1. One can not create a Mitzva out of whole cloth.
2. Not damaging other people’s property is against halacha, and is actionable in Beis Din.
3. Much of the “green” movement is a fraud based on false presumptions such as that the world is overpopulated (which is why most greens are antagonistic to Orthodox Jews), or a mystical belief in a pending catastrophe due to global warming (reality is that it was warmed in Bayis Sheini times, and warmer during Rashi’s time, and climate normally varies – and actually people do better during the warmer periods since crops prefer warmth to frost). Since the “green” movement is not based on Torah, nor on science, some would say that it is Avodah Zarah as being based on faith in something other than Ha-Shem.
