Genesis Chapter Nine 'be fruitful and multiply"

In Verse 1 we find God giving Noah the command to “be fruitful and multiply” The same command that was given to Adam. The question is, “Is this command still in effect today! And what does “multiply” mean? I am not sure, but it is interesting when we consider what people are being told today, that we should NOT multiply because there are too many people on the earth! It would make sense that when there were just a few people on the earth that there was a need to ‘multiply.’ But when did that change? What is the number that this earth can reasonably sustain? I don't believe that the world is being overpopulated. That is one of our typical media myths that the Christian church has bought into like so many other myths. If we took all the people on the earth today and gave them three square feet how much land would they take up? Less than half of the city of Jacksonville Florida! All the people in the world, could be given 1/3 acre of land which could provide enough to support themselves and they would all fit within the continental United States, leaving the other five continents empty! There are 52.5 million square miles of land area in the world, not including Antarctica. The problem is not a lack of resources, but greed.We have been told that the greater the population density the lower the standard of living. Japan has a population density of 800 people per square mile, yet they have a higher per capita income ($4,450) than India, which has 511 people per square mile ($140). West Germany’s density is 636 per square mile, the United Kingdom’s is 593, and both have a higher per capita income than India. It is obvious that population density itself does not necessarily mean poverty. Let’s look at India with its population density. It does not lack food. It lacks the one true God. Every one of their sacred cows eats enough food to feed 7 people. There are two hundred million sacred cows in their country. If they would just stop feeding them, they would have enough food to feed one billion, four hundred million people. They have enough food to feed 1/4 of the world's population!Dense population does not mean poverty. Greedy governments and false religions cause poverty. This world has plenty of resources to handle the population and its growth.
