In the article “Study shows urbanization impact on biodiversity” BBC Science and environment reporter Mark Kinver reveals several social studies results to illustrate how urbanism causes cities loss biodiversity. It makes our society be aware of the importance of ecological sustainability and the possible improvements in modern urbanism. In the report, a research scientist from Rutgers University, Myla Anderson, claims that urban cities tended to overlook the preservation of “unique biotic heritage”. As a result, many local species such as birds and plants were disappeared. Comparing with those underdeveloped regions, urban cities have relatively low “biotic heritage” rate. Calling the very few Green spaces left in urban areas as the “important refuge”, Anderson then points out that city planner has to take considerations into account to maintain the balance between urban biodiversity and rapidly developed ...view middle of the document...
Ecosystem service such as water quality control and flood protection are the good cut-in points city planner could think about.
In 1923, Sociologist E.W Burgess created the concentric zone model to sector a city in five pieces and set its economic function into five different models. From the structural designing, the limited spaces were destined to have less opportunity in further expansion. However, OBD are now being questioned for loosing biodiversity. Instead of critics, we can see the demand was obvious. People expect to see a new styled urbanization, or let’s just call it “Urban Enrichment”.
On one side, as the main theorem Rubenstein introduced in “Human Geography”, “Central business district” (CBD) refers to the area that contains the settlements with longest history. In both developed and developing countries, the CBDs are the city landmark that attracts times of businesses, international tourism and public service. It contributes high-marginal revenue to the region. Because of the many clustered department stores, public infrastructures and emotional dependency, people set very high expectation to CBD and treat it as the greatest image of a city. For sure, biodiversity is crucial to ecologies to study with. On the other side, as a possible solution, remodeling the CBD structure requires a big scaled planning. Whether the region will eventually become more economic efficient or environmental better-off, the progress need different social groups to pay more attentions to the possible reform of urbanism and begin to make possible changes in our everyday life. For example, raising standard of green architecture and artistic urban plantation improvement would both be very helpful.
In short, we should expect to see that global environmentalists, socialists and city planners soon work together to recreate the CBD in the next few years. It is not a simple question but require a lot of researches and cooperation locally and internationally. If one new successful model can be found, then the question of how to preserve our “unique biotic heritage” will then becomes the new strategy of urban enrichment we are looking for.
