2. Recycling

Recycling is the processing of used objects and materials so that they can be used again. About 50% of rubbish from homes and factories contain materials that could be recycled. Recycling saves energy and raw materials, and also reduces damage to the countryside.

Glass paper and aluminium cans can all be recycled very easily. Many towns have bottle banks and can banks where people can leave their empty bottles and cans for recycling. A lot of paper bags, writing paper and greetings cards are now produced using recycled paper.

3. WE CAN'T STOP THE GREENHOUSE EFFECT, BUT WE CAN

SLOW IT DOWN

There are several ways to do this:

4.

Conserve Fossil Fuels - Some countries have already begun. Each person in Japan, for example, uses only 50% as much coal, gas and oil as the average American.

Conserve Rainforests - The Earth needs more trees, not fewer. South American, Asian and African countries must protect their rainforests, not cut them down.

Use Natural Energy - 20% of the world's energy already comes from the sun, sea and wind. To slow down the Greenhouse Effect, that number must rise to 50% in the next 20 years.

Ban CFCs - This is beginning to happen. Many companies have already banned CFCs.

1. Read the text and decide on the best title for it.

When you are preparing for a computer career, keep one thing in mind: change,

not continuity, is the norm. Throughout the ages, mankind has always managed to

find the technology to achieve its goals. Whatever our personal views on the future

might be, most of what is impossible today will no doubt become commonplace at some time in the future. New technological developments will give new opportunities, create new kinds of jobs—and make old ones obsolete. The scientific and technical revolution is sweeping the world.

Today, hardware and software technologies allow people to work and play

together in interactive and immersive 3-dimencional environments. Technology is also offering us new ways of exploring both the real world and the 'virtual' world of Cyberspace. Technology is reducing the need for travel and transportation, enabling us to gather information from anywhere in the world within minutes, to cut down on the use of material resources and allowing us to perform many activities simultaneously. Time and space are becoming compressed as communication networks bring us closer together and enable the formation of 'virtual communities' where, for instance, colleagues around the world work together via their computers in shifts. This can result in an uninterrupted 24-hour activity.

Consider computer information systems (CIS) professionals. Twenty years ago, they worked in a central computing facility, where they wrote programs or designed systems. When the microcomputer came along, these professionals had to decentralize. Nowadays instead of writing programs, CIS professionals installed software packages, customized those packages to work best for the user, and acted as resident computer experts for the user.
