Aah, but in all that you wrote here you didn't use the word 'better', which was what i was talking about.
Better is an opinion and is not based on hard data.
Better is always from some(ones) point of view.
And i agree with most of the rest of your post, hard facts are hard facts.
So hards fact are telling us
it is better to take care on our offspring then to abuse it.
They are also telling us
it is better to have energy then dont have it.
I dont see any opinions attached. It is just semantics.
