Two news stories are raising the profile of a growing movement to push back against having children.
One Colombian couple, Natalie and Andres, took to Facebook to make a firm stand against having children, posing with a photo for his vasectomy appointment.
Their reason? As well as the usual reasons around having disposable income, the two say they want to "contribute to the conservation of the planet that is so over-populated and damaged."

Their claims raised eyebrows and propelled them into the global spotlight, with over 56,000 people sharing their post and over 1,600 commenting. 
It comes as one man has made global headlines for taking action against his parents for giving birth to him. 
Raphael Samuel, 27, from Mumbai, believes that his parents should have asked for his permission before conceiving him, likening the actions as being akin to kidnapping and slavery. 
His mother told the DailyMail she is pleased her son is a fearless, independent thinker, and will accept she is to blame if he can provide a "rational explanation" as to how they could have asked his permission.
