I do believe there is some moral value in the survival of the human race, or life generally. But the extent to which that applies is very situational. For example, as a concrete scenario that could cause the world population a few decades from now to be a few million lower than it would otherwise be, consider an education or economic development initiative in a poor country that causes its residents to want fewer children on average. This would not meaningfully hurt life's chance to survive or spread. If anything, it would slightly reduce the likelihood of various non-human species being driven to extinction due to habitat loss or pollution or whatnot. So I would consider the reduction in population due to such an initiative to be morally neutral, or positive to the (small) extent that it saved species or improved others' quality of life. Meanwhile, the education or economic development itself would of course be morally positive.
