Energy Use and Environmental Impact
Published in B K Bala, Energy Systems Modeling and Policy Analysis, 2022
Pollution means either that a poison or destructive agent (such as crude oil) has been added to the environment or that a nutrient or waste product has been added in concentrations at which the impact is destructive. Environmental degradation, on the other hand, means that something useful has been taken away from the environment or destroyed. Erosion of top-quality agricultural soil, deforestation on a watershed or reduction in a species directly in a community are examples. Pollution may be categorized as air pollution, water pollution, and solid-waste pollution. Emissions of pollutants from energy production and use to air and bodies of water and solid waste emissions are discussed below.

Overpopulation is a towering trouble for our environment. Earth’s population is multiplying swiftly and this speedy progress has set stress on natural resources ensuing environmental degradation. The degree of environmental degradation due to overpopulation differs through various continents of the world. Death rates have decreased as a result of improved medical services, hence, ensued increased life expectancy. Additional inhabitants on Earth necessitate surplus need for food, clothes, and shelter etc. An increasing population infers growing consumption levels. More land is required for agricultural activities as well as more homes to adjust increased number of people. Increasing population means soared extractions from the water bodies for domestic, agricultural, and industrial usages. The largest of these will be agriculture as it is the key nonclimatic driver of environmental degradation plus water level decline. The coming years are going to be prospective for populations to demand more amenities. These stresses in environmental pollution increased waste generation rates, deforestation, loss of biodiversity, destruction of the ecosystems thereby leading to environmental degradation.

Environmental degradation as stipulated by Johnson et al. (1997) refers to the deterioration of the environment by depleting the resources which exist naturally vis-a-vis soil, air, water, ecosystem, as well as other resources that may led to extinction of biodiversity. The environment is degraded when it loses value either as a source of raw material or ecosystem service provider (Etuonovbe, 2009). Since environmental deterioration and high frequencies of poverty go hand in hand, one can hypothesize that the two are related (Penttinen, 2008).

Growing energy demands in the current scenario are going in hand with other devasting environmental effects. Global warming, increased particulate emissions, polluted water bodies, and infertile lands are some representative examples of environmental degradation due to anthropogenic effects. Now, we are in a period where our development should increase using sustainable energy options and, at the same time, have fewer CO2 emissions than fossil fuels. Unfortunately, the percentage of energy catered by conventional fossil fuels is exorbitantly high and well-matured, and it is nearly impossible to make it zero. Hence, to nullify the effects of CO2 already emitted and will be emitted further, CO2 capture and storage technologies become important. The government has already imposed policies on major CO2-emitting sources such as power plants and other industries to capture and sequester CO2.

Coastal aquaculture and estuary ecology are sensitive to climate change and extreme weather events (Van Niekerk et al. 2022). The severe climatic event’s impact is often associated with aquatic animal mortality, environmental degradation, and species structure change. The effect of torrential rainfall and flood water discharge caused by tropical storms may lead to changes in water quality with excessive nutrient loading and disturbance in phytoplankton, zooplankton, and zoobenthos population (Yang et al. 2008). Storms may lead to an increased load of domestic waste pollution from inland. The effect of storms and physical disturbances in coastal ecosystems have drawn increasing attention to seeking an understanding of the mechanisms of the pulse-induced change on community structure, and relevance to the ecosystem resiliency and functions (Duarte et al. 2015). The effect of storms on coastal ecosystems imposes significant stresses on species structure in terms of temporal and spatial change in abundance, biomass, and composition (Greening et al. 2006). Disturbance in nutrients may stimulate plankton production, resulting in spatial variations in phytoplankton, zooplankton, benthos, and fish (Mallin et al. 1999; Peierls et al. 2003; Roman et al. 2005).
A framework for the integration of lean, green and sustainability practices for operation performance in South African SMEs
Published in International Journal of Sustainable Engineering, 2022
GLS manufacturing practices are considered a comprehensive method to simultaneously reduce the negative impact on the environment and produce better standardisation products. Companies need to understand the characteristics and relationships of lean, green, and sustainable implementers to meet the customer’s understanding of environmental regulations and standards. The contributing factors of lean, green, and sustainable elements are modelled and analysed using the SEM approach (Refer to Figure 2). Lean, green, and sustainable enablers make it easier for managers to understand the mutual relationship and linkage between the different enablers. This will be the lead successful Lean, green, and sustainable manufacturing practice program execution. The main implication of this research is to guide industry managers and practitioners by investigating the relationships between various enabling factors, which provide a systematic method to execute and implement the lean, green, and sustainable program. Researchers can generally reproduce similar results for variables and enablers related to their problems by adopting the current approach. Globally, by systematic understanding and implementation of lean green and sustainable programs, society will benefit from reduced environmental degradation in reducing waste and greenhouse gas emissions.
