Bill McKibben, who has been called “probably the nation’s leading environmentalist,” supports a policy limiting families to just one child per couple.
In his 1998 book “Maybe One,” McKibben suggested families should only have one child in order to reduce their family’s impact on the environment:
“The problem, of course, is that now we live in an era- maybe only a brief one, maybe only for a few generations- when parenting a bunch of kids clashes with the good of the planet.” — Maybe One, p. 196
McKibben argued that single-child families “make sense as a cultural norm”:
“I’ve argued strenuously that we’ve reached a moment when single-child families make sense as a cultural norm.” — Maybe One, p. 204
