Productivity is the basis for all law, human and non-human. To a point, the more humans we have, the more productive we are and that's why original human and non human life did not kill each other. Not because a book or a yet to be seen man in the sky told them to.
Wrong, again.
Let's use your parents as an example. I believe you said once that they were strict in their house rules. (if not then forgive me for assuming) If this is not the case, then at least bare with me.
They established certain rules for you all to abide by and they also provide sustination for you. Should you chose not to follow the rules established then there are consequences. Now, you can chose to either take that consequence and not break that rule again, or you can kill your parents and establish your own rules. (If you are old enough you can leave and also establish your own rules) But let's assume that you are living in the early times of man as an "original" human as you stated above and you can't just pack up and go get an apartment. What do you do? I assume that whatever the case, in the end you will either agree on rules of behavior, or you will kill or dominate your parents. Should you not kill them, then why? Is it because of loss of productivity? I doubt not.
That is the fundamental truth of Mans' existence. There are only two ways for men to avoid and/or settle disputes: violence, and contract.
Cheers to places like Africa where they can't grow any vegetation, can't get clean drinking water and rely on the rest of the world to provide for them. It means people can't live there without the aid of others.
Has it been that way since the beginning of time?

From what I understand, they were fully capable of susatining life before the rest of the world showed up.
There's more to human life that just space. The world will run out of resources and we already are, a clear sign of over population.
Care to elaborate that one? Again, we have plenty, but it doesn't always reach the places it should.
One figure provided by Soundvision.com estimates that over 41 billion pounds of food has gone to waste this year. Household food wastes alone adds up to about $43 billion. A study done in Arizona estimates that single household wastes about 14% of their food.
This one says that over half of all food produced worldwide is wasted:

What makes you so sure that He hasn't already saved us from a destructive meteor?

The counter productive are not "loved" and are shunned from society.
In this case, you have nothing. You don't know for sure that a homeless man is not loved. Also, I don't shun homeless people. Who am I to judge them, as I don't know what they've done to get themselves in that position.
So North Korea stops the US from sending food to Africa? What about the millions living in poverty in the United States? Is North Korea stopping that too?
Damn, you really ARE that ignorant aren't you? N. Korea stops any foriegn nation from sending food to N. Korea. Also, US DOES send food to Africa. I don't know why you think that we don't.

As far as people living in poverty here on our soil, there are programs and charities that help them as well. Don't be so closed minded and think that the US can solve the world's proverty as well as our own. No wonder people despise us; because we're put on some kind of pedestal and expected to work miracles and when it's just not possible, then everyone holds grudges.
You and Ohio seem to be living in a fantasy world where everything is perfect and God will save us if things go wrong. I don't know how you can guys can trust something you have never seen but while you guys are doing that, I will try to improve the earth's productivity.
Nope, I just live in the real world and make due with what I've been provided with. You can continue to try and improve Earth's productivety by flaming every Tom, Dikc, and Harry on Wii Unite (or punch numbers as an accountant, I believe), while I continue to do my thing, go to work, raise my family, and strive for Heaven's presence.
