This article argues that this research program [longevity treatement] is much more risky or less beneficial than its proponents argue. In particular, they tend to underestimate the concerns associated with the potentially drastic population growth that longevity treatment could cause. The ethical benefit often ascribed to longevity treatment is that such treatment would add more subjective life-years that are worth living. However, in light of contemporary environmental problems, such an increase of the human population might be reckless. Drastically reducing fertility to reduce risks associated with environmental stress would make the benefits of such technology much less compelling.

I have a paper from a few years ago arguing a similar point. https://iopscience.iop.org/article/10.1088/0031-8949/89/12/128005;jsessionid=7EACB368D908AD6B0EC00F6688E725DD.c2.iopscience.cld.iop.org#metrics
