The 21st century has begun.What changes do you think this new century will bring?

The 21st century has begun, before it happens there were a lot of predictions about its coming. Some people predicted the end of the world and others predicted some changes and events.

I think this century will bring lots of changes in all the fields that are very important in our lives. They have a lot of effects on our lives in very different fields. There are both positive and negative aspects that would mention below.

First of all, in the near future computer controlled robots and machines may replace manual labor and the use of human efforts because of technology improvements. For instance,  we can expect a big change on transportation system.Cars and trains would be changed to the faster and automatic ones. They won't need any drivers and we may take a long distance just in some minutes. The c Computers will improve and they may work with our voice and do our orders without our interferences.

About the next case, the new century will bring some improvements in healthcare and medical science. There are some threatening diseases without any exact remedy like cancers and AIDS, so I expect new century to bring the good solutions for these kinds of illnesses. Moreover , I suppose, we will have lots of artificial parts of human body for replacing into patients ' body  bodies.

Finally, I hope the 21st century to bring some changes in education system like virtual and online schools and universities.
In spite of the fact that we will have a lot of improvements in the near future,there would be some difficulties like new diseases, growing population, lack of energy and fuel or gas. The world has some public problems that can affect our lives in every where such as global warming, air pollution, unknown diseases and catastrophe like earthquake, tsunami and flood. Thus, I hope new century to bring some exact solutions for these problems to save people's lives. For example prediction of earthquake and tsunami before happening is one of these solutions that people need in all over the world.

Taking into account of all these factors we may reach the conclusion that new century will definitely bring some changes in our lives with both positive and negative aspects. All of us have some predictions about future, but no one knows that what is exactly waiting for us in the near future.
