想請教各位,
有個問題想請教您, 以下的這個句子是我自己造的:
The citizens of that area have long ignored the threat of air pollution,
causing their health to become worse year by year.
想請問:
1. causing 也可寫成 ,which causes; 指的是ignoring 這件事. (不知是否正確?)
2. 如果我想要說明的是 air pollution 這個現像, 那這在個句子中, 我要怎麼用關
代來修飾呢? (是不是就用 which causes; which 前面不加逗點, 不知是否正確)
謝謝

which causes→which指的是air pollution, which causes →指的是整件事
