If everyone in the world speak the same language we could do much more and concurrently probably we will lost something which will be important to us. This thing has many advantages and disadvantages, that I enclose.
The most important advantages is chance no problems travelling in whole world and easy community with other people from other country. We then could no problem to understanding history and culture all country and feel good to be abroad. Nobody can not us trick and we can freely make dealings outside us country.
Secondly schoolchildren will have fewer examination, because they do not have learning different languages. It will be great, because it is very stresfull and often difficult. It would be easier, because people could learn and study in abroad, where are many better academy than in habitat. It would be chance for young people, who want advance in some direction, but nowadays it is impossible, because they afraid about different languages and communication.
On the other hand we will loss us national identity, because all country have different culture and history and often language in origin country or it is hard conncted in national identity.
Last but not least is fact that one languane in whole world would be boring, because all thing will happen generally available and too wasy, because now it let us lots of fun.
In conclusion I think that people should speak the same language in the world, because the life will be much easier.

If everyone in the world 'speak' SPOKE the same language we could do much
more and 'concurrently' (dla mnie to slowo tutaj nie pasuje) probably we 'will' WOULD (bo nie jestes pewna) 'lost' LOSE something which 'will' MIGHT be important to us.
'This thing' (Jaki thing? o czym mowa?) has many advantages and disadvantages,
'that I enclose' (po co to?).
The most important 'advantages is' (cos tu nie tak rzeczownik w l. mnogiej a czasownik w l. poj - powinny sie zgadzac) chance THAT THERE MIGHT NOT BE ANY 'no' problems travelling in THE whole world and easy 'community' COMMUNICATION with other people from other 'country' COUNTRIES.
We WOULD then HAVE NO PROBLEMS IN understanding history and culture
OF all countrIES and feel good to be abroad. Nobody WOULD BE ABLE TO trick US and we 'can' COULD freely make dealings outside 'us' (my? po jakiemu to - chyba naszego OUR) country.
Secondly schoolchildren 'will' WOULD have fewer examinationS, because
they 'do not have learning' WOULD NOT HAVE TO LEARN different languages. It 'will' WOULD be great, because it is very 'stresfull' (ortog) and often difficult. It would be easier, because people could learn and study 'in' (po co to 'in'?) abroad, where THERE are many better academy than in 'habitat' (zle slowo- znajdz inne). It would be A chance for young people, who want
TO advance in some direction, but nowadays it is impossible, because they
ARE afraid 'about' OF different languages and communication.
On the other hand we 'will loss' WOULD LOSE 'us' (znowu 'my' tutaj nasze OUR) national identity, because all countrIES have different cultureS and historIES and often language in THE originAL country 'or it is hard conncted in national identity' (tego nie rozumiem).
Last, (a co sie stalo z przecinkami- czy ich nie lubisz uzywac?) but not least, is THE fact that one 'languane' (ortog) in THE whole world would be boring, because 'all thing will happen generally available and too wasy, because now it let us lots of fun' (tego to nawet nie rozumiem).
In conclusion I think that people should speak the same language in the world, because the life will be much easier.
