Recommended: Abstract on water pollution

Urbanization is occurring at a very fast pace in the current world. A lot of developments and inventions are being realized in order to fulfill the needs of the growing populations. However, in the process of urbanization either directly or indirectly, a lot of damages have been done to the surrounding environment. Pollution and humans are quite correlated to each other. According to Holdgate (1979), activities carried out by human to the environment that affect the organism and ecosystem are called pollution. In general, pollution can be categorized into four major categories such as water, air, soil, and noise (refer to Figure 1 in Appendix). The first type of pollution is water. According to Goel (2006), water pollution can be defined as a group of factors causing aesthetic or negative effects on the water consumers. It occurs when there are regular changes in terms of the content, condition and color of the water …show more content…

Noise pollution means emissions of annoying sound from traffic and industrial and recreational infrastructures (Urban & Máca, 2013). Most of the sources of this pollution come from outside of the home such as transportation systems, including noise from vehicles, aircraft and train. Not only that, sources of noise pollution in and around the house are noisy sound like a car alarm, siren emergency services, construction machineries, barking dogs, electrical equipment, motorized appliances, and loud audio entertainment systems. Sound effects are related to health and natural behavior like ear buzzing or 'tinnitus' which can cause a person to experience memory problems, severe depression and panic attacks that cannot be overlooked. There are various strategies to prevent noise pollution. For example, road noise can be reduced by using noise barriers, limiting vehicle speed, road surface texture change, limiting the weight of the vehicle, using a smoothing traffic control traffic flow to reduce

Dennis B. Blanton describes how causing more and more freshwater is becoming brackish causing fresh water to become scarce. To be able to get drinking water, the colonists dug wells across the land. However, the wells became vulnerable to drought and salt water intrusion. He also talks about how the transition affects the water. Due to the saltwater transition, and the filth within the water, the water was the reason for many diseases.

Urbanization, or the growth of cities, erupted during the Industrial Revolution. Cities were a place of work, innovation, and technology. Over the course of fifty years (1850-1900) more and more people moved to the cities, which caused more and more problems in them. With these problems came solutions, and those solutions led to change. These changes could be good like movements to get cleaner water or having plumbing.

Osmosis is the diffusion of water through a membrane from an area of high contraction to an area of low concentration. Osmosis happens in three different environments. Osmosis is like diffusion in it requiring no energy. Osmosis can happen in three different types of environments; Hypertonic, Isotonic and Hypotonic. If osmosis were to

A shock city is the urban place that represents a massive and rapid changes in social, economic, and cultural life (urbanization) due to many factors, including new models of transportation such as railroads, industrialization, and other factors. The first city that was considered the “shock city” was actually Manchester, England. It grew very quickly, and it was the world’s first industrialized city and the home of the cotton industry, cottonopolis - a metropolis centered on cotton trading. Same as Manchester, Chicago was also the “shock city” of North America because of its rapid growth. Both cities were industrial cities, Chicago rose from a struggling village sunk in the middle of a grassland creek to a metropolis city.

2.1 Urbanization and river water quality Due to movement of people from rural to urban areas, physical growth of the urban areas occurs, which ultimately leads to the urbanization, Over the past several years, river systems have always been extensively altered to meet various human demands, which led to them becoming the most intensively influenced ecosystems by human activities on the Earth (Nilsson, et al., 2005 )]. ‘’Among these human activities, the influence of urbanization on river systems was the most significant, and 60% of river systems were changed profoundly because of urbanization in the world’’ as cited by (Nilsson, et al., 2005 ) Recently, a number of studies have been done to understand the effects of urbanization on river water quality. The study manifested on Pearl River Delta Economic Zone is in China, that there is a positive correlation between the rapidity of urbanization and the pollution levels of urban river water.

CHAPTER 1 1. INTRODUCTION The air we respire contains mixture of natural and man-made chemical, physical and biological elements that modifies ambient air quality. Among all air pollutants, the most threatening for human health include particulate matter and gaseous pollutants such as carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide (WHO). The movement of people into urban areas and the growth of industry within these areas has carried more people into contact with air pollution than any other time in recent memory.

Pollution is the introduction or release of substances or energy that decrease the quality of the marine environment. Many pollutants are toxic of harmful to marine life (Castro and Huber, 2010). South Africa is known around the world for being one of the most diverse marine environment in the world, with 83% of the known fish families residing in South Africa (Van der Elst, 2007). There are also many marine species that are endemic to South Africa, which means they are only found in South Africa. Almost 30% of the South African population lives on the coastline (Taljaard et al. 2006), which has led to the urbanization of the coastlines and which then led to the industrialization of these areas.

Another important issue that even students get late to their school and everything will not be in time. Congestion always happens when people go and come from work so employs play a big part in congestion and it happens especially in big cities as the streets are big and people have their own cars not like towns or villages. In big cities, people prefer to use more their own private cars than using public transport but in towns they prefer the public transport. So, in big cities there will always be traffic jam as there are so many private cars in the street. When cars are banned then the traffic jam would disappear and people will be able to arrive in time and won’t affect

There are many problems that threatens society and one problem in particular, air pollution is a problem that threatens everyone. Air pollution is the contamination of air with pollutants that are harmful to humans, animals, and the environment. It began to be a problem when humans discovered the uses of fire and then the amount of air pollution exponentially grew after the industrial revolution, and is still a problem even today. The largest causes of air pollution are from human activities such as burning of fossil fuels and gas emissions from manufacturing plants. There are ways that ordinary people can help contribute to prevent air pollution and or else face the dangerous consequences of polluted air.

LITERATURE REVIEW What is water pollution? As the country is becoming more and more populated, the demands for social services have increased significantly. This has led to an increase of the pollution in many developing towns such as Ga-kgapane. The most disturbing and problematic forms of pollution in Ga-kgapane is the pollution of the natural streams. Water pollution is when there is a build of one or more substances in water to such an extent that it causes problems for animals or plants.
