Many people are optimistic about the 21st century and regard it as an opportunity to make positive changes to the world. To what extent do you agree or disagree with their optimism? What changes would you like to see in the 21st century?


The first decade of the 21st century has witnessed a series of great changes that has never happened before. Thus, many people take an optimistic attitude that we will keep on this upward trend in the new millennium.

The optimism stem from the rapid development of science and technology. The medical advancements have cured millions of people who suffered from diseases that were considered fatal a hundred years ago. Communications can be made across countries without delay even from earth to the space. Travelling around the world used to take 80 days or even longer, while nowadays a tour guide may include sightseeing and shopping, lasting less than one month.

Nevertheless, negative impacts arise nevertheless the above advancement are such earthshaking. The balance of environmental protection and economic development is a dilemma for most countries and as a result our planet is greatly damaged. Greenhouse gases and global warming have caused holes in ozone layers already. The amount of catastrophes occurred in this decade is more than ever. Better living standards do not reduce the crime rates because of the widening gap between the rich and the poor. According to an authority survey, individuals’ sense of happiness is much lower than last century. People believe to achieve self-fulfilment is by wealth and fame hence they are accompanied by gruelling work at the day and loneliness lingered at night. Our eagerness to explore and pursuits to innovate doesn’t seem to make our life happier.

In conclusion, human race will achieve more accomplishment in the new century. Yet we cannot neglect the emergence of several problems with our environment, society and human beings. Those problems will only deteriorate until be solved which is unlikely to be achieved in the near future.
