Computers speed up functional processes which should be used to make life easier. Occupational health should always be considered regardless of whether computers or bone thumping typewriters are used. Remember computers are simply a tool. Tools can be used for good or ill. Some of us don't drive cars but very few of us can say that they have never used a car.
Cars cause a lot more pollution.
Computers can even be used to monitor environmental safeguards. Photocopy machines have CPU chips. There is an argument that computers have created an information hierarchy. This gives me hope because we are still at the stage where we can get hold of these information resources. If we fail to emancipate ourselves, we remain the ignorant victims of the computer age.
