SCIENCE AND TECHNOLOGY

Through the centuries, people's lives have changed enormously. Today, the way you live is completely dominated by technology, from the electric toaster that produces your breakfast to the bus that takes you to school, to work,  the computers you use for learning and playing games, and the television and video you watch in the evening.

Science and technology have helped us in lots of ways. Because, of them, we can grow and distribute  food chaeply, manufacture clothing and household goods in huge quantities, treat illnesses of all kinds, and travel from place to place quickly.

But we have to be very careful to use the technology we have in a responsible way. The same knowledge that saves lives and makes our world better can also lead to the development of powerful weapons and chemicals that can harm us and our planet.
