Abstract: During the present study, a review was carried out on changes in the behavior and population growth of rats providing favorable conditions in limited space. Overpopulation suppresses the carrying capacity of a particular geographical area. Overpopulation has become one of the most threatening global issues that impact the world adversely. Every year it grows by 1.2%. Scientists are fascinated about the fate of the human population and the behavioral influence among the population due to limited living space. Many Biologists and Ethologists perform various experiments taking rat population as model and consider it relevant to human population. Rats are social animals and have very similar societies like humans. Scientists can relate many behavioral and social similarities between human and rats. All the favorable conditions like bedding for nest, food and water in unlimited amount was provided to an inbuilt closed enclosure of rats but the only restriction was limited space. Population of rats increased exploitationly due to these conditions and got more catastrophic results throughout the study of over-population in the past years. Results are in the form of their behavioral breakdown which can be seen in the form of parental care and social fabrics. These results can predict the fate of the growing human population. High populated conditions concern Health-related issues and depressingly predict pro-reproductive attitude to have offspring in addition to optimistically predicted anti-reproductive attitudes above the influence of age, gender, and spiritual status.

I. Introduction

Man advances in their activities in cultural, social, economic and technology to enhance their livelihood. On behalf of these, humans have four distinctive features: (I) Humans have long lifespan, (II) Slightly long time period of immature dependency, (III) Ability to reproduce in post-reproductive period and (IV) Male support and protect females and their infants (Kaplan, 1997; Kaplan et al., 1999). The death rate among human is decreasing due to present day medical services and high quality food resources.
