If they're afraid that the new expressway will bring hordes of people and pollute the water resources, then what they should do, within reasonable bounds, is allow the people here to build public facilities for visitors which will help minimise their impact on the local ecology, for example public toilets and comprehensive rubbish disposal. This would give people from outside the area more opportunity to appreciate Pinglin's idyllic natural setting.
如果害怕北宜高會帶來人潮、污染水源地，應該做的是讓坪林在合理的範圍內，建設更多方便遊客的公共設施，比如公廁及完善的垃圾處理，讓外鄉人有機會看到坪林與生態和諧共存創造出來的美麗。
