Who is in charge of the planet? What do Nikki, Jackie and Ben think about it? Prove it from their stories

First of all i want to tell you that my name is nina and i am 15. a few   words about my appearance. my height is nearly 149 cm. but i'd like to be a bit taller. well, i am not slim but  i am  not fat either.  i have a round face as everyone has, a bit long nose and big cheerful grey eyes. my skin is a bit pale but i like this fact, i don't like ruddy faces. i have no  freckles as my friend olga has. my forehead is open. i think i have a charming smile.  my hair isn't very short but it's not long either. it is  straight and  black. i think that i look like my her father. i am very active and creative, cheerful and curious. but the best thing is that i'm reliable.
