Urban areas are quite warmer than the rural counterpart, the natural ecosystems are being replaced by buildings and other structures. There is significant temperature differences between city centers and their surrounding countryside and surface temperatures can be much greater in high density suburbs compared to low-density suburbs; the reason…

1. Thinking about your own life using Bronfenbrenner’s ecological model, can you draw a picture of the various layers context in which you grew up? Answer: Bronfenbrenner’s ecological model: child, microsystem, mesosystem, exosystemic, marcosystems, the inter part the microsystem is concentrates on the family and the institution the child may interact with on a daily basis.

1.1 Case Study Sumatera has one of the largest rain forests in Indonesia as well as in South East Asia. Sumatera Forest basically has peat soil type that caused easier to burn. Estimated between 7.3 to 9.7 hectares are covered by peat lands or roughly a quarter of the entire area of peat lands in the tropics (Hisyam, Damanik, Anwar, 1984). Sumatera Forest Fires are the one of the serious problem in Indonesia. It happened almost every year. However, some of the biggest were happening in 1982,…

China and the Games The Olympic Games have stood the test of time. Over the centuries, countries around the world hope to win the bid to get to have the chance to host the Olympic Games. This chance is a perfect opportunity to show off whatever host nations offer. The Games put a country on international display to host thousands of athletes from around the world.

Most of the emissions are released from the man-made sources as compared to the natural sources. “Burning of fossil fuels in industries and transport sector, industrialization and urbanization have led to increase in concentrations of gaseous and particulate pollutants in the atmosphere leading to air pollution” (Singh & Agrawal, 2008, 15). When these pollutants are released from their sources, they become caught up in prevailing winds and can travel long distances to other regions or locations…

As a “modern day Babylon,” named by Jonathon West, a journalist for Management Today, Dubai has grown at an unprecedented rate since the turn of the century. With a population of 183,187 in 1975, this number has increased tenfold in thirty years – a rate never before seen. Not only has population increased, but Samer Bagaeen wrote in International Planning Studies that its income from oil has increased by as much as five times since 2006, bringing in $305 billion. Using this instant source of…

Formula 1 cars emit approximately 2,400 gms of carbon dioxide (CO2) per mile (almost nine times as much as an ordinary new car today), that equates to 17 tonnes of CO2 per season. When air travel is included, this figure rises to 54 tonnes of CO2 per driver per annum. These figures point towards a startling discovery about how unsustainable motorsports are and how the World has turned a blind eye to an industry that functions at its own whims and fancies. But all hope is not lost yet, there are…

CHAPTER 1 INTRODUCTION 1.1 BACKGROUND The catalytic converter was invented by Eugene Houdry, a French mechanical engineer and skilled in catalytic oil refining who lived in the United States around 1950. The invention of catalytic converter has a major role in controlling harmful emissions. When the paper of smog in Los Angeles was published, Houdry became anxious about the role of smoke stack and automobile exhaust in air pollution and established a company, Oxy-Catalyst. Houdry primary…
