I am not politically savvy, and I do not wish to belong to a lot of "activists" groups. however, I do not see why I would not participate in helping raise the awareness of our human responsibility towards the rest of the creation. It is what the third blessing is all about.
My personal effort in protecting the environment is minimal. I may not participate in cleaning it, but I also try not to participate in making it dirty. I do not litter and I try to use the resources that I have (i.e. water and electricity) wisely, without abusing the privilege of having these resources at hand. I have seen places where clean water is a luxury and electricity is not available.
I live in a country of extreme wealth, and I am very much aware of the responsibility that comes with this blessing. As I educate and mother young people I try to instill in them the sense of appreciation for our world. It is my hope that all of them will become learned people who will have a great respect, compassion, and love for their fellow human being as well as for the creation surrounding us all.
