Overpopulation means that the number of a species has grown too large for the resources that support that species. There has been some concern about the overpopulation of the human race. The number of people living around the world today has grown dramatically in the last several decades but resources are still limited.
The Bad News about Overpopulation
Human population has been growing exponentially. In 1927, the population of the earth was only around two billion people. It has been projected that with current growth rates the human population will reach eight billion as soon as 2028.
The use of resources is often done without thought for future needs. That means that unsustainable logging and poor farming practices are depleting the soil. Overfishing reduces the resources for human consumption and for the wildlife in the region. Meeting the needs of the world population has pushed many people to deplete or misuse the natural resources found around the globe.
The amount of land in the United States that has forests growing on it is half of what existed when Europeans came to America in the 1600’s.
The number of people populating the earth means that more carbon dioxide is being released into the atmosphere. Many experts point to this as a factor for climate change.
The population grow of some regions has far exceeded that region’s abilities to provide. According to the UN there are over 89 nations that are currently unable to provide enough food for their inhabitants. Many of these nations cannot educate their population and as a result almost 1 billion people are illiterate in the world today.
The Good News about Overpopulation
It has been estimated that the world population occupies less than 3 percent of the total land mass of Earth. That means that you could technically fit everyone in the world into the State of Texas and still allow each person almost 1300 square feet of living space.
The rate of growth has been declining over the last few decades. Some regions are actually declining in population.
Figures have suggested that the rate of reforestation and land management has allowed for almost 100% of the world’s tree population to continue to grow.
Advancements in technology have allowed the world’s farmers to produce greater crops than ever before. Global food supplies have reached a surplus in all regions of the world, including developing areas. Only about half of the farmable land is being used at present.
The population grow is estimated at less than a 1% increase. Most experts believe that the Earth has the ability to absorb those numbers without impending disaster.
Many of the Earth’s resources still lie unused.
According to the United Nations Food and Agriculture Organization the Earth has the capacity to grow food for a population that has reached over 30 billion people.
There are some threats that can be caused by overpopulation. Most of the time these threats are regional and are more focused on the government policies of a region than that region of the Earth’s ability to provide the resources to sustain the population.
No matter where you stand on the issue of overpopulation, it is important that education be provided. Understanding the struggles of the world environment is the only way to begin adjusting to fix those struggles.
The focus for many is on the population numbers. More emphasis on sound agricultural practices and use of technology can help to bring even those numbers that are climbing at the highest rate into balance with the resources that are available.
Overpopulation occurs when the numbers of a species rise higher than the resources that can sustain that population. The overpopulation of the world is many decades off as long at the current population can work together to utilize the resources that exist.
