What if you groom your kids to be more focussed on fixing a large scale problem? Either to be activists, conservationists, researchers and scientists working on green solutions etc...? What if your child was going to be the one to contribute the missing piece of the puzzle, to some fantastic renewable, green energy source? And your child not being there means that the contribution comes from someone else 10 years further on. But in those 10 years the world is thrown over the point of no return?
A far fetched scenario, but it is one to consider. Anyway, I would much rather have someone procreate, who is globally conscious to the point of not wanting kids, due to the possible negative impact; Than have someone procreate for the ****s and giggles of raising a child. At least the former would have a chance of raising a kid that could contribute to the saving of our home.
And as I have said before, if all of the people that are educated enough to realize what our rising population is doing to the planet; simply stop having kids in order to balance the scales with the impoverished that pop them out like candy. Then in 50 years we will have a global generation of under-educated and overbreeding people, starving and bumbling through life.
As the saying goes, that is like cutting off the nose to spite the face.
