Answer:
I think it is B: A spiritual connection to the natural world.
Step-by-step explanation:
This is because A is not really the tone the lines are conveying. Also, the lines dont seem to show that the author is prideful of his good works, because it seems kind of sad rather than happy. And though it may convey sadness, it does not talk about the decline of a healthy planet. So, I think the best option is B.
