World Population Day is an annual event on July 11 to raise people's awareness on various population issues. It was instituted in 1989 as an outgrowth of the day of five billion, reported on July 11, 1987("World"). Over 20 years passed, the importance of the problem of human overpopulation has been and continues to be a matter of debate. According to news from National Geographic, a photographer, Russell Moore, presents a photo of the population and states that human population has never stopped increasing since 1987. There are over 7 billion human populations on the earth now ("World Population"). Some spectrum supporters urge that overpopulation is not actually a problem, while proponents on the other side of the spectrum assert that overpopulation is a major crisis and that humanity is poised on the edge of destruction unless people find ways to reduce population growth. Either viewpoint is extreme. In some places around the globe, overpopulation is indeed a serious concern. Yet the world is interconnected, therefore since some areas are experiencing a problem with population growth, eventually overpopulation will affect the entire human family around the world. Fortunately, this situation has not been too dire to control. It is possible to effectively combat overpopulation through a combination of education, government programs and the proper distribution of resources. .
In order to solve the population issue better, it is necessary to primarily understand the underlying causes that have contributed to the population growing too large, and there are three major factors that have supported the contribution are advancement in medical technology, advancement in agricultural technology, and religious and cultural belief systems. First, advancement in medical might assist the population to become more and more because this important advancement has helped to both reduce the mortality rate for the older individuals and infants, and to extend life span.
