Just let me know what you would change about this world.  It can only be one thing though.  No wishes, so you cant wish for more wishes.  Also try and make it plausible.

For me I'd like to rid cancer.  

New episodes of SWAT Kats.

Easy answer.

No more suffering would be good, but unless a genie is granting wishing it's not possible.

I agree with you on cancer. But there are other terrible diseases too. Can we do away with all disease?

Exterminate the human race.

Just one. But you can name off more diseases if you want.  

Cancer is just caused by so many things now it is hitting people from young to old ages and it is so sad.  That is why I chose cancer.  Nobody is safe from it and it is becoming more common it seems.

In order to vote or be a public servant.. You have to prove you read and understand the original U.S. Constitution.

And still no one would buy it.

Sorry, I just had too.

I would rid the world of all of it's racism. 

Forget the ending of Bioshock Infinite to experience it all over again.

Well, that doesn't seem harsh at all!

The concept of nations must not exist. Humanity should be humanity and just that. But, because, of it, every nation is "no, this is mine", "No, I have to do this first", "No I can let them have that"; and because of that people in most parts of the world get treated like crap and forgotten, and because of that not so much progress as a race can be made.

I want to see how the identity of nations will be of any help when an alien race comes to kick our a$$ and make us their bitches.
