The defective environmental changes caused by climate change have a drastic harmful effect on natural habitats and species. This is concerning the fact that there are signs that the increase in the intensity of temperature often has (caused by human activities) an effect on biodiversity. However, the threat posed by climate change to biodiversity is expected to increase, given the harmful human activities. The scientist has identified that if the present rates of global warming continue by 2030, it will result in a significant detrimental impact on biodiversity. In this regard, this study adopts a doctrinal method of study in examining the current causes of climate change, the effect of climate change on biodiversity, and several global legal frameworks concerning the preservation and conservation of biodiversity. The study also detailed the lacuna inherent in the conservation and preservation of biodiversity, and possible legal and scientific method for revamping biodiversity. The study further concluded and recommended that adopting this possible solution it will curtail harmful human activities that often cause climate change that negatively affect biodiversity.
