和罗马俱乐部一样，今天的气候科学家反对要孩子的理由是增加地球人口会导致环境负担。
Just like the Club of Rome, today’s climate scientists make the case against having children by pointing to the environmental burden caused by adding to the planet’s population. Most analyses use the approach set out in a 2009 paper by Oregon State University’s Paul A. Murtaugh and Michael G. Schlax, which holds each parent responsible for half of every child’s projected lifetime CO2 emissions.
