Tree hugger and frotter and kisser from waaaay back....work to retain more big old trees in our towns and cities, accept where we are not willing to give them space and work from a position of informed knowledge rather than blind absolutism on either side.
You know even accepting the derogatory definintions without some of those "chained to tree individuals" you wouldn't have many of the (limited) national parks that increasing play a critical role in the rapidly altering environment in which we all live, its worth considering that over our brief occupation of this earth the things we accept as being right and proper have changed somewhat (with respects to our role in extracting resource from the earth) and often (not always!) those who have argued for conservation and having strict limits on our insatiable desire to consume have presented a more sustainable model.
Hindsight is great, but you really want to hope that we don't need to rely on it in the next 100yrs!!
