The predictions about life in 2050

People and the Internet

In 2050, everyone in the world will have a personal web page with their information on it. These web pages will use the five senses: sight, touch, smell, taste and hearing. This way, before you meet someone, you can check out his or her web page to learn about the person.

People and the Environment

In 2050, there won’t be enough water for the world’s population. Because of the changes in climate and increase in farming, some places will be drier and people will not be able to produce enough food. The demand for water will create problems between countries and these problems may lead to war.

World Population

By 2050, the population of the world will come to the highest point, probably around 8.5 billion people, and then it will start to decline. The structure of the population will also change. Most people will be over 60 years old.
