Here in Mexico City, there is such a vivid culture and life that surrounds one of the world's biggest cities. In addition to the rich heritage and history that can be found here, there is also a thriving economy. Mexico city is the economic engine of Mexico and more than half of the country's industrial output is produced here in the city. Important industries include textiles, chemicals, furniture, plastics, and metals. Also important is the food and tourism industries that thrive here in Mexico City and bring in millions of dollars into the economy. Also important to Mexico and its population is the informal economy. This includes the thousands of street vendors that sell anything from food and beverages to electronic appliances. These street vendors prove to be a hindrance to other business owner in the city because they can take away from their profit by selling less expensive and similar products on the streets. However, not allowing these vendors to sell items in the streets would cause many to be unemployed and would create even more poverty than there already is in Mexico City. These vendors help to create part of the unique atmosphere in Mexico City and help to increase the standard of living of many by keeping able-bodied workers employed.

San Francisco is an amazing city that I have actually had the chance to go to myself when I was younger. There is so much to do in this city, from seeing the Golden Gate Bridge, to taking a trolley ride down the slanted streets, to visiting Chinatown. This city is actually very safe and a pleasant city to visit as long as you stay in the right areas of town. Also, driving may be a little difficult for some people since the streets in San Francisco can be positioned at an angle or very curvy at some spots in the city, so it is best to take caution while driving. If you do not wish to drive, there is an excellent public transportation system set up in San Fransisco that is very tourist friendly. Fog in San Francisco can also be a safety issue if you come unprepared, so pay attention to the weather conditions before you leave to explore the city and pack accordingly. San Francisco also has a very well developed public health system designed to fit a variety of health conditions and diseases. Overall, San Francisco is a very safe and healthy city to live in, with an abundant amount of culture.

Reykjavik, Iceland

I am here in Reykjavik, Iceland that is called by many the greenest city in the world. It has made many efforts to remove itself entirely from fossil fuels, and it has greatly invested in new renewable energy resources. These resources include hydrogen and geothermal power. This city uses this renewable energy source to heat many of their homes and businesses all throughout the area. In fact, 89 percent of homes in Iceland are heated by geothermal power and over 54 percent of the primary energy used in Iceland comes from geothermal sources. Hydrogen is also a major renewable resource used in this city. There is a large effort to reduce the amount of fossil-fuel burning cars and replace them with cars that run on renewable energy. In 2003, the first public hydrogen station was opened in Reykjavik to serve the growing number of hydrogen cars. The city has also put into place a public transportation system of hydrogen buses. These buses use only hydrogen as their fuel source, so their only emission is water. Also, students can ride these buses for free to encourage the use of renewable energy. Other initiatives to promote green energy are the increased number of bicycle and walking paths, the strengthening of the recycling program, and free parking to environmentally friendly vehicles. These and many other programs are making Reykjavik an even greener city.
