.
I’m not keen on eating bugs, most of them just are similar in environmental damage as vegan food. Insects are also already in almost all processed foods because they are small and almost everywhere. They just don’t fall in the same category as what we in the western civilization typically consider meat (as a food).
