Garbage Everywhere after Canada Day

Every time there is a public celebration you can find garbage all over the place. I think it is time that people learn that common decency applies even during these festivities and that they should not throw garbage about.  Walking to work, I could see owners of businesses sweeping away strewn paper, paper cups, bottles etc.  It takes a lot of work.  If we all did our part we could all enjoy ourselves and respect the environment. 
    Perhaps there needs to be more garbage containers around and perhaps if a few students could be hired to make frequent announcements reminding people not to litter, it might not be so bad.  We can all be shamed into putting our garbage in the proper place. We are living in a civilized society but each time there is a public  community festivity we seem to revert to our animal instincts. Okay, I get it. Then these town-criers would help us to remember that we are in fact human beings.
