This paper studies the impact of climate change and habitat loss on extinction threshold of species. When global biodiversity is gradually being altered by human activities, species respond differently to such alterations in response to habitat destruction and habitation fragmentation. This alteration of global biodiversity is accounted for to be the effect of climate change which is anthropogenic in origin, as we commonly call it global warming. This global warming is not only bringing about alterations in climatic patterns, but such drastic changes are reflected in species behaviour as well, wherein, some species are either adapting to such changes, or becoming extinct. The study was done by modelling such a system which would impose stress effect on the species and determine their extinction or survival thresholds. The results indicate that the model is effectual, and it is possible, with data availability, to apply the model to compute changes in extinction thresholds or compute the effects what climate change have on such species.
