A little reminder about how much society has done for us

Every once in a while I think it's good to find a way to remind myself how much humans are reliant upon our social evolution for survival. Forget living how we currently do, it'd take days or even weeks of work just to scrounge out the tools this guy used in making this little piece of bread, and even this super basic recipe took many lifetimes of learning to be created (makes you wonder how many people had to get sick to figure out how to remove the poison from yucca).

Anyway, it's all very humbling and makes me want to make sure that in my life time I can contribute some little smidgeon of something that will make people's lives more livable (in whatever form it may be).
