As someone with an interest in Biology, and living in the same house since 1981 I have been watching the climate change for decades - plus I have read and heard about catastrophic population crashes when day length and temperatures become mismatches - so that, for instance, birds do not find foods for their chicks when they have hatched them. That includes such things as insect larvae and sand eels.
If locust swarms become common it would be a good idea to collect and process them as food for poultry, as chickens in particular are quite expensive to feed, if people are not keen on the idea of eating locust, chickens are highly enthusiastic.
