问题如下：
In underdeveloped countries, one of the solutions to water scarcity is wastewater treatment plants. When we evaluate the effectiveness of wastewater treatment plants, which of the following should not be considered as a concern?
选项：
A.Wastewater treatment poses significant externalities to local wildlife
B.Wastewater treatment is highly capital intensive
C. Wastewater treatment requires enormous costs
D.Wastewater treatment requires enormous skillsets to operate the plant
解释：
污水处理是高度资本密集型的，建立和运营的成本很高。它还需要熟练的工人来操作。对当地野生动物的影响并不是污水处理厂的关键问题之一。
污水处理厂就自动联系到排污，影响当地生物了
