At least environmental pollution is something you can see. What you can't see are problems that run even deeper, have greater impact, and are harder to fix: soil acidification, exhaustion of the nutrients in the land, and sacrifice of crop biodiversity.
環境污染還是看得見的破壞，看不見的，是更深層、影響更廣泛且難以挽救的，如土壤酸化、地力枯竭、作物多樣性被犧牲。
