This spill caused so much damage to the ecosystem and the environment of the Gulf of México.
The two details from the text that support the answer are the following. The author, Kate Jackson, writes that the BP company knew about the possibility of an accident of this magnitude but it didn't do anything to prevent it. She said that David Rainey, an executive form British Petroleum, had assured the members of the Senate that the facility had no risk of a spill.

"The domesticated generations fell from him" means that Buck is losing his civilized characteristics (B).
In this passage, Buck is feeling more and more estranged from where he and his ancestors ("generations") originally come from: as he gets a taste of wild life, he feels less and less like a pet ("domesticated") and more like a feral dog or a wolf. He is forgetting his stay-at-home ways ("fell from him") and sees new instincts grow in him, such as the drive to fight and hunt in a pack.
