But it gets even worse. **Let’s say that the entire world suddenly converted to the Catholic way of thinking about abortion and contraception. **…
Maybe you are not understanding the full extent of Catholic teachings?
… Even with those caveats, every 25 years, the past generation would produce a new generation that’s 128% larger than the previous. In a 100 years, the new *emerging generation *would be 6 billion strong. Let’s say that the world life expectancy improves to 75 years old. The total population in a 100 years would be 14.39 billion…In a thousand years, that new generation would be 37.700 trillion, with a total population of 90.478 trillion. That’s over 10,000 times larger than the new generation of today…
Maybe you should calculate backwards, I did that once and I think the backword calculation indicated it took 500 years to obtain the current world population? ( I used 5 kids per family). The point is the calculation is theorical and varies greatly from reality
 
Sigh not the we could all live in Texas story again. I am tired of arguing against this point though. But I will just say this…there is a pretty big difference between new york city and having the entire world population in Texas.
The point is not that we should all live in Texas (for one thing, I wouldn’t want all the folks who screwed up places like NYC and Chicago and Boston and D.C. and the Left Coast to go and screw up Texas :D) … the point is that we’re nowhere near running out of space or resources. Besides, the population of NYC is not evenly distributed and there are also plenty of folks who work in NYC who don’t even live there.

“Data in regard to the earth: Land area, 148.847x106 km2, 57.470x106 sq mi.”
(From Weast, Robert C. CRC Handbook of Chemistry and Physics 61st edtion. Chemical Rubber Co., 1981: F-202)

6.8 billion / 57.47 million sq. mi. = 118.3 people per sq. mi.

At 640 acres per square mile, that’s 0.18 people per acre (i.e. 5.4 acres per person)
 
Exalt,

Your posts are always entertaining!

You make the statement that “if everyone converted to the catholic way of thinking (paraphrase)…” This is classic leftist utopian thinking. News flash for you. It’s never going to happen! The wide road will ALWAYS be the road to destruction, the road to heaven will always be the narrow road.

Your hypothetical scenario is indeed not sustainable, but catholicism is NOT utopian. We don’t EXPECT to achieve heaven here on earth. We’re on earth to be prepared for heaven in the world to come.

So there is no need to look forward to “what if” scenarios that will never come true. It is only necessary to look at the effects of faithful catholic living RIGHT NOW in the present day. The facts are that catholics in the western world do civilization a major service by keeping populations closer to at least replacement levels than they would be if everybody jumped on YOUR bandwagon. Your philosophy is leading to an impending demographic nightmare of huge aged populations with few working folks to support them. Nice work. 😉
 
This reminds me of a research paper I wrote about Margaret Sanger, the founder of Planned Parenthood. She followed the Malthusian’s theory, which was that while human growth is exponential, resource growth is linear. That theory is generally not accepted these days, as far as I know.

Either way, abortion and birth control are immoral, and God will always provide. Remember the verse about the sparrows? God provides for them, and we are infinitely more precious in his eyes.
 
Huh, no matter how much we share our resources, i don’t think you understand how the food is produced. We are able to grow more food, because we have acess, to more resources. We use those resources to grow more food, to keep the growing population. But sooner or later we are going to tap all the resources and what are we going to do next? Any ideas?

Anybody, that knows about math, knows this. A linear growth rate will always be overtaken by a exponential grow rate. No matter how small the expornential growth rate, and no matter how large the linear growth rate it will always be overtaken sooner or later.

We don’t know when the end of the world will come. For all we know, it may not be cuased by god, but by some idiotic thing that humans did. It is our responsibility to make sure that we survive till the end. And it is our duty, to protect the planet we live in. I’m not sure i remember correctly, but i’m pretty sure god said he would punish whoever tried to hurt the earth. I don’t remember correctly, but i’m sure there is passage like that.

You assume that the rates will constantly grow. Many made the same mistake in the stock market–expecting only growth. Sorry to remind you of this, but people die. There is no guarrantee that current popoulation rate will continue to grow

Much of the population growth is because of the advances in modern medicine. Good medical care helps more humans survive infancy and childhood. It also helps people live longer as adults. However, despite all our medical advances, the number of anti-biotic resistent bacteria is growing. Some place an awful lot of trust in modern medicine to cure all illnesses, but doctors are not God.

Doctors and other medical professional often want to play God, deciding who lives, who dies, and who reproduces. Those who fear overpopulation rarely express their concern about reproductive procedures such as IVF, sperm & egg donation, surrogacy, etc. Infertility is an increasing problem in the population. Infertility can occur because of physical problems or because of sexual lifestyles “choices” that are inherantly infertile. Modern medicine attempts to treat infertility by violating Catholic moral principles. Not co-incidently they violate the same sexual morals that tell us that contraception is wrong.

Catholic moral principle recognize the dignity of the human person from conception to natural death. We know that God is ultimately in charge of every person on this planet, and we know He allows us to share in caring for His Creation. Yet we do not have some grandeous notion that we are immune to death while having ultimately control of life. There is no guarantee that the population rate will continue at it’s present course. If you fear it will and advocate contraception to attempt to change the rate of population growth, you may be unfamiliar with the value of each human life and the reality that human life is fragile.

As a mathematical statement this is true because mathematical terms are constant. In the real world, however, change is the only constant. Yours is the same argument Thomas Malthus suggested two hundred years ago to warn of impending massive starvation due to population growth. Since then population has exploded and most countries are now better fed than ever; the exact opposite of what was predicted then. There is no reason to believe that current predictions based on the same flawed argument will fare any differently.

How about considering this. A population cannot outgrow the resources to sustain it, so we will reach a state where people will simply be born and starve to death, or freeze or die from sickness etc…
No need to worry about overpopulation, even if it was to occur it would eventually thin itself out from mass death and reach equilibrium again. Overpopulation is a great problem for us to solve and will no doubt lead to the development of great new technologies to meet our demands.

I think if we can continue to multiply like bacteria we should go for it. The skies are the limits, we are humanity and we are awesome…

Yah who cares about the potential mass starvation and death from diseases! Lets be like bacteria! 😛 :rolleyes:

Man has a remarkable ability to produce the food he needs. Consider how populated the Earth is and how small a percentage of farmers and farmland manage to sustain the needs of humanity. Consider also how man is blessed by God with industriousness. Now compare to such abilities as has historically been witnessed. Therefore, unfounded that people “*will *reach a state where people will simply be born and starve to death…” due to not being able to figure out how to provide for themselves.

Earths resources do have a limit. There is a point where humans will no longer be able to multiply. That may be another 6 - 10 - 20 billion people away, who knows, but like any population there is a limit. There is a physical limit to how much food we can produce. Unless we start occupying and terra-forming other worlds.

Yep exactly there is only so much ariable land only so much water that is usable for drinking and argriculture. So on and so forth and since we are a long ways from terra forming other worlds much less colonizing them…we need to make the one we have last. And yes there is human ingenuity but people need to realize we aren;t Gods…even humanity has limits…there might not always been a new techology or what not that bails us all out.

Well I could have said rabbits. It was just a figure of speach. If people only had as many children as they could support then this would not be a problem. And without a problem we would have no need for a solution.

lol I didn;t mind the terminolgy and yeah I admit I wasn;t sure on your position at first. I have heard too many people who seem to think that we could multiply like rabbits or bacteria and think we would just be fine. That we would always find a way to increase productivy that we always manage to invent some techology to bail us out just in time. But yeah I agree

So if there were approximately 20 billion people (roughly seven times what there is now), we would need seven times the amount of farmland? Did you know there is plenty of land available to accomodate this? No need for terra-forming.

Nonsense. There is plenty of ariable land and good fresh drinking water. Can you guess how many people it would take so there wasn’t enough drinkable water?

So what would you propose?

While the rate at which the earths population grows does resemble an exponential function, so does the rate in which information doubles. It is rumored that as we speak, information doubles every two to four weeks, and this rate continues to grow as we obtain new and more powerful computers and technologies. This new information and technology should allows us to expand our technological abilities to accommodate a growing population. Bearing this in mind, I have a great deal of hope revolving the survival of the Human race and the resources of our planet.

Granted, as our ability to feed the planet increases, so does our ability to destroy human life with the latest and greatest of our weapons of war. Yet, given time, i suppose this to is a problem which is not beyond our ability to solve.

Cheers,
Scout

Regardless there is a finite point at which there is not enough physical material to support X amount of humans. Whatever that number is. I was just using 20 billion as an example. At some point Terra-forming would be required.

Well let us assume we are capable of turning all of the water in the oceans drinkable and recycle instantaneously all of the water a human body excretes, regardless of how gigantic the number seems it would still be finite…
