‵地球暖化百年業，千秋萬代在今時′你認為呢句話點解?.

應是與環保有關的, 即污染地球用很短的時間就可做到,但要保護地球,就算由現在開始都要經過很多代。

everything is not appear in a sudden, everything need time to form. Just like global warming are not happen in a few year but is because we don't protect the Earth for many years.

I don't know is it correct or not but I hope it still can help you! XD
