When rain no longer is clean - then food no longer remains healthy. No matter how powerful the rainy season is. The vital point always is to have a clean pure rain irrigating the planet. If however the rain water itself no longer is drinking quality, then the food growing with that rain also no longer is edible quality!
To avoid a global disaster, mankind needs to learn to shrink its needs and requirements and learn as well to fully integrate into nature again. Mankind needs to learn to live with nature, from nature, serving nature as its main resource of healthy life.
I have never seen anyone eating household appliances or electronic gadgets. The profits or wages earned by working in industries finally always is needed to buy food. Hence instead of working FOR industries to gain money, lagter used to buy food, we could as well work again much more for farming and gardening to directly produce the natural, clean and healthy organic food we otherwise would have to buy with money earned in ill-making jobs in an ill-making and polluted industrial environment.
