Toni, from Taunton, Somerset, says: "When I was 21, I considered sterilisation for the first time.
Because when Toni terminated her pregnancy, she did so in the firm belief she was helping to save the planet.

He refused, but Toni - who works for an environmental charity - "relentlessly hunted down a doctor who would perform the irreversible surgery. At the age of 27 this young woman at the height of her reproductive years was sterilised to "protect the planet".
"Every person who is born uses more food, more water, more land, more fossil fuels, more trees and produces more rubbish, more pollution, more greenhouse gases, and adds to the problem of over-population." While most parents view their children as the ultimate miracle of nature, Toni seems to see them as a sinister threat to the future.
