RESUMO
The challenges posed by climate change/global warming are very alarming, and they have become the focal point of attention for researchers within the global environmental domains. The development of bioenergy can help salvage this situation as a renewable energy source that makes use of recycled waste materials to create useful energy products. This review study found that the development of sustainable bioenergy is environmentally friendly, and it has been proven to be a better means of recycling waste materials into final energy products for sustainable development. The study hereby concluded and recommended that environmental policies concerning the sustainable development of bioenergy should be adopted within the various nations' local laws and the global environment at large, as this will result in adhering strictly to international environmental legal frameworks regulating the prevention and reduction of waste materials. The possible correlation of bioenergy with the Sustainable Development Goals is also highlighted.
RESUMO
The period 2020/2021 was an unprecedented and historic time for industrial, economic, and societal activities all over the world with great challenges to human health, the ecosystems, and other aspects of human endeavors owing to the COVID-19 or SARS-CoV-2 (CV-19) pandemic which is now a topical aspect of research interest. Despite the negative impacts of the CV-19 pandemic, there are also positive reports during the CV-19 pandemic such as the reduction of gas flare, reduction in the burning of fossil fuels from automobile exhaust and a reduction in the other ensuing factors of greenhouse gases emissions (which is one of the major drives for global warming and climate change as well as other environmental effluences). Hence, this brief perspective review study is centered on greenhouse gas (GHG) emission. The study employs a methodical approach to analyze some already available research studies from existing publications and databases on GHG emission using the perception during the CV-19 pandemic. The specific findings from this review show that, from the meteorological perspective, the global response to the catastrophe ensuing from the CV-19 pandemic has a great influence on the reduction of GHGs, the reduction in the burning of fossil fuels from automobiles and industrial devices, and the reduction in the other ensuing factors of GHG emission. Hence, it will not be far from the truth to conclude that there is a possible positive connection between the CV-19 pandemic and GHG emissions. The study has a direct impact on the environment owing to the negative and positive environmental consequences of the CV-19 pandemic. Suggestions and recommendations in the form of future prospects of GHG emission vis-à-vis global warming and climate change are also discussed. Furthermore, suggestions on how to improve food security and agriculture during a pandemic such as the CV-19 outbreak period are highlighted.
