Design a tryptich about Granollers as a sustainable city. The tryptich
should have different texts. These should explain the different aspects
of the city ( the modern city, the city and its people,etc. ) and the resources
that are used to recycle the rubbish, control the pollution, take profit
of the natural energies, etc. The tryptich is published by the City Council
of Granollers so that the tourists can be aware of all that.
The texts should be written in English and should include photographs
or drawings.
