Traditional education taught that human economic development progressed from hunting to stock farming and then to agriculture. However, the only real difference is that stock farming is an economic method of obtaining food by domesticating livestock, while agriculture involves domesticating plants. Therefore, this three-stage development theory is no longer accepted. Instead, the development of human civilization can be seen in the evolution of transportation. To understand the nature of how the world changes, we should observe the development of transportation. The increasing speed of movement is the main evidence that society is changing rapidly. - Joseph’s “just my thoughts”
Architecture has developed in response to the epidemic. The city was designed to mitigate the risk of outbreaks. However, its high population density renders it susceptible to epidemics. A potential solution to this issue involves the construction of a water supply and sewage system, which safeguards individuals from waterborne infectious diseases (e.g., cholera) by effectively separating and burying water and sewage underground. Nonetheless, the advent of vaccines has facilitated the existence of megacities with populations exceeding 10 million people. Indeed, microorganisms predominantly populate the Earth. - Joseph’s “just my thoughts”
