Human emotional tears are anti-fungal, thanks to salt, protein defensins and dermcidin. This developed as a result of living around seawater for millions of years, where both salt and water are abundant. The same is true of eccrine sweat.
Chimps, gorillas and orangutans left the mangrove rich seashores millions of years before, their rare tears and sweat are not saline, because there is almost no salt in the rainforest.
There is very little inland Iodine and Selenium (plentiful in the sea), so hypothyroidism, cretinism and goiters are often found in people living far from the sea, or on mountain islands without easy access to the lower shores.
Common chimps don't weep tears, rather they become enraged. (I hate you!)
Pygmy chimps also don't weep, rather they have sex play. (I distract you!)
Humans do weep, those that don't, are in a more primitive state of emotion; a stronger brittle shell but a more fragile center. Prisons are full of people who never weep. Psychiatric hospitals have people that can't release their emotions in a healthy way, so doctors medicate, but usually only dull the senses.
Tears release tension which otherwise destroys bonds.
"Tears : Tears produced by emotional crying differ in chemical content from those caused by irritants such as onion juice. Emotional tears contain more protein than tears induced by irritants. Researchers are now examining the contents of emotional tears for substances such as endorphins, ACTH, prolactin and growth hormone, all of which are released by stress. While the research on psychoactive substances in tears is just beginning, there is reason to think that emotional tears may be important in the maintenance of physical health and emotional balance.
Crying is not grief; it is a way of getting over your grief. Trembling isn't the same as fear. Rather it is part of a letting go of fear. In the same manner, embarrassed laughter, yawning, and even rapid, excited talking are parts of the healing process that get mistaken for symptoms of the problem".
Somebody must care about the forest, the field, the ocean, more than the individuals, otherwise the individuals overpopulate and destroy the environment ("tragedy of the commons").
But if nobody cares about that somebody, then it doesn't matter.
It just becomes numbers, and resource warfare, which just escalates, until people stop planting food crops, being too busy destroying and defending property and rituals. Then only wild forest food is easily obtained, but that soon disappears, leaving famine and chaos. This can happen anywhere there are humans.
