Many cities are changing their New Year's Eve parties. This year, celebrations are smaller. Some cities have cancelled big events. Paris, Tokyo, and Belgrade will not have their usual large parties. This is because of security worries. These worries have grown over the last ten years.
Past attacks have happened during public celebrations. For example, there was an attack at a Christmas market. Also, cars have hit crowds. A bombing happened in Nashville on Christmas. These events show that violence can happen at happy times. Authorities find it hard to keep large crowds safe.
New York City will still have its famous ball drop. However, there will be many security guards. The city has planned for months to make it safe. Security is now very important for big events. People are also changing how they celebrate. Travel agents say more people want private parties. They prefer smaller events over large public ones. People want to feel safe.
The world is celebrating the new year differently. It is a mix of fun and safety rules. Past events have taught us to be careful. Smaller celebrations show that security is a big concern. People want to celebrate, but they also want to be safe.
