I think it's a complex social issue with a variety of causes and effects.
One major problem with society is that we now have a generation of parents - and i'm talking the 30 - 40 age-group here, who have no real parenting skills. The solidarity of the extended family has broken down and a lot of couples are isolated and unable to cope with adult life, never mind with babies and children.
I believe that sex education in all its forms is woefully underfunded in schools, and virtually non-existant in homes and families, so yes, a large number of young people are totally ignorant of the concept of conception, or its prevention.
We have a generation of young people to whom 'things happen' because they are never taught motivation, self belief, self reliance, ambition, or any of the building blocks of an aspirational culture.
They sit around, bored, discover sex as a diversion from tjhat boredom, and create thildren they neither want, or can care for.
The answer?
A good start would be for the government to upend its education policy.
Instead of its on-going obsession that fifty per cent of the population want to go to university (they don't!) put that mountain of money into nursery and child care.
Start employing nursery nurses who are trained and motivated, not teenagers on minimum wages who fall into nursery jobs because they don;t know what else is there and have a vague notion that they quite like babies.
Build a society of respect and caring from the ground up - from babies, to toddlers, to little ones, to teenagers,to adults, and let that thread of self-worth stop the rot in our culture.
Wil it happen? Not in my life time!!!
