The number of synthetic fields is in progress, but many people are confronting this issue. People like Patrick Barnard from http://www.savewestmountpark.com and Guive Mirfendereski from http://www.synturf.org are constantly publishing news about this specific hot topic.
The westmounter group Savethepark! was particularly strong when the Westmount council announced the decision to construct a new synthetic field in Westmount Park. About this theme see the article : "grass warfare in Westmount"
Camilo Pérez Arrau from UQAM collaborated with Savethepark! by sharing his master work on satellite images. These coloured pictures showed here (PDF, 1017 Kb) helped to show people how hot the synthetic fields could be.
