In my city (and also in a lot of other places in my country) there is a lot of litter in the street. Very often the government cleans the streets. But after every day the streets are full of litter. In some neighbourhoods there is a lot more litter than in others (the poor neighbourhoods with a lot of foreigners). But everywhere there are antisocial persons who are putting there cans, bottles etc. in the streets and not in the litter bins. That behavior is irritating me. Why are so much people so irresponsible? And why is it getting worse?
