 Green Cities
 What makes a city green? It’s a huge challenge for cities to be earth-friendly. Not 
only do they have lots of people, buildings, traffic, trash, and air pollution, but they also 
consume more than half of the world’s energy.
 Many cities in the world have taken up the challenge to be earth-friendly. Look at 
what some of these cities have done:
 Reykjavik, Iceland, is run entirely on green energy. Its transit system uses hydrogen 
buses and most of its buildings use non-polluting energy sources like geothermal and 
hydroelectricity.
 Malmo and Stockholm in Sweden are noted for their green spaces and parks and for 
successfully cleaning up their water and air.
 Portland, Oregon, was one of the first American cities to focus on earth-friendly 
transit with light-rail and bike paths to encourage people to leave their cars at home.
 Curitiba, Brazil, uses unique green methods for maintenance. Their grass parks are 
trimmed by sheep!
