and so forth are problematic but an alarmingly growing threat is of light and noise pollution as it interferes with the natural clock that the organisms (more especially nocturnal) have been accustomed to and consequently altering ecological functioning (Miller 2006; Hölker et al. 2010; Da Silva et al. 2014). Therefore, it is important to acknowledge that not only light pollution is a negative factor in urban habitats; noise pollution also has a significant role in reproductive success of urban dwelling
Large number of the world’s population in recent times tend to live in cities, since it became a standard of living for a large group of people. In the year 2007 half of the world 's population and in 2030 three quarters will be living in urban areas; whereas a great portion of these people are expected to live in slum settlements. The reason behind this increase is due to several factors, including population growth, increased survival and migration. Therefore it should be noted here that the number
We can identify several types of pollution on Earth: water pollution, air pollution and noise pollution. 1.5.1 Water Pollution Earth is the only planet in the solar system blessed with a liquid medium for life to evolve in. We hold the oceans within us, both physically and mentally. So vast are the oceans that they take up almost 71% of the entire surface of the globe (139 million square miles). The ocean basins hold at vast quantity of water, over 285 million cubic miles of water (1185 million cu

sprawl is a city that grows unlimited outward of the development and is unsustainable which it can emerges into leapfrog development. Urban sprawl theory is an effect of cultures and automobile ownership. Urban growth has been inevitable throughout the time and caused population to compete for spaces. It has been estimated the population will be increasing in the coming years. Sustaining the city is important so that the future generations of the city can live in a healthy, social and political stable
1.1 Causes of Environmental Pollution Let us take a look at the causes of environmental pollution: 1.1.1. Residences Residential areas provide their fair share of pollution. To be able to build infrastructure, natural environment has to be demolished in one way or another. Wildlife and plants are driven away and replaced by infrastructure developments. As all this requires the work of industries, construction itself is also a main ingredient of contamination of the environment. Then, when individuals
into three types namely air, water and noise.7 1. Air pollution: Air pollution may be defined as ‘additional harmful materials released into the air which alter its original nature.’ 2. Water pollution: Water is the most abundant and wonderful natural resource which is extremely essential for the survival of all living organisms. However water is polluted with changes in colour, odour, density, taste, turbidity and thermal properties. 3. Noise pollution: Noise pollution is defined as the unwanted and
and the compactness should include the intensification in a wider variety of settlements, including sub-centers and suburbs, which could be connected by efficient transport links. 126.96.36.199 Social Aspect Many authors discuss the social effects of urban sprawl (Hillman, 1996; Kelly-Schwartz et. al., 2004; Duany et. al., 2000).
major cause of pollution. According to census of India 2011, cities accommodate nearly 31.8% of India’s current population and contribute 63% of GDP. Urban areas are expected to house 40% of India’s population and contribute 75% of India’s GDP by 2030 (JNNURM). Industrialization leads to urbanization and poor management of industrial waste and municipal solid waste creates an adverse effect on the environment and human life. Air pollution is the major avoidable cause of disease and death globally (WHO)
recent decades, Vietnam has been entering the modernised and industrialised period, which leads to various changes. Besides some obvious advantages, it has undeniably been confronted with unprecedented environmental problems resulted from air and noise pollution, overpopulation and food and water source contamination. As the result, afforestation, cost-effective waste management system , birth-control and raising public awareness are strongly recommended as some of the most feasible solutions.
