Will the ozone layer disappear? Where is the ozone layer within the stratosphere? How many ozone layers does Earth have? What happened to the hole in the ozone layer? How much of the ozone layer is destroyed each year? Is there a hole in the ozone layer?
The ozone hole is a large area of thin ozone layer in the stratosphere formed due to the depletion of ozone due to CFCs. Ozone hole is seen in the Antarctic region.
根据第三段the presence of ozone-destroying chemicals such as chlorine(氯)in the atmosphere--from human activities - caused the hole to form.破坏臭氧层的化学物质的存在,导致了这个洞的形成,比如大气中的氯——是人类活动产生的,所以 " 人类活动是产生破坏臭氧的化学物质的主要原因" 是对的。故选B。
