For both theoretical and practical reasons, this is a challenge that will not be met easily or quickly. And, when it is met, the process will most likely be partial and uneven, accentuating differences and posing tricky coordination issues at the national, regional, and global levels.
从理论与实践上来说，这都是一个无法轻而易举解决的挑战。当面临这个挑战时，其过程很有可能是局部且不平衡的，它会突显出一些差异性，并在国家、地区及全球层面上产生棘手的协调问题。
