Milutin Milanković argued that the Earth’s Ice Age was caused by a change in the Earth’s orbit around the sun. This change is said to affect the inclination of the Earth’s northern and southern hemispheres and reduce the amount of solar radiation. However, the main reason is believed to be that summer isn’t hot enough. The ice kept accumulating as summer passed, and winter arrived before all the ice could melt. Even in our lives, things we neglect tend to build up and lead to big problems. Small, untreated chores can produce significant results over time. Good luck or bad luck, maybe that’s all there is. - Joseph’s “just my thoughts”
Before the high level of civilization, human life was tribal. However human beings were needed for the large-scale labor force for industrialization, so people were gathering in the cities for a living. That was the detribalization. These days when we are developed by social media, people are used to selectively make a relationship with those who have similar philosophies and preferences. Rather, the new media makes the retribalization in different meanings. Therefore, now human relationships are becoming more important the interests and preferences. When choosing to make a relationship, people gather according to their preferences. Communication is narrower and more easily ostracized. - Joseph’s “just my thoughts”
