How Does A Sustainable City Affect The Environment? (Research Paper Sample)
A sustainable city is a city which can power itself with renewable sources of energy and produce the smallest pollution. Generally, it should be created with the ideal balance of social, economic, environmental influence factors, to fit the existing population. The cities are necessary to have their own power station in order to reuse the natural resource. Many kinds of resources can be recycled and reused. There are non-renewable resources, such as coal mine. Technologies can increase its efficiency, which is using less amount of stuff to get more energy. By increasing the use of ration of a limited resource, it can use power more effectively. Also, with the increasing of the population, society will need more basic resource and power to support the overall population.
The recent technologies allow energy transformation to create pollution However, the pollution is supposed to be much lower in order to design a sustainable city. People start to make air pollution a hundred years ago. Global manufactory center changed from Europe to Asia as time passed. Government changes the locations from one to another as they would like to fix the seeming problems. More importantly, the balance between society, economy, and environment need to be maintained in an ideal sustainable city. The city itself needs to have an internal balance with society and the economy. Government plays a significant role inside this problem, which they may create policies, bills, and laws to minimize or ignore the pollution that comes from human necessary energy transformation. A sustainable city needs to be designed to become an environmentally friendly city. Pursuing natural balance is the main purpose of the city. Individual and social impacts are general problems when facing environmental issues. Over a long time period, humankind is kept finding metals for trading and discovering non-renewable resources to make a grand amount of energy which is necessary for living human. It is not beneficial for either the atmosphere and the earth environment.
The sustainable city will be a popular tendency in the future of human society. The nations and governments tried to limit and control this problem through policies and laws. However, they often suffer from the balance between human rights and the environment. With the development of society, people start to be aware of what human activities can make a severe influence on the overall environment and other species. It helps the recent global situation of fixing environmental problems. Later, it is beneficial for creating sustainable cities.
How does a sustainable city affect the environment?
It is estimated that 50% of the global population now live in cities. With this migration into large urban centers, the difficulty of meeting the needs of significant number of people becomes an ever-increasing problem. Overpopulation, excessive consumption, pollution, and depletion of resources have presented environmental and health challenges in major cities. The need has never been greater to find solutions and reimagine urban landscapes (oxfam.org np). In 1994, the Aalborg Charter was created for sustainable cities and towns, and since then cities around the world have been leading the way in innovative and integrated approaches to sustainable living. The charter calls for a commitment to urban management, sustainable local economies, responsible consumption and demands legal action for violations of health, social equity, and justice.
The world is urbanizing at a rapid pace. By 2050, more than 2 billion additional people will be living in cities (United Nations np). Furthermore, the vast majority of this growth will be concentrated in developing countries, with nearly 90% of the increase from cities in Africa and Asia (Global Environment Facility np). Therefore, cities remain the best place to start addressing huge trends driving global environmental degradation, including urbanization, a rising middle class, and growth in population.
As engines of economic growth, cities generate approximately 80% of the global gross domestic product (GDP). Additionally, they consume over two-thirds of the world's energy supply and produce 70% of greenhouse gases (Global Environment Facility np). Cities are also uniquely vulnerable to rising ocean levels because of climate change, with 14 of the world's 19 largest cities being located in port areas.
If well managed, solid, resilient, inclusive and resource-efficient cities could become drivers of the green economy that depends of environmental friendly resources such as green energy. This will contribute to both local livability and global public goods. Conversely, poor management leads to urban areas with degraded land, strained ecosystems, and essential infrastructure services, increased levels of pollution, and increased size of vulnerable populations (Global Environment Facility np).
The population impact approach becomes largely irrelevant for understanding cities. It does alert us to our natural base, but it can be used to generate many rather ridiculous policy implications, from humans shifting to the ruralization of cities (Newman 276). Nonetheless, it becomes essential to seek a more expansive way of understanding cities. Population impact is largely a devastating concept since it asserts that the primary task of urban policy is to be against humans. There is little room to suggest how a city can manage its population growth, or even see it as a positive force on the impact of humans in the world.
Thus, population impact is not only difficult, but of uncertain value, if the goal is to reduce the urban local or global effect. The primary issue around the growth of cities is ensuring that such growth is used to solve problems (Newman 277). Global and regional environmental problems are real and are significantly contributed to by cities, but stopping urban population growth is not a solution to such issues, and might even make them worse by distracting from the need to restructure and change how individuals live in cities.
A more refined analysis of the impact of cities has been developed into a methodology that can calculate a city's Ecological Footprint, based on an ecological understanding of how a city extracts food, water, energy, and land from...
