Barnaby Bear starts his sightseeing tour of Mexico City by going to the top of the Latin American Tower. From here he can see that the city goes on for miles and is surrounded by mountains and volcanoes. One of the volcanoes is known as 'Smoking Mountain'. There is a haze across the city which is caused by pollution. Pollution is a big problem in Mexico City. The city lies in a bowl-shaped valley surrounded by high mountains. Approximately five million cars travel in the city every day and the exhaust fumes get trapped by the mountains. Green taxis now use unleaded fuel. People must have emissions from their cars checked and leave their cars at home one or two days per week.

Students could explore the issues of pollution in Mexico city. Why is pollution such a big issue in Mexico, and what are the Mexican people doing to try to fix it? Can students make any other suggestions to help reduce pollution? Students could write a letter from Barnaby to a friend back home in Britain, sharing what he has learned from his trip to Mexico.

Students could also consider how Mexicans have adapted to living with the constant threat of earthquakes and volcanic eruptions. What sort of precautions would you need to take? Students could be given information sources and use these to create safety leaflets entitled, ‘How To survive An Earthquake’ or ‘How To Survive A Volcanic Eruption’.
