Hemrietta(aged 16):The biggest problem with the environment is the ozone layer(臭氧层); there's a hole,and it's getting bigger.It's made by cars and aeroplanes-things give off fumes.There should be law that you aren't allowed to go to school by cars because the fumes go up into ...
But now air pollution is destroying it and that has made a very big hole in the ozone layer(臭氧层).3. B This is very dangerous because it can cause cancer.Carbon dioxide( $$ C O _ { 2 } $$) in the air has increased a lot. 4. G It has formed a“blanket(毛毯)” around ...
Why are there ozone holes in the stratosphere? Why is the stratospheric ozone layer important for human health? How are humans damaging the ozone layer? Why does ground-level ozone form when its warm? Is the ozone layer good or bad?
While the healing of the ozone layer has taken longer than initially expected when scientists first raised the alarm about the ability of long-lived chemicals, known as chlorofluorocarbons or CFCs, to deplete the protective ozone layer, the new findings offer a rare instance of positive environmenta...
Reports on Japanese chemists' development of a technique to safely destroy ozone-depleting chlorofluorocarbons (CFC) by blasting them with sound waves in water. Technique as an alternative to cost...
The earth's ozone layer(臭氧层) is slowly but clearly healing(愈合), a new United Nations report said.So, what is the Ozone layer? Why is it so important to us? As a layer of ozone high above the earth's surface, it protects living things on the earth. It stops harmful radiation(...
But now air pollution is destroying it and that has made a very, big hole in the ozone layer. Too much harmful radiation from the sun passes 6 the hole and reaches the earth directly. This is very dangerous_7this kind of radiation can cause cancer.More carbon dioxide (CO2 ) Carbon ...
Proximity to the equator:The closer you are to the equator, the more intense the UV rays. Altitude:Higher altitudes mean you’re closer to the sun, which means more intense UV radiation. Stratospheric ozone: The closer you are to the Earth’s poles, the thinner the ozone layer and the ...
47. The 'true enemies of science, argues Paul Ehrllch of Stanford University, a pioneer of environmental studies, are those who question the evidence supporting global warming, the depletion of the ozone layer and other consequences of industrial growth.[参考译文] 环境研究的先驱、...
Discuss the depletion of our ozone layer. Why we should care, what is causing it and what can we do to stop it? Discuss the molecule ozone and its role as being both beneficial and harmful to our health. Explain the differences between "good...
