Prompt: People are optimistic about 21st century. Many people think it is a good opportunity to find positive change in future. How do you think of the optimism? What changes would you like to be made in the new century?

The first decade of the 21st century has witnessed a series of great changes made by human races. Thus, a great number of people firmly believe that we will keep up this upward trend, achieving incredible goals in the next 90 years. Ċ This is not groundless when we consider the fact that technology, the main driving force behind productivity, has been developing in a variety of fields, from medical care meeting people's basic demand to space exploration closely related to the achievement of human being's initial dream. This means people's potentials in different areas can be exploited to a larger extent. Therefore, it is not unrealistic to expect more powerful and productive innovations to be developed in future, tackling problems people are confronted with today. Ċ Also, people in the new era have opened up their minds to new things, instead of staying conservative and resisting changes. In fact, people focus more on how to follow the new trend and benefit from the changes eventually. In other words, they attempt to keep positive to changes, regarding them as valuable chances to succeed. Ċ On the other hand, some people may hold a pessimistic attitude to the emergence of positive changes. They argue that people in the modern society tend to seek fame and wealth, becoming increasingly cold and selfish, which would drive up a series of social problems, such as crime or loneliness. In such cases, it would be tough to achieve positive changes. Ċ Personally, I am still looking forward to positive changes in future when people can care more others and the whole society. To be more precise, I suppose the environmental problems would be eventually addressed with technological advances and more importance people have attached to the earth. Also, I expect scientists would explore more space on another planet for human beings to live in.
