From when I started commenting on the Guardian about about 16 years ago, and more recently on Twitter/X I have been trying to get across that the climate and ecological crisis is likely to impact our societies with food shortages. That this is the mechanism most likely to cause collapse. Looking at it as an ecologist, I am used to looking at what is most likely to cause a collapse or decline in a species population. The limiting factor. Often it is food, but also water, temperature minimums or maximums, competition etc. Human society is slightly different, because we buy our food, technologies are used to increase food supply. So the mechanisms are a bit different, but broadly similar. Human societies are very vulnerable to food and water shortages, which can disrupt every aspect of this society, very rapidly. Unfortunately, economists who seem to determine government policy, don't think like this and are not familiar with ecological concepts. Even in the most advanced human societies, if food shortages lead to food hyperinflation, meaning a considerable proportion of the population struggles to by able to afford food, even if only temporarily. It could cause societal chaos, riots, and lead to a total lack of trust in government. Our countries could become ungovernable. This would affect every aspect of our economy, governance and financial system, and rapidly create a crisis. It is not me saying this. Well I am and having been saying it, but so have many other experts. The frightening thing, is that the silence from the government about the current climate emergency, indicates that the UK governments, and other governments have got no strategy for dealing with this. I am really struggling to cope with this, because I am not trying to promote myself as any sort of expert on this, but I don't know of anyone else who has a better handle on the nature of this crisis. Please note, I say "better". I am not saying no one else has a handle on this. Just that it doesn't seem better, they don't seem to have thought of many of the aspects I have. It would really make me feel a lot more secure, if there were other experts I could refer you to, but I don't know of any. xitter.cf/nebriefing/status/2001…
