Graffiti is an urban art

Today I am going to talk about the urban art of graffiti.

there are arguments for and against,and everyone has a strong opinion.

On the one hand people like graffiti in their town because 

graffities are beautiful and very difficult.

There are a lot of competitons and people raise money for the local economy.

On the other hand people don't like graffiti because the walls get dirty and if they want to delete they have to pay a lot of money.

In my opinion I like graffiti because it's really beautiful and I enjoy walking around streets where I can see lots of graffiti.
