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”
Even though a country's total population is decreasing, the economic situation could be improved by increasing the total economic activity of the remaining population after the decrease. Of course, there is a statistical population threshold below which this effect occurs. Nevertheless, this effect would not work in the case of a force majeure, such as a natural disaster or the outbreak of war, however, this assumption would be valid because a rapid population decline is a highly exceptional event that would not normally occur. Therefore, an increase in the economic activity of this population should be required during an economic recession. Applying this perspective, for building a solid relationship with your followers on Instagram, the number of followers is less important than the activity between them and you. This is called the "Engagement Rate (ER)". - Joseph’s “just my thoughts”
