I don’t find these suggestions very useful. First, don’t most schools already have these “new” courses? I’m most familiar with the curriculum where I teach, but we already have one or several courses in each of those named fields.
Second, I don’t see how the listed “problem-based” seminars are supposed to help. What legal issues do students study in their Word Peace class, and how does expertise in World Peace help students get jobs? Presumably students aren’t expected to practice World Peace law. And I assume no one expects that two-credit seminars will actually create world peace.
Third, if the problem with law schools is that students need these courses but don’t take them now, then the answer is to mandate these courses rather than simply offer them. At most schools, almost everything after the first year is an elective. Merely adding new electives that most students won’t take is at best a symbolic answer to the alleged problem.
