I am in my fifties now and things in the human,animal and plant world haven't changed much since I was a kid. In the human world things seem to get better for a while, our technology gets better our knowledge of diseases and how to alleviate them gets better but then a new disease comes along or our primordial instincts kick in conflict arises and the subsequent flood of refugees fleeing war torn areas and religious extremism begins and everyone rushes out to help them. The same story keeps recycling itself over and over and it has since biblical times.
Just as in the plant and animal world some species thrive for a while because of their environment then die out when conditions change and others adapt and continue thriving and it seems we humans have the unique ability to adapt and not change but still thrive it's really amazing when you think about it,
