Many people don't have air conditioners (they tend to be useful only a few days a year so most people don't invest in them, especially the poor).
Indeed, and for the poor who have to walk or bike everywhere, air conditioning aids to help with non acclimation, so movement outdoors becomes even more unbearable for poor folks who decide to invest in AC anyway.
I've been without AC my entire adult life and it's usually a fleeting thought once in a while that "AC sure would be nice today", but maybe I will live longer as a result of not having it :D
I remember Death Valley holds the record I think, and the hottest place I've ever been was not terribly far from there, 29 Palms California. I do not miss that kind of heat.
The photo's are very nice, and I'm confident you will find a way to maximize your yields regardless of the challenges you are currently facing with this heat wave. Thanks for sharing.
