It is impossible to overstate the value of effective fisheries sector management in a society like Nigeria. This will guarantee enough food at affordable prices and a source of social and economic advancement for the populace. Living ocean resources are in danger of becoming extinct due to the high harvesting rates. Over time, the legal measures enacted to safeguard the maritime environment and actions taken by the institutions tasked with upholding them have been shown to be insufficient and ineffectual. In this study, the management of fisheries and marine life resources and the difficulties it faces was evaluated using both primary and secondary sources of information. This was geared toward creating a framework that guarantees the sustainable conservation of marine living resources in Nigeria, particularly fisheries. According to the study, fisheries must be conserved if they are to remain productive for a very long time. It describes the opportunities and difficulties facing the Nigerian fishing regime and suggests ways to achieve long-term preservation of the fishery resources in the Nigerian marine environment.

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.
