Finally, eight years ago, Toni got her way.I've run into milder forms this myself, from "replacement only" people who consider having more than two children to be a crime against future humanity. I suppose this is only taking things one step farther.
At the age of 27 this young woman at the height of her reproductive years was sterilised to "protect the planet".
Incredibly, instead of mourning the loss of a family that never was, her boyfriend (now husband) presented her with a congratulations card.
While some might think it strange to celebrate the reversal of nature and denial of motherhood, Toni relishes her decision with an almost religious zeal.
"Having children is selfish. It's all about maintaining your genetic line at the expense of the planet," says Toni, 35.
"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.
The ironic thing in all this is that in elevating the world's ecosystem to something so sacred that it must feel no impact from humans, such extreme environmentalists turn humans into an exception from the rules that govern other species. Most species, if provided with vast unused resources, will reproduce in order to exploit them as rapidly as possible. If later the species population runs out of resources, famine reduces the population back down to sustainable levels.
Humans, having the intellectual capacity for forsight and not liking the idea of maxing out resources and experiencing a major dying-off, wisely wish to avoid consuming resources in this sort of unthinking fashion. We seek both to avoid a situation in which resources suddenly run out, and to avoid turning the regions we inhabit into unpleasant places.
And yet, this idea that we should actively seek to erase our impact on the world by erasing (or vastly reducing) ourselves as a species seems to deny the physical part of our nature. As well as being thinking creatures, we are also a species, and for what do species exist other than to be fruitful and multiply?
