Especially as it will not just be the degradation of environment that needs addressing in the future, but the waste of all the resources as this will drain a region's stamina for long-term sustainable development.

问：这个句子中，as it will not just be the degradation of environment that needs addressing in the future, but the waste of all the resources 这是as引导的并列的原因状语从句吗？可是其后“as this will drain a region's stamina for long-term sustainable development.”这又是一个原因状语从句吧？那我想问这段文字的主句在那？
