World Population – Mankind’s Greatest Challenge

world population

One of mankind’s greatest challenges in the future will be the vast growth of population. Currently there are over 7 billion people inhabiting planet Earth. By 2050 estimates say there could be as many as 9 billion. By 2100 scientists estimate we could hit the 10 billion mark.

In the article from LiveScience, most scientists agree that the Earth can only physically support 9-10 billion people. Most scientists agree that by 2050 or 2100 we will hit over that mark. They also agree that we will make a u-turn before that time comes. In the article they also explain even with maximum efficiency the 3.5 acres of land could only produce enough food to support 10 billion people. With Water resources around the world that could run into another problem.

Producing more food to feed those who cannot afford food will only make the problem worse. We are currently producing more food to feed the malnourished in the world. One theory scientists are pondering is once everyone is feed it could have the opposite effect and there will just be more people to feed. The only way would be for those families and people to be able to control the amount of kids they want to have.

Already it feels like in some areas there just isn’t enough resources to go around. Most people only get a 1/3 of an acre to call home unless you are one of the lucky ones.

Man’s greatest challenge will be limiting the population growth of the future.


Why is Population a problem?

We have already established that the world can only support a certain amount of people. When the world gets crowded disease will spread, resources will become scarce and ultimately violence and wars could spread.

Not to mention people are constantly encroaching more on Nature. With our footprints expanding we are constantly destroying wildlife and the homes the animals have.

In one of our other posts, Increase Protected Land in the World, it states that only 15.4% of all land is protected from Human interference. Before we hit that tipping point we need to increase the land protected to 25% or 30%, preferably more.

There has been many articles how the world is entering another mass extinction, like this article from the Washington Post.

It pains me to see all the animals that are hit by cars. Our roads are going everywhere. It should be mandatory to built 6 foot fences along all the roads we build. As the population increases this will only get worse.

Someday they could look back and say there was once a time where animals lived in the wild. I do not want to see that day come. We still have a chance.


What is the Solution?

From an educated and moral standpoint the only logical answer can be to slow the growth of Earth’s population. Morally we cannot reduce the population, pending unavoidable wars, disease and famine.

The only logical solution can achieved through Education.

Most developing countries do not have access to education or contraceptives. We need to increase the supply of these things to countries that are booming with population. This would help women’s rights where is some countries they are being forced to have more and more kids. Some parts of Africa see a fertility rate of 9. That’s 9 kids to one mother that can’t support any of the children. We need to get women contraceptives in poor parts of the world.

Even in developed countries like the United States teen pregnancies happen and those living in poorer conditions do not have access to any form of contraceptive.

If we want to save the planet and keep enough resources to go around the best way would be to educate the poorer populations and those who do not have access to birth control methods.

Without this the world will continue to populate and people will suffer as a result. Mother nature and the wildlife of Earth will ultimately suffer the worst of it.
