Survival is a dominant part of the human experience. In less technological countries, survival requires getting food and shelter and avoiding harm from individual and governmental criminals. In more technological societies, the food and living space are in excess, but survival requires individuals and families to fit in the societal structure and follow the rules. Other dangers in technological societies include technological dangers and crime. The level of crime in technological countries is extremely high at any level, including governmental and international.
Our industry and shortsighted technology pollute the planet and this pollution leads to health problems everywhere, shortening life. Psychological stress and disease are the main causes of death in technological society at this time.
There is much contrast on our planet. There is a high level of duality. Moreover, we have not only good and bad extremes, not only black and white but also all colors in between. These extremes on Earth constantly produce variety.
The difficulty of survival on our planet also helps us to become very creative in problem-solving. When we join the galactic community this skill may be very useful to our galactic friends. (Speaking of the "galactic community", this term is outdated. I neither limit the potential for our contacts to Milky Way Galaxy nor our dimension.)
