Introduction

The urban sprawl is advancing at an accelerated speed through the global motorization. But in the meantime, the development of motorization brings about many problems which involve the ecological and social aspect. Therefore, the business groups recommend the approach of ecological modernisation to deal with these problems.  

This essay will analyses some possible causes of these problems and argues that the approach can not resolve these problems arise from motorized urban sprawl.

The motorized urban sprawl brings about higher level greenhouse effect through discharges of greenhouse gases. It is obvious that compact urban development, the growth of new cities and sustained movement continue to put heavy demands on urban transport systems. Meanwhile, new buildings have mushroomed on the periphery of the town. Therefore, urban expansion leads to more fuel utilize in transportation and capacious homes on the metropolitan fringe. Furthermore, the mass production of vehicle led to mass suburbanization and to an urban sprawl in the 20th century (Martin, g.2007.para.5). This human activity is the main root cause of greenhouse-gas emissions. The international business organisations have attempted to combat greenhouse effect with technical innovation. They begin focus on the long period energy solutions which include cleaner fuels and alternative energy sources (Gonzalez, G.A .2005.para14).

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.
