2 . Millions of people go online each day only for fun or to pass the time. Besides the list of things like books, music, movies and televisions, you can now add surfing the Internet as a primary way of entertainment and passing the time.
So how many people actually use the Internet today? According to some reports, about 40% of the world’s population has a connection with the Internet. That’s a huge increase from only 1% in 1995.
The number of Internet users continues to grow. In 2005, the number of Internet users was more than one billion. Just five years later, that number doubled to over two billion. In 2014 that number passed the three billion mark!
Today, about 75% of all Internet users live in the top 20 countries. The other 25% are spread out amongst the remaining countries. The country with the most Internet users is China with over 640 million users. The total is more than the next three countries—the United States, India and Japan—combined.
Of all those billions of Internet users, a large part of users are children. From computers in schools to mobile devices, children are growing up in a connected world. Studies have shown that over 75% of children spend more than two hours each day of “screen time”, which means time is spent in front of a computer or mobile device.
Too much “screen time” can be harmful to children. For example, too much screen time has been linked to many problems, such as high blood pressure, high cholesterol(胆固醇) and overweight. What’s more, school-age children who use a computer more than two hours per day are more likely to have emotional, social, and attention problems. Thus, if you’re one of the 75% that spend more than two hours per day in front of a screen, consider cutting back and getting outside to enjoy the natural world.
