In its most basic sense, the word “world” describes the totality of existent entities, all to which the word “being” does not apply. In other theories, the world is described by the natural laws that it obeys, and some even speak of a “plurality of worlds”. A more specific usage, yet still very common, is used to describe the cosmos as having four distinct phases – morning, noon, evening and night. These definitions have led some philosophers to refer to the world as “the world around us”, while some others speak of a “cosmos of worlds” – an idea that attempts to give substance to the apparently indeterminable nature of the world.

The recent breakthroughs in technology have provided humankind with several new opportunities, which has led to an increased interest in understanding the relationship between the world and the human mind. One of the most important breakthroughs was the discovery of the so-called “Worldwide Web” during the early years of the 21st century. With the invention of certain sophisticated web servers and browsers, the entire world can be accessed from any place on earth. Millions of people from all over the world are using the World Wide Web every day. For this reason, it has become a popular topic for many research papers.

The growth rate of world population has significantly risen over the past few decades, giving rise to the issue of overpopulation. The issue of overpopulation is also one of the major concerns of the world’s sustainability. To put a stop to excessive resource consumption and deplete the non-renewable resources, experts have come up with different solutions such as carbon trading, carbon neutralization and nuclear energy. Still, the exponential increase in the world population poses great challenges for the scientists and researchers all over the world.

There are several factors that lead to the growth rate of world population. Experts believe that the major cause is the rapid urbanization happening in various parts of the world, resulting to the creation of bigger cities and towns, and resulting to an increase in the labor force. Population centers like New York, Los Angeles and Chicago have seen an influx of several hundred million people in just a short span of time. While some of these people come to these cities in search of better living conditions, others are just escaping the poverty and hunger of their native places by crossing the seas and arriving in the United States.

Aside from the rapid urbanization, another factor that contributes to world population growth rate is the rise of technological advancements. Thanks to the Internet and other technological innovations, the world is now able to develop and produce goods at a much faster rate than the normal rate. With the help of technological advances, the world population is now able to enjoy a higher standard of living. Thus, experts predict that the world population will continue to grow in the future, reaching as high as the 8.6 billion mark in the next few years.

In order to get a clear picture of world population estimates, it is important to look into worldometers, which are very useful tools used by demographers to determine world population size. These demographers use a variety of methods and statistical programs in order to come up with world population estimates. Some of these programs involve combining different types of measurement, while others base their calculations on known facts about the world population. Based on worldometers, researchers and demographers come up with different population estimates, allowing individuals and organizations to make appropriate decisions regarding the numbers of their family and friends.
