Street hawking is probably the most risky kind of trading in the whole world.The streets are mainly for vehicles.The sidewalks or pavements are not big enough for pedestrians,let alone,hawkers.
The inability of the authorities to enforce the law and maintain discipline is the main cause of street hawking.The law is probably not enforced consistently .
In addition,lack of formal and informal education is another cause of street hawking.If the public is educated from their youth about the dangers involved,even if the hawkers invade the streets,there would be no customers to buy their items
Poverty is one major cause of street hawking.Most people do not have the means to secure or rent authorized places to hawk their items.
