I don't think it's crazy at all to protect trees. We need them. What baffles me is how much we rely on them and still cut whole swaths of them down anyway without a thought.
Study after study has shown that trees in cities offer huge benefits: offering shade and cooling (reducing energy consumption), draining storm/flood water (very useful in our more extreme climate), cleaning the air and emitting oxygen, homing wildlife, improving mental health by reducing anxiety and depression, being nice to look at.
Every city tree should be treasured and protected.
I get a lot of flack for my belief in other animals deserving agency. You're the first person that's ever agreed with me on that. Usually people get aggressive and call me names, and tell me I'm crazy, or a wack job, or any other number of names.
