Summary Introduction
To determine: The fate of the human
Introduction: The human population is regulated by different density-dependent or independent factors. The population regulated by the density-dependent factors leads to a decrease in birth rate and an increase in the death rates. In contrast, on the other side, when density-independent factors regulate the population, then it may lead to a decrease or increase in both the rates.
