Some people think that we haven't GOT any influence on 'them' (do czego/kogo 'them' sie odnosi nie jest wyrazne) , but I believe that an individual person can solve almost any problem.
Firstly, if a person is in a high position he can 'controls' (nie, bo tutaj HE can control) a lot of 'thing' (tutaj l. mnoga) without any agreement (ale z kim ma ten 'agreement' byc?). For example, our President (duza litera) 'haven't' (juz mnie to wscieka, prosze nie uzywac kolokw ktore gdzies tam w kiepskim filmie uslyszales, tu ma byc DOES NOT HAVE) to ask anybody to introduce new regulations. (To nie jest calkowicie prawda, bo zgoda musi byc)
He 'know' (prosze dostosowac czasownik do 'he') what to do and 'have' (*he have? od kiedy?-popraw) made our country A (znowu z tymi przedimkami - co z wami jest - prosze ich uzywac!!) better and A safer place.
For example, if we want to influence A change in society and if we know what to do,somebody who 'have' HAS A similar problem 'like' TO us, 'surely will include to us' (tego nawet nie rozumiem).
On the other hand, too many decisions are made by people in high
position and when 'we are pure' (pure- czysty jak lza?) or we're not AN important person, nobody 'listen' (nie, prosze dostosowac czasownik) to us. ...That is often works and made people to think....(tego nie rozumiem)
On the other hand sometimes people lose their 'creative' (zle slowo-popraw) and ambitions, so 'don't doing nothing' (co to za bzdury - prosze poszukac to w podreczniku/ksiazce i napisac poprawnie) to change our society. However, having considered all the pluses and minuses, I believe very strongly that it's possible for an individual to influence A change in society.
