I don't share the same concern for Lyme Disease as the OP but I applaud the OP for acting out of his Christian belief.
Christians believe that God created earth as a gift for mankind. Along with this gift comes the responsibility of stewardship. That is our belief. The OP is acting out of that Christian belief and his conscience should be clear.
Riding in the mountains last month, filtering water from a mountain stream flowing out of a federally protected wilderness and taking in the vistas, I was in awe of what has been created for us and felt very grateful that those in the US and many other countries have been granted the wisdom to care for such a great gift.
I realize that religious conversations get pedantic quickly and that not all agree so this will be my only participation in this thread. I tend toward preaching by example instead of word because it offends less. Offense was not my intent.
