What has changed the world since 1900?

The technological advancement in the past hundred years has led to radical changes in the lives of people. We talk about 'global village' and 'globalization' because faster communications and transportation have 'shrunk' the world. The death rate has come down considerably due to medical advancement and the population of the Earth has been increasing. The difference between the very poor and very rich countries is more pronounced.

How many people live in the world?

It is not easy to determine the exact number of people who live on the Earth since the number increases every second. Currently, there are more than six billion people on this planet. This is the number six followed by nine zeroes! Population grows in different countries at different rates. It is growing very rapidly in the third-world countries. The increase in population is putting considerable strain on the Earth's resources because more people always need more food and energy.

What is the 'global village'?

The term 'global village' is used to express the fact that distances between people have shortened and their ways of life are now more similar, just like in a village. Today, the same beverages are consumed on all the continents, the same cars are driven, and the same films are seen. However, many things are still unevenly distributed. In Europe there are many doctors, but there are only a few in Africa. Even clean drinking water and schools are taken for granted in some countries while others have to do without them.
