Food production is already well above what is needed to feed the entire population. The prodution volume is higher today than as ever been.
And if it wasn't for consecutive disastrous CAP agreements in the EU - and now I'm narrowing the scope - the overall food production in Europe alone would be much higher than it is today.
Narrowing the scope, in my country there is more land laid fallow and abandoned today than ever and growing each year, while modern culture techniques allow comparetively very small areas to produce more alone than huge areas in the past were ever able.
Live stock is also becoming more and more expensive to raise and the conditions to do so are becoming harder to achieve due to climate change. Traditional live small live stock live pidgeons, rabbits and other small and easy to keep animals have been pushed away in detriment of cows, again, in the EU, due to disastrous Common Agriculture Pacts, that actively subsidized cattle ranching in countries like Portugal and Spain, to allow France to produce cereals and other open field crops unrivaled.
But I can't agree the middle class is ballooning. Considering the current state of the global economy, it is in fact going through a hard pinch and shrinkage.
Recycling is not a red herring. The global production of plastics is a pain and largely a disaster to manage at end of chain but, again, because there is no guts for it. Every single small change to ban a specific single use plastic is met with great distrust, on the first line usually common citizens.
Unrecyclable plastics and other materials should be incinerated using pyrolitic combustion facilities for energy production instead of being buried in landfills. Recycling is already less expensive to do than extracting raw materials and it will keep developing. There is no other way.
I wholeheartedly agree things will get worse before they get better but I will insist it is not as bad as we are made to think and this is not in any degree denial of climate change nor any other problems.
