Answer:
The author uses pathos to develop his argument by chastising the reader for the destruction of the environment.
Step-by-step explanation:
"To disregard the diversity of life is to risk catapulting ourselves into an alien environment". The author here is clearly stating that not caring about nature is gonna put us in a situation there we are not supposed to exist. Maybe an era without nature, or with a very harsh one. Things will change and not for the better. "We will have to become like the pilot whales that inexplicably beach themselves on New England shores", meaning that to find solutions and to navigate the new era that we will enter for neglecting Mother Nature, we will end up blind to what the future will be like and most likely, we will not even know where humanity will be going to end.
Also, it is important to notice that by using the imagery of the whales and by using the term "mother nature", its quite clear that the author is trying to provoke an emotional response.
