For and against essay about one language on the world

Uprzejmie proszę o sprawdzenie rozprawki maturalnej.

The idea of making uniform language on the whole world have accompanied the mankind from ages.In XIX century scientists have been worked on new artificial language - Esperanto. Nonetheless, already in the Middle Ages , Latin was dominating and was believed to be better than other. Later function of international lanuage have been repossessed by French and, in XX century, by English.
There is no doubt that the bigest advantage of existing one sole language on the world would be enormous convenience. People wouldn't have to spend many years on learning second language to understand each other. It may be helpful for example in journey.
In addition, everyone could have the same chance to education. In current world most publications in the Internet are in English and the best universities require pass english test on high level.
In the other hand, language is very important ingredient of our national idenity. If it was one language, wide variety of culture would vanish. Inclusivity is very significant from point of view arts. Nation's traditions are inspiration to create literature, music etc.
Moreover, learning other language enhance possibility of our brain and broadens horizons. In each language is contained so-called 'linguistic world view'. In a nutshell, linguistic world view theory says that in each language is concluded the interpretation of reality, characteristical for one culture, fixed in grammar, vocabulary etc. Thus, while learning other language, simultaneusly we get to know other way of viewing.
To sum up - maybe one universal language on the whole world would be more convinient but I personally and strongly believed that language diversity is ridicolous and with reason God scrambled up languages on the Tower of Babel.

The idea of 'making' (daj wyzsze slowo, np. 'creating') (brak przedimka) uniform language 'on' (zle slowo, tutaj 'for') the whole world 'have' (ale to ma sie zgadzac z language') 'accompanied' (dla mnie nie za bardzo trafne slowo) 'the' (niepotr) mankind 'from ages' (to wyglada bardzo kolokw. moze 'from centuries').In (brak przedimka) XIX century scientists 'have been' (niepotr) worked on (brak przedimka) new artificial language - Esperanto. Nonetheless, already in the Middle Ages , Latin 'was dominating' (nie, napisz 'dominated') and IT was believed 'to be better than (brakuje 'any')other' (nie tyle ze 'better' tylko, ze to byl wtedy 'universal' lang). Later function of (brak przedimka) international lanuage 'have been' (zly czas, tutaj simple 'was') repossessed by (brak przedimka) French and, in XX century, by (brak przedimka) English.
There is no doubt that the 'bigest' (ortog ale i tak, postaraj sie o wyzsze wiecej 'oficjalne' slowo) advantage of 'existing one sole language' (nie, pokreciles troche, tutaj ...one sole lang. existing') 'on' (nie, tu masz kalke z polskiego 'na, ale po ang 'IN) the world would be (brak przedimka) enormous convenience. People 'wouldn't' (napisz to w calosci) have to spend many years on learning (przedimek) second language to understand each other. 'It' (nie za bardzo jasne, do czego to 'it' sie odnosi) may be helpful for example in (przedimek) journey.
In addition, everyone could have the same chance 'to' (zle slowo) education. In (przedimek) 'current' (poszukaj inne slowo) world most publications 'in' (zle slowo) the Internet are in English and the best universities require (przedimek) pass IN AN 'english' (duza litera) test 'on' (zle slowo) (przedimek) high level.
In the other hand, language is (przedimek) very important ingredient of 'our' (dlaczego tylko 'naszego' - nie przypuszcza, ze to nie odnosi sie tez do ludzi w 'Darkest Africa') national idenity. If it was one language, (przedimek) wide variety of cultureS would vanish. Inclusivity is very significant from (przedimek) point of view (brak 2 slowa) arts. (przedimek) nation's traditions are (przedimek) inspiration 'to' (zle slowo) creatING literature, music 'etc' (nie pisz etc' bo jeszcze nie widzialam/slyszalam o artyscie ktory tworzyl 'etc').
Moreover, learning ANother language enhanceS (przedimek) possibility of 'our' (nie pisz tak, lepiej 'the') brain and broadens (cos tu brak) horizons. 'In each language is contained' (napisz to biernie,...Each lang. contains the) so-called 'linguistic world view'. In a nutshell, (przedimek) linguistic world view theory 'says' (nie, daj 'states') that in each language 'is concluded the interpretation of reality' (napisz to biernie...an interp....), characteristical for one culture (daj tutaj pare slow...which is) fixed in grammar, vocabulary 'etc' (tego nie rozumiem, jak 'language moze byc 'fized in 'etc'?). Thus, while learning ANother language, simultaneusly we get to know ANother 'way of viewing' (nie, to nie tak, daj tutaj 'viewpoint').
To sum up - maybe one universal language 'on' (zle slowo) the whole world would be more 'convinient' (ortog) (przecinek) but I personally and strongly 'believed' (zly czas, daj tutaj teraz.) that language diversity is 'ridicolous' (ortog) and with (tutaj mozesz dodac 'good') reason God scrambled up languages on the Tower of Babel.

Zrob cos z tymi przedimkami (a, an, the). Dlaczego ich nie uzywasz?

Dziękuję serdecznie, gramatyka to moja bardzo slaba strona, ale z tymi przedimkami to faktycznie przesadziłam.

nie znalem imienia Petronela :)
