First disadvantage of owning a car is the expense. If I own a car I will have to pay not just the price of the car but additional costs like insurance, rufueling, and taxes. Second one is environmental problem. When I drive my personal car, my car will emit lots of contaminants. Rather than diriving a personal car, using public transportation will help saving the earth. The last one is reletive=related to health care. If someone owns a car and the weather is awful, he/she might drive the car even if it is a really short way. For instance, going to a supermarket. It can cause laziness. if it becomes severe, it will cause obesity, eventually,

Oh! Good thing we don't own a car yet. We are safe from the consequences you have mentioned above. :) Very good!!! Thanks Hye-Ji! See you.
