The speech by Professor Mario Molina, at the Science Center in Cambridge was intriguing and up-to-date. Professor Molina is a well-known scientist, born in Mexico City. Molina is not only a remarkable professor, but also he won the Nobel Prize in Chemistry in 1995. Not to mention, Molina was on the Committee of Advisors in Science and Technology for both President Obama and President Clinton.
Molina talked about current issues in severely polluted cities, such as Mexico City and Beijing China. He focused on Mexico City primarily, because that is where he has centered most of his studies. He said that one of the main causes for the polluted air in Mexico City is the excessive amount of cars. Molina said “there are over 5.5 million cars in Mexico City.” Molina recommended, “By emphasizing the use of public transportation, the people of Mexico City can decrease the amount of fuel they use.”
Molina emphasized that communication is key when dealing with an issue that is so socially driven. Molina repeated it is essential to “communicate with the people that there is a problem and then there will be progress.” For example to deal with air pollution, Molina says a good solution is “to own a garden and to use it.”
Mike Sanchez, a man from the Harvard School of Public Health, who used to be a Manufactory Manager in China, asked the question “What practices would you advise to the Chinese government to help them start reducing pollution in Beijing? Should we buy fewer cars in Beijing? Do you think they should remove sulfur from power plants? What should we do?” Molina responded with “Well we need a little bit more science to know the answer to this question. Make sure there is public transportation and encourage people to use it to go to work. We don’t have the answers, but we know there are certain emission levels that have to be reduced.”
