God told Adam and Eve to procreate while they were in the Garden, by the way the tree is not the tree of knowledge. If the fall had never happened I believe we would not have had to worry about over use of the planets resources nor over population, God would have made provision for those things. I also think we would have not advanced into a tech world, actually things would pretty much remained the same, all our needs would have been supplied.
God loves those who believe and those who do not and the same goes for me, you have no choice in this matter. That puts the matter of total free will to rest.
