In this paper I will talk about the topic that technology will eventually destroy the entire civilization, since people are greedy and the revenge of nature. After reading Spiritwalker, the first thought that came to my mind was whether or not humans will be destroyed by technology. Different people have different answers. Technology's advantages and disadvantages are a subject of constant discussion. Those who are against technology have the opinion that technology harms people and will ultimately ruin human civilization. Threats to the environment are pollution, resource depletion, greenhouse gas, and nuclear power abuse. Those who find technology advantageous, on the other hand, argue that technology benefits people. For example, the internet facilitates the communication between the diversity groups of people. Genetics increase people's lives and cure diseases, and the invention of the airplane reduces the time of traveling from one side of the world to another one.
The main line of the story is through the main character, "I", entering Nainoa's (a future character who lives 5,000 years from now) body to experience his void of technology. The story begins in August of 1983. It is the first time that the main character entered Nainoa's body. During his strange journey, the main character could share Nainoa's feelings, observe the future world, and even read Nainoa's mind. The future world is very strange because the future looks like an aboriginal society of the past. People have reverted back to the use of wood and stone as tools and weapons. They also use cotton and fiber to make clothes and do not have transportation tools. I am astounded by this unbelievable situation that looks like our ancestors' life in a horrible and harsh environment. People can be eaten by animals. Without hospitals and medicine, people easily die from disease. How can human history regress to the way it was thousands of years ago? There are three main tribes in the future. Each of them is dependent on natural resources. One focuses on agriculture, one lives by invading others and another lives by hunting animals. Where has the modern civilization gone? Why does the future of human look like the Stone Age? Does it mean that our society is declining instead of progressing? In order to defend against another tribe's attack, Nainoa is sent over the mountains to find horses. He travels a very long time to look for the lost western civilization.
