Religious road shows

Not one but all religions do parades, which results in blocking roads, and hard to manage public, and this happens atleast once a month, why religious parades have to block traffic, disrupt people’s work. Rather these events should occur in an open field, organisers must take responsibility for traffic and parking, they must clean after the event. Also throwing religious customary stuff in water bodies should be banned. There should be alternative like small diy thingy at mandirs where people could do this kinda ceremonies rather polluting rivers
