Research help on the prons and cons of a car

hi!! guys i need help in my 1 week research about the prons (disadvantages ) and cons( advantages ) of a car , please help me guys ...

Hi!

Advantages:

Owing car,nowadays,means a lot.For instance,it gives freedom of driving for some people.(They can park wherever they want)
In addition,people may make their long-distance place as near as possible by driving car.

Disadvantage:

The fumes that come from cars cause serious problems in our lives including global warming.
Also,by driving car person may kill pedestrians unintentionally(or we may call it accident)

These are my opinions.
Good Luck!
