BP Oil Spill: Effect on us, and our perhaps our future?

[Curiosity Never Hurt]

I came across an article of a doomsday theory regarding the BP oil spill:

Of course, this article may not be entirely true as it is very far fetched in nature, but it made me wonder how the BP's operations have affected the general population around the world.

 

For instance, what did the event cost us financially and environmentally?

How do these events relate to the everyday person?

How did this affect our future?
