I know ya said ya hear me, but its important to understand: although there may bee quite a few different introduced 'cultivar' running loose in your area, one never knows where the weak link is. When dealing with the environment, one is dealing with a complex interconnected system. Simple causality doesnt apply here. Introduce the wrong species- and IF it effects the right (read: wrong) specie(s) within that system the wrong way, it can create a huge ripple effect that probably wont bee immediatly apparent, but can cause serious problems further down the road.
Like I said, I appologise for preaching, I know how irritating it can bee to have some asshole (especially one you dont know) try and tell you what they think is wrong or right. The only reason I am doing this is because I believe alot of people number one arent even aware that doing this sort of thing can cause a problem and number two, if they are aware- it usually isnt their top priority to pay attention to it, especially when they see every other asshole doing as they please without a second thought.
like I said, I hope Im not coming off like Im lecturing or holyier than thou- I certainly am not.
My mom tells me Im good lookin'!!!
