Environmental sustainability is about the quality of the environment. It relates to three dimensions. These dimensions are ecosystems, humans and energy. The environment will be sustainable if we consider it to be a balance between the three. If we do not consider the environment in this way, then environmental sustainability is threatened. To preserve the environment, we need to know what impacts we have upon it.
One way of preserving the environment is through effective management of water management. This is achieved by reducing the use of non-recycled resources such as water, electricity, and fuels. Another approach to environmental sustainability is through proper utilization of renewable sources of energy such as wind and solar power. A third perspective on sustainability concerns biofuels such as ethanol.
The use of biofuels in our cars helps reduce our dependence on oil, but at the same time, environmental problems associated with the use of gasoline to make it an impractical fuel source. The demand for an alternative to gasoline is therefore needed to prevent the grave environmental issues related to the use of fossil fuels. The objective of environmental sustainability is therefore to use economic efficiency and ecological efficiency in the same context to promote sustainable development. Thus, an environmental impact is considered to be sustainable development when it decreases the total ecological impact of the processes involved in the generation of the end product.
The processes involved in the generation of the end product also have to be in accordance with the ecological quality of the environment. This aspect has been recognized by many since the inception of the modern economy. For example, arable land has been used for agricultural purposes which has led to depletion of the natural resources of the soil. If the use of pesticides is further encouraged, the soil will become even more depleted and there will be a need for better soil management and protection so that the soil can regenerate its natural resources. Thus, the use of biofuels as an alternative to gasoline is necessary for the preservation of the soil and the future generations.
However, life cycle impact assessment and environmental sustainability do not go hand in hand. One of the challenges in life cycle impact assessment is the identification of the effects caused by any given activity at any given point in time. Biofuels are compatible with the existing life cycles in the sense that they do not cause any change in the productivity of the land. Also, biofuels emit less CO2 than the gasoline emissions. In fact, the production of biofuel makes available to us more green energy than the conventional sources that we are currently using.
In addition to these benefits, the adoption of renewable resources would increase economic growth because of the increased availability of energy and the employment that could be generated because of the increase in the demand for employment. This is because of the increased value of the land and the natural resources. Another advantage is that the process of naturalization of the bio-energy does not result in the conversion of the land into something else. This is unlike the process of naturalization, which can sometimes have an adverse impact on the land, the natural resources and the people involved.
On the other hand, the environmental sustainability involves the management of the resources after the use and the exhaustion of them. Natural environmental sustainability takes into account the damage to the environment caused by a particular activity. It also takes into consideration the costs borne by society as a whole, through lost economic growth, through degradation of the soil and through pollution of the air, water and land. These damages can be avoided if and only if the ecological sustainability is maintained. The use of renewable resources and the reduction in the use of conventional sources can significantly reduce the amount of damage done to the environment.
On the other hand, the ecological sustainability does not have a consideration with the damages caused to the human health and the economy due to climate change and global warming. It focuses only on the preservation and enhancement of the ecological resources. Its main focus is on protecting the biological diversity and its ecosystems. In this case, the main focus is directed towards the development of the human population into a more sustainable state. Through the adaptation of the environment to accommodate different climatic changes in the availability of the natural resources, the north sea could be considered as one of the world’s greenest areas.
