The 21st century， compared with the past 100 years， will be acentury of change， if not uncertainty. While it is hard to predict whatthis new century will bring us， there are indications that advanceswill be made in certain areas. The following are two examples.
First， advances will continue to be made in the field of medicinethat will allow people to live longer and healthier lives.Steadyprogress has been made in the eradication of diseases and this shouldcontinue in the next 100 years. In addition， biotechnology in the fieldof genetics may someday allow us to develop bodies that are strongerand free of inherited defects. Second， as communication becomesmore efficient in the 21st century， this planet will become more like aglobal village. Peoples will have stronger bonds both economicallyand politically. Perhaps some day in the future there will be nonational boundaries.
The scenarios above are just two of the many possible changesthat this new century will bring. Although there may be problems inthe future， our ingenuity and inventiveness will help to deal withthem.
