Thank you @crystalize, both for your vote and the very thoughtful comment. :c)

You make a very good point. Yes, culture does play a big role.
Simple life-style does too, and a simple comparison between meat eaters (such as myself) and vegetarian or even vegan individuals will show that my 'footprint' upon the Earth is greater.
Of course such mindset variances with respect to childbearing choices have an even greater impact and awareness is what might eventually turn the tide.
Thank you also for the link. :c)
