Water is a powerful substance and, indeed, where water is the boss the land obeys. The look and features of coastal areas are enough to give you this feel; wherever water reigns, the land is cut and shaped in a manner dictated by the water and the land loses control of itself completely.
Aside from coastal areas, even on the mainland, rivers and other water bodies influence the land profoundly. As they head down towards the sea, they cut deep into the land to create long-stretched valleys – their effect on the land cannot be overlooked. In all these, the land, by itself, can do nothing to undo what water had done.
In the same way, everyone is entitled to his territory. You cannot or should not go to someone’s jurisdiction and boss over him. All those who did that started conflicts. In times past, during the colonial era, the European countries who came to Africa, Asia, and the Americas had many conflicts with the locals because the locals would not just allow these European foreigners to boss over them on their own land.
People are so power drunk, proud, and arrogant to the extent that they think they can boss over everyone everywhere.
