Nowadays, people want be to in good shape and eat 'healthy' (healthily). Lots of 'youngster' (tutaj l. mnoga) and elderly 'pick up' (nie, poszukaj inne slowa) some sports. 'For example cycling' (czy te 3 slowa to jest poprawne zdanie?). This activity 'recquire' (ortog i pamietaj activity-3os.l.poj) special paths. 'Unfortunatly' (ortog), building these 'lines' (tutaj trzeba jasno wyjasnic ze chodzi o specjalne bike paths) 'take' (it-3os.l.poj) space on the roads.
'For first, safety' (nie, to nie jest poprawne zdanie. Lepiej, Firstly, safety needs to be considered, albo Firstly, we need to consider safety.) It is the 'main' (poszukaj lepsze slowo) matter in this case, especially for 'bikers' (nie, chyba masz na mysli 'cyclists'). People, who 'riding' (nie, tutaj 'cycle') on two wheels are in (przedimek) bigger danger than people who ARE travelling by car. Bikes are not equipped with belts, and all these 'safty' (ortog) 'system' (tutaj l. mnoga, bo masz slowo 'all' a to znaczy wiecej jak jeden) like ABS. 'Disconnect' (nie rozumiem tego slowa tutaj) two types of transport seems to be (przedimek) great solution for them.
In big cities people waste 'uncounted' (poszukaj inne slowo) hours waiting for (przedimek) green light. Building even little paths 'make' (tutaj 3os.l.poj) asphalt roads much 'more' (niepotr) smaller. It is harder to 'cummute' (ortog) to work when you can use only two lines on your side instead of three.
Summing up all pros and cons. I strongly believe that local government should build new paths like in Western Europe. There 'cyclist' (daj l. mnoga) ride in the middle of the whole road. It 'dont' (does not) take a 'lof' (ortog) of space and car drivers are more 'carefully' (zla czesc mowy, tutaj 'careful'). It is (przedimek) great idea to improve our 'safty' (nie rozumiem dlaczego raz piszesz to slowo poprawnie a innym razem z bledem) in (przedimek) very simple way.
