It’s a sign of the times: couples limiting their offspring, or choosing not to procreate altogether, with a view to saving the planet.
Or, at the very least, delaying its destruction.
That growing number of concerned individuals now includes two of our very own royals: the Duke and Duchess of Sussex.
In an interview with celebrated primatologist, Jane Goodall, for British Vogue, the young Duke shared that becoming a father in May had changed his perspective on having kids.
Now a father of one, when HRH referenced having children Goodall added "Not too many," to which he confirmed, "Two, maximum."
"I’ve always thought: this place is borrowed. And, surely, being as intelligent as we all are, or as evolved as we all are supposed to be, we should be able to leave something better behind for the next generation,” he said.
Describing the destruction of the environment as "terrifying," the 34-year-old believes, "We are already living in it. We are the frog in the water and it's already been brought to the boil."
