Air Pollution in Mexico City
Title: Air Pollution in Mexico City
General information about the problem: As the vehicle population reached more than 700 million, numerous cities experiencing rapid industrialization started to suffer from air pollution. Some of them reduced the air pollution level; however there are still some that are considered to be the most polluted cities in the world. Introduction of the problem: One of them is Mexico City. According to Forbes, Mexican capital is one of the five dirtiest cities of the world. Industrial growth of the city, population boom, which grew from 3 million in 1950 to 20 million today, and the proliferation of vehicles in the city contributed to the Mexico City’s current air quality. Narrowing down the problem: However, with the transportation proliferation contributing to about half of the city's total emissions, several solutions have to be considered in order to reduce the air pollution in the city. Thesis statement: The government should practice legal regulations and favor the evolvement of environmentally friendly technology and fuel in order to reduce the air pollution level in Mexico City. II. Background
A. Identify the problem/ show that the problem exists: People suffer from various diseases and the environment is being damaged (research). B. What caused the problem: Air pollution is mainly caused by vehicles. C. The effects of the problem: Air pollution can have serious consequences for the human health as well as severely damage the ecosystem. III. Solution 1
Topic sentence: One of the possible solutions is to continue to enforce legal regulations concerning air pollution prevention. Give grounds to the proposed solution (e.g. this problem has been solved somewhere else; experts suggest this solution…): The air pollution has been noticeably decreased due to legal regulations and governmental programs like PIICA, PROAIRE and PORAIRE III Describe your solution: Diminish taxis
• As taxis are diminished, less harmful gas emissions are produced Disadvantages:
• Taxis are convenient
• Taxi driver as a job
Topic sentence: Another possible solution is to pass a law on telecommuting. Give grounds to the proposed solution (e.g. this problem has been solved somewhere else; experts suggest this solution…): Less gas emissions on telecommuting days (research) Describe your solution: Pass a law on telecommuting
• Can be implemented now, as it does not require any expanded planning, design and construction; • Is relatively inexpensive to implement;
• Expands personal choices rather than restricting them, by offering them more flexibility in work and lifestyle. Disadvantages:
• May incite legal issues between organization and employers • Lack of interaction with co-workers
• Not all jobs are suitable for telecommuting
Topic sentence: The last, but not the least possible solution is to replace gasoline usage in the city with hydrogen fuel. Give grounds to the proposed solution (e.g. this problem has been solved somewhere else; experts suggest this solution…): The research indicates that usage of hydrogen fuel will definitely decrease the air pollution level. Describe your solution: Hydrogen should replace gasoline. Advantages:
• Reduction in air pollution due to zero emissions
• Hydrogen is abundant (renewable source)
• Hydrogen is expensive to produce
• Hydrogen refueling stations construction require big amounts of money VI. Conclusion-Recommendation:
Mexico City is often said to be the most polluted city in the world. It certainly does pose serious environmental threats to its own survival as a city, but it affects regional and global air quality levels as well. Therefore,...
