[求助] 英语解释

The new research has profound implications for the environmental summit in Rio. Among other things, the findings demonstrate that dramatic climate change is nothing new for planet Earth. The benign (宜人的) global environment that has existed over the past 10,000 years—during which agriculture, writing, cities and most other features of civilization appeared—is a mere bright spot in a much larger pattern of widely varying climate over the ages. In fact, the pattern of climate change in the past reveals that Earth’s climate will almost certainly go through dramatic changes in the future—even without the influence of human activity.
The message the author wishes to convey in the passage is that ________.
A) human civilization remains glorious though it is affected by climatic changes
B) mankind is virtually helpless in the face of the dramatic changes of climate
C) man has to limit his activities to slow down the global warming process
D) human civilization will continue to develop in spite of the changes of nature
答案选C?求解释，真心认为应选B
