Population Growth And Water Supply

Without having to think too much about it, there’s no doubt that at a much earlier time in human history, there were less people spread as evenly throughout the globe as there are today. It’s common sense to also think about how a person was to survive at that time, where they would need to be close to a food and water source.

With demand came competition of the most primitive kind and in order to control this, as system of laws were put into place. These too have become more complex as the population increased along with how a person is to get water no matter how far away from a water source they are. Here, we look at these developments in population growth and the water supply.

Long Distances

As mentioned; the closer populations were to a water source, the more it increased the population. This is how things started in the very beginning before there were fast and easy ways to transport from one distance to another.

When a water source was exhausted or something happened to it, it would cause the population to relocate somewhere else. If the conditions didn’t threaten life too badly, the transition was easy to do. But population was also affected depending on the distance they would have to travel to find that source. It could take generations before a survivor would be able to find one and then life would continue with new challenges.

Survival Tactics

When a person is put to the survival test, they will learn rather quickly through trial and error -- sometimes at the risk of death -- how to get by with the bare minimum. This is why when a person who’s been raised in an urban environment is put in a rural one, they’re following the same process of learning how to survive as opposed to one who already knows where to find water sources in nature.

Desert plants such as the cactus is a good example of a water source in the driest environments. Unless a person knew to seek water there at the beginning, another person would probably die of dehydration right in front of cacti and not know it.

In other extreme cases, the surface of objects that forms condensation in certain climates or even waiting for rainwater provided humans with knowledge that they could survive longer and to manage that over time could only naturally create a system that would ensure the survival of even larger populations.

Bringing The Water To You

If you were to look at the evidence left behind from ancient civilizations, you will see some form of simple irrigation design that allowed the collection and the redirection of water into places it was needed. These channels were established for crops, hygiene and drinking.

The discovery of metals, the invention of refinement and other new technologies along with trial and error created the pipes, faucets and other forms of transport that would bring water to the driest places. Now, rather than be close to a body of water all of the time, population increased evenly into other regions and with it more developments that would ensure the survival of even those groups. Which is taken for granted and overlooked every time someone turns on a faucet and yet never have to see a body of water in their life time.


It’s already been thousands of years since these developments have evolved to where they are now. It’s very easy to imagine with the changing of laws and potential challenges that come with population growth that the idea of overpopulation becomes less apparent. What was once a limited resource is now limitless.
