Limiting factors of population growth

Answer 1

There are many including food and water supply but technology has allowed us to move resources from where they occur naturally to where we choose to live.

Technology and our ability to support a population larger than a hunter gather population is based on energy use.

Assuming we can control the many extinction threats we will reach a limit when we achieve a Type I level of civilization. This occurs when we are able to harness (or use) all of the suns power that reaches the earths surface. At that point we will have to begin working on a Type II civilization and try to harness all the power of the sun.

Answer 2

Energy is the weakest link in sustaining a growing population. The infrastructure we take for granted would collapse catastrophically without the benefit of cheap energy. The lack of understanding and disbelief are understandable as exponential growth is only understood as an abstraction. We, as humans, consume proportionally to growth as the world population increases exponentially.

Even though we have only used half of the proven oil reserves, the other half will be gone in about 25 years. Natural gas will be gone as well. Coal, our saving grace, will be gone in less than 150, but not without a certain ecological cost. Nuclear fuel will sustain total world power consumption of 10 Tera Watts at current levels for only 10 years.

Shale and other scavenging methods are short lived measures.

Fusion is the only option, but a really good one.

Without energy we are done. Think you can adapt?

Can you adjust to an agrarian society? Work sun up to sun down. Walk to work or ride a horse. Ride a bicycle you say? How will you get the rubber? Latex comes from trees that only grow in the tropics, transported on ships that require enormous amounts of fuel.

Fuel for tractors? Fertilizers that make food production so abundant come from natural gas. Organic farming? Good idea, much lower yield though.

Without energy food production and distribution will go down. Malnutrition and starvation will pervade on a scale previously unknown. The poorest will mass migrate and the sick and starving people will spread with disease. (People get sick more when they are starving. Immune systems are metabolically expensive.)

Limited food production will limit sharing of ever increasing numbers of hungry mouths. War happens next with burning of enemies fields who can not be defeated and will not give food willingly. More starvation. More disease, more war. Crops that are nutrient deficient are more susceptible to disease. Pests will abound on weakened crops that are barely worth eating.

There is only one factor. Energy.

Answer 3

Some of the factors that limit population growth includes parasitism, competition, predation, space availability and resources such as oxygen, water and food. The control of population growth is usually based on the limiting factors and the population interaction within a given ecosystem.

Answer 4

Shortage of food and not enough space. Think of China, they have a population of about one billion people, so now they have a law that a family could only have one child, if they happen to have two then there are consequences.
