Contraaaaaaa

Many contraversial issues are brought into Brave New World. The fact that the world's original history can not be taught how it is now adays is an extreme strong thing that seems to really (I guess you could say) antagonize. Our world would be no where if we didn't know about our history and universe's past, however the people in 'Brave New World' have a different view."'These,' he said gravely, 'are unpleasant facts; I know it. But then most historical facts are." (Ch. 2)
Also just the fact of drug use is a big issue, because compared to now drugs are looked at and frowned upon but in the book it seems to be a dependent neccessity (soma) for everyone to live a happy life. If you look at the world now, people who smoke to make them happy is completely illegal.
Cloning, although in the book it isn't directly looked at as that, is an issue too. Cloning now is still being researched and has both it's positive views but in BNW, it seems like there is no indivituality and everyone is created and designed to function just the same
