We live in 21-th century and we can’t imagine our life without technology. We every day have a contact with it. Now technology is main part of human civilization.
Technologies significantly affect human as well as other animal species’ ability to control and adapt to their natural environments. The human species’ use of technology began with the conversion of natural resources into simple tools. The prehistorical discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale.
However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons.
We must be careful, because technology can not only help or make our life more easy, but also can destroy every thing what we did.
