I don't like discussing some ideas with my parents. They usually think i'm crazy.
Today there was some bad news about food safety.A compay which  supplies meat to KFC，Mcdonald's and Pizza hut,uses bad meat.Thier meat are exceed the time limit by some months.A lot of beef has turned green,but it is still consumed by humans.That's so terrible! I can't believe it is true.Why can they do such scurviness things?Why don't they care about others who eat these meat?Could it be said that they have no idea that one day their children might eat this rotten meat?
I'm angry and helpless.But when I talk about this news with my parents.They are indifferent.They just enjoy watching Korean TV plays.Although I love my country and I love pure air and healthy food more.I want leave to here,but my parents think I am crazy.I 'm puzzled.

I don't like discussing some ideas with my parents. They usually think I am crazy.
Today there was some big, bad news about food safety.A company which supplies meat to KFC，Mcdonald's, and Pizza hut, uses bad meat.This meat is quite a few months out-of-date.  A lot of beef has turned to green,but is still intended for human consumption.  That's so terrible! I can't believe it is true.Why can they do such scurrilous things? Why don't they care about others who eat this meat?Could it be said that they have no idea that one day their children might eat this rotten meat? 

I'm angry and helpless.But when I talk about this news with my parents, they are indifferent.They just enjoy watching Korean TV plays.Although I love my country,I love pure air and healthy food more.I want to leave here,but my parents think I am crazy.I 'm puzzled.

[Not sure what you wanted to say with "scurviness".  I guessed and inserted "scurrilous" which means "underhand"] Good try.
