In that case, what happens to the extra 110 kilos of fertilizer? Some evaporates into the air, becoming acid rain. Some penetrates into the groundwater, or is washed by rain into rivers, contaminating the supply of drinking water to local cities and towns.
於是，那多出來的 110 公斤化肥，有些蒸發到空氣中形成酸雨，有些滲入地下水層，或者在雨水沖刷下進入河流，污染附近城市的飲用水源。
