It seems that only when government decides it can afford tax in centives or production sacrifices is there any initiative for change. Where is industry's and our recognition that protecting mankind's great treasure is the single most important responsibility？ If ever there will be time for environmental health professionals to come to the frontlines and provide leadership to solve environmental problems, that time is now.
We are being asked, and, in fact, the public is demanding that we take positive action. It is our responsibility as professionals in environ mental health to make the difference. Yes, the ecologists, the environ mental activists and the conservationists serve to communicate, stimulate thinking and promote behavioral change. However, it is those of us who are paid to make tile decisions to develop, improve and enforce environ mental standards, I submit, who must lead the change.
We must recognize that environmental health issues do not stop at city limits, county lines, state or even federal boundaries. We can no longer afford to be tunnel-visioned in our approach. We must visualize is sues from every perspective to make the objective decisions. We must ex press our views clearly to prevent media distortion and public confusion.
I believe we have a three-part mission for the present. First, we must continue to press for improvements in the quality of life that people can make for themselves. Second, we must investigate and understand the link between environment and health. Third, we must be able to communicate technical information in a form. that citizens can understand. If we can accomplish these three goals in this decade, maybe we can finally stop environmental degradation, and not merely hold it back. We will then be able to send pollution dollars truly on prevention rather than on bandages.
we can infer from the first two paragraphs that the industrialists disregard environmental protection chiefly because______.
听力原文： At least eighty-one people are reported to have died during a fire in a handicraft factory in southern China. As we hear from VOA's Max Rusten many of those killed are reported to have been unable to leave the building because of locked doors and windows. "Beijing backed newspapers say most of the victims died of suffocation as they tried to escape from a three-storey a few kilometers from China's border with Hong Kong. They say factory managers locked windows to guard against theft and failed to meet demands from fire authorities for improved safety standards. Strong winds made it difficult for fire-fighters to put it out. Most of those killed are reported to have been young women. The fire is the latest in a series of fire-related accidents in southern China. Fourteen people died in a fire in an overcrowed dormitory last month. At least fifteen people were killed in an explosion at a dangerous goods warehouse earlier in the year. Observers in Hong Kong say rapid economic growth in southern China, particularly in the manufacturing industry, has outpaced the government's ability to maintain adequate safety standards. Max Rusten, VOA news, Hong Kong."
The news from China tells us that ______.

What might driving un an automated highway he like？ The answer depends on what kind of system is ultimately adopted. Two distinct types are un the drawing board. The first is a special-purpose lane system, in which certain lanes are reserved for automated vehicles. The second is a mixed traffic system: fully automated vehicles would share the road with partially automated m' manually driven cars. A special-purpose Jane sys tem would require more extensive physical modifications to existing high ways, hut it promises the greatest gains in freeway capacity.
Under either scheme, the driver would specify the desired destination, furnishing this information to a computer in the car at the beginning of the trip or perhaps just before reaching tile automated highway. If a mixed traffic system way was in place, automated driving could begin whenever the driver was on suitably equipped roads. If special-purpose lanes were available, the car could enter them and join existing traffic in two different ways. One method would use a special onramp. As the driver approached tile point of entry for tile highway, devices installed on the roadside would electronically cheek the vehicle to determine its destination and to ascertain it had the proper automation equipment in good working order. Assuming it passed such tests, the driver would then be guided through a gate and toward an automated lane. In this ease, the transition from manual to automated control would take place on the en trance ramp. An alternative technique could employ conventional lanes, which would be shared by automated and regular vehicles. The driver would steer onto the highway and move in normal fashion to a "transition" lane. The vehicle would then shift trader computer control onto a lane re served for automated traffic. (The limitation of these lanes to automated traffic would, presumably, be well respected, because all trespassers could be swiftly identified by authorities. )
Either approach to joining a lane, of automated traffic would harmonize the, movement of newly entering vehicles with those already traveling. Automatic control here should allow for smooth merging, without the usual uncertainties rent potential for accidents. And once a vehicle had set tied into automated travel, the driver would be free to release the wheel, open the morning paper or just relax.
We learn from the first paragraph that two systems of automated high ways______.
