abstract:The Green Key is an international eco-label tourism facility that aims to contribute to the prevention of climate change and to sustainable tourism by awards and promoting good initiatives. The Green Key aims to change the practices and behaviors of actors, guests, enterprises, authorities, and local communities, and its desire is to involve them in increasing their responsibility toward their own environment.
Whenever the pigeons pecked the greenkey, the red key would go away for a while, meaning that the pigeons would no longer be tempted to peck it to get food.
