I’m honestly not certain—I don’t believe we’ll solve any of these problems by a degrowth approach, so the only way to get a real solution is via innovation and/or adoption of solutions. More people would help with that, but also would contribute more to the problem in the meantime. I think whether the sign was positive or negative might depend on the specifics (eg, I think if environmentalists have fewer kids because of a fear of overpopulation, that will generally be bad for the environment).
