“…In the past few decades, forestry resources and wildlife species are under stress due to increase in population and its associated pressure. Other reasons behind the deforestation are the increase in industrialization and pollution, which are also linked to human population [3,11,13,17,25,28,32]. Some researchers have shown their concern for the depletion of forestry resources as well as wildlife species and made suggestions for their conservation.…”

The increase in human population has posed several problems for the ecosystem. One of these problems is the decrease in forestry resources, which leads to decline in forest area and thus threaten the survival of wildlife species as the intraspecific competition among the wildlife species increases. Moreover, these wildlife species can also be apprehended easily by poachers and smugglers. This affects the biodiversity across the globe. In this paper, we have proposed and analyzed a nonlinear mathematical model to see the effect of deforestation caused by population and its pressure on wildlife species. The analysis of proposed model reveals that, as the parameters in respect to the increase in population pressure increase, wildlife species decrease. To support analytical findings, we have done numerical simulation.

“…This shows that industrialization affects the biomass of the forest adversely, which in turn may cause harm to the wildlife species and also increase global warming. There are also some research papers (Shukla & Dubey, 1997;Shukla et al, 2011Shukla et al, , 2009 on forest biomass, including the effects of population, pollution, toxicants and industrialization on forest biomass. These articles suggest that human population pressure, toxin release from different industry can destroy the forest biomass and may increase global temperature.…”

In this article, a mathematical model has been formulated by considering forest biomass and global warming as a separate compartment. It is assumed that the forest biomass follow logistic growth in the absence of global warming. It is also assumed that the growth of forest biomass is affected by global warming. It is considered that the density of forest biomass decreases due to natural burning of forests, cut down of forest biomass by human beings and continuous harvesting of forest biomass by human being. It is found that if we can increase the area of forest biomass then the rate of increase of global warming will be reduced. It is also found that if the harvesting rate of forest biomass increases, then global warming will be gradually increased. Finally, some numerical simulation results have been presented.
