JackShit I have to say I agree with you, even though it's clearly an unpopular view.
I come from a family of 4, and loved having so many siblings when I was young. Always thought I would have 4 or even 5 children myself, but my husband and I deliberately chose to stop at 2, even though I would have loved to have more. The main and over-riding reason for only having two children (i.e.: just replacing ourselves, in terms of the global footprint), was the impact on the planet, and its ever-rocketing population.
The organisation Population Matters says, "We cannot confront the massive challenges of poverty, hunger, disease and environmental destruction unless we address issues of population"
From the fast-deteriorating environmental health of this planet and global food production, to our own small island and over-burdened NHS, it is simply irresponsible to bury one's head in the sand about the population issue. If we carry on this selfishly, there is estimated to be at least another 2 BILLION people on the planet by 2050. How can the planet comfortably feed, sustain and care for such a bloated population? There will simply not be enough resources to go around. So everybody suffers, with hunger, thirst, illness, cramped and unhygienic living conditions, lack of employment, financial strains. The list is endless.
Sure, in Victorian times people had larger families...because many children perished before reaching adulthood. And there was less access to safe, reliable contraception. With modern drugs and healthcare, these are, thankfully no longer typical concerns - and average life expectancy is around 80-95 years.
It really doesn't take a genius to work out that if we all had 4 children living for nigh on 100 years, the planet is going to struggle to host so many needy inhabitants. An unfashionable view maybe, but if things don't change, I fear that time will prove its validity.
