However, there are two shortcomings in the solutions to greenhouse effect. Firstly, nuclear energy is a kind of cleaner fuels advocated by the business group. But the energy also has remarkable environmental damages in the process of the production and the disposal. Furthermore, the proliferation of nuclear energy may results in the permanent environmental damage. Accordingly, the cleaner energy of present technology only transfers the problem to other ecosystem. Secondly, the alternative energy is not obtainable yet. For example, the hydrogen would be a potential replacement for energy, but there is no discernible progress in the development of hydrogen.
Motorized urban sprawl is a threat to public space through increased consumption in motorization’s privatized. Motorization plays a major role in encroaching public space. For instance, the scarcity of pedestrian traffic in motorized urban sprawl suggests a private social life enclosed within vehicles and homes (Martin, g.2007.para.10). The ascendency of the private vehicle results in serious transport injustice in some social groups (Bullard and Johnson 1997, citied in Martin, g.2007.para.10). Meanwhile, the staggering advancement of motorization is attended by The urban infrastructure stretched,because urban put a strain on the public space . A principal instance of the social impacts of motorization is china. In the face of the threat, measures were taken to resist motorization in china by the authority. The adoption of modernization ecological in china has been renamed ‘sustainable growth’ by the Chinese government. The authority endeavors to facilitate traffic flow through technological solutions. They concentrate on exploitation land by evaluating environmental effects and minimizing dependence on vehicle.
But there are two shortcomings in the solutions to the social problems. Firstly, although relatively clean and energy-efficient vehicle technology in china is available (Martin, g.2007.para.21), this technology doesn’t restrict the increased miles of travel which is connected with modernisation of urban sprawl. Secondly, from another point of view, the conception of ‘sustainable growth’ is not possible in reality, because development needs the depletion of natural and manpower capital at great costs to the world. It is hard to keep a balance between protection and consumption in natural resources.
Conclusion
This paper has argued that there are several problems caused by motorization in cities. The international business groups presume upon that ecological modernization is possible for society to advance both economically and socially, in the meantime preserve the environment. They tend to further or the scientific and technological progress but not attempt to limit to urban sprawl. In term of the degradation of public space, there are few or no technological interference available for the problems of land transition. The approach of ecological modernization would leave urban to sprawl further. We should realize that many technological developments are presently attainable but not far and wide utilized (Fisher and Freudenberg, 2001). Meanwhile, technological advances can not alone achieve the targets which are resource preservation and environmental protection. Overall, I am convinced that ecological modernization may fail to combat the problems under these circumstances and inevitably result in environmental degradation.
