If you live in urban areas what are the problem of urbanization?​

the world's urban areas are highly varied, but many cities and towns are facing problems such as a lack of jobs, homelessness and expanding squatter settlements, inadequate services and infrastructure, poor health and educational services and high levels of pollution

Well, where I live it is very polluted. You do not want to live here if you have asthma. Another con is that with all the people and homelessness, it's a well known fact here that if you leave your car unlocked it's gonna get searched by some stranger. You do not want to keep your wallet in there. It's not like I life in the ghetto though, the place where I live has plenty of pros to.
