In the 21st century, some things are the same as they’ve always been. For example, religion is as important in the lives of many people around the world as it has been for centuries.
But the world has also seen a lot of changes in how people live and work together. Sometimes, those changes bring big challenges. Technology, for example, lets people communicate faster and in new ways, but it has also given people fresh ways to take advantage of others.
Changes in one part of the world can affect other parts of the world. For example, some nations’ populations are growing, while the populations of others are shrinking. In general, however, the world’s population is growing. Estimates show that close to 10 billion people could be living on Earth by the year 2050. Experts say that could put a strain on resources, from food supplies to fuel reserves. The good news is that knowing these challenges are coming can help us prepare for and even avoid them.
