We have been trains from birth to be soulless consumers. That empty feeling we can not fill is our primal self trying to get out. We feed it endless things to try and make the feeling go away. If we where instead to just go out and create and play and enjoy the world, the feeling would vanish. But we have the programmed need to stick with our electronic toys and try to find happiness in them.
We have replaced mating ritual with the things we have. They are now what we show off instead of our brains or our brawn. This will attract a mate for a short time then they will soon fall out of love with us and move on to the next empty soul. When we find a mate for the right reasons, they tend to stay.
Is it a wonder that we are killing the planet? When people stamp green on a product we look at it like it's less than we need. We want out fast turnover of goods and buy into the market. We are doomed for our need to consume.
