The world has been reeling from the financial crisis with reverberations being felt throughout the real economy on production, consumption, jobs and well-being. At times like these, we are all reminded of just how intertwined our future prospects have become and forced to reflect on how history has led us to our current circumstances.
The Need for Population Stability Too Many People Harms Us All We all want to have long, peaceful, and prosperous lives — to do this we need fresh water, healthy cropland for food, and materials for shelter and security.
However, being that we live in a finite world, there are limits on everything needed for a long, healthy human life. There is a limit to size of the pie. If more people eat from this proverbial pie, each piece must shrink to accommodate the growing number of people at the table. We always had more then enough pie to feed new people at the table, and more people were a welcomed sign of continued prosperity generally.
Today we have almost 7 billion people on our planet and we have taken up nearly every square inch of usable land as our populace has grown. Continuing to grow will make it harder and harder to sustain our population comfortably.
We are adding more and more people to the table but no longer have more pie and our pieces are beginning to shrink.
As our global pie of resources continues to diminish, our increasing population begins to be harmful to all of us. At our current growth rate we will have over 10 billion people on earth by If the world moves quickly to stabilize population growththe UN estimates we will peak around 8 billion people in and then decline.
Brown, Plan B 3. Biologist have studied the effects of different populations on their ecosystems as they grow.
As they grow, there are two routes a populace can take, regardless of whether it is a community of beavers or a community of people. Carrying Capacity vs Growth Outcomes The first route is a population explosion as resources are abundant food, shelter, et cetera.
As these resources begin to decrease the population eventually reaches the carrying capacity. At this point the area cannot sustain continued growth and the population levels out.
This means that birth and death rates in the future are relatively equal. The second scenario entails a population explosion that rockets past the carrying capacity and does not slow as resources begin to decrease. The resources dwindle faster than they can be replenished.
You can see that in the long run, this scenario ends with a massive die-off, because there are no longer enough resources for the bloated population to thrive on.
Worse yet, the population has taken the reserves needed to sustain the original carrying capacty and after a mass die-off a much smaller carrying capacity exists. Humans have highly variable consumption habits and as such the carrying capacity of our area Earth can vary. Before we hit that critical point we need to stabilize our growth.
The Population Limit How many people can the Earth support?
Our carrying capacity varies depending on our how much we consume. How much each person consumes will determine how many people can live on Earth. For instance, if everyone ate as much as Americans we would only be able to support 2. The Italians, on the other hand, live healthier lives with a much more varied diet, consuming half as much grain as Americans.
They have longer life expectancies and at their level of consumption we could support roughly 5 billion people. This means a significant change in the American diet and a more efficient distribution of the available food on the planet. Eat enough, not too much, mostly fruits and vegetables. Our diet would be significantly cut here in America, while increased around most of the rest of the world.
Our diet would not necessarily be beans and rice every night, but there would definitely not be as many steak dinners. Personal and Public Challenge Population stabilization is a sensitive topic in our society. Many hear the term and, incorrectly, associate it with abortions, childless families, and strict birth control mandates from the government.
There are family-friendly, politically safer ways to support a stable population.
