Fifty years ago, the tools we rely upon to communicate today were only science fiction. Today, you can purchase a smartphone and make calls, surf the Web, play games, run applications and accomplish more than most speculative fiction authors dared to dream. So what's next?
In the short term, we'll likely see basic cell phones slowly fade away. As smartphones become more common and less expensive, more people will adopt them. The process is gradual. As with most new technologies, a group of enthusiastic adopters lead the way. Sometimes, the general population will follow the early pioneers -- the compact disc is a good example of such technology. In other cases, the early adopters end up owning technology that becomes obsolete without ever finding wide acceptance -- like LaserDiscs.
Smartphones seem to be in the first category. Products like the Apple iPhone and Google's Android operating system have pushed the smartphone out of the world of gadget geeks and into the mass market. In 2010, the first 4G smartphone for a major carrier in the United States made an appearance. It was the HTC EVO 4G, running on Sprint's WiMAX network [source: CNET]. The 4G network allows for faster data transfer speeds than other networks.
The Internet will continue to play an increasing role in communication. Voice over Internet protocol (VoIP) already plays a large role in several communication products and services. Sites like Facebook and Twitter allow users to communicate with networks of people. With the rise of the Web, people now have a platform from which they can address the world. In the past, only celebrities and politicians could address so many people at one time. Now, anyone with an Internet connection can do the same thing.
This may lead to changes in everything from entertainment to politics. Using the Web as a communication tool, people with aspirations may be able to find an audience more easily than ever before. It may not be long until a relatively unknown person uses the Internet to win enough support to be elected president of the United States.
So far we've looked at some fairly mundane advances in communication. But what about the distant future?

the bus was so late so i decided to walk. This is the first time i have walked to school so i felt excited. But not much, because i had to walk as fast as i could to get to school on time. The weather on that day was so nice that i planned to go fishing with my best friend in the afternoon. Sunddenly, i saw a little boy crying under a big tree. I didn't want to help him at first because i would be late for school. But then, i came over there and ask him if i could help. He said that he was lost and he felt so scared. I consoled him and lead him to the police station. Although i have been already late for school, i was still happy. About 15 minutes later, his mother came. She thanked me and hug her son.

It can occur in many ways: industrial activities like dumping waste which drains in the fresh water make it polluted; or agriculture activities like using pesticides, herbicides....; and the garbage that we throw everyday.
