I think graffiti is an art, but someone has been graffiti on walls, buildings and other public places, so most people think it as vandalism.
Graffiti started thousands of years, people carved messages into tree trunks and rocks,walls,trains and road signs are the most common places to see graffiti today.
The most basic form of graffiti is the graffiti artist ‘s personal signature, they writes the signature in large stylized letters. Graffiti artists try to paint their tags in as many places as possible. Fewer graffiti tags appear in cities with lots of murals, many cities allow artists to paint murals in the hope of reducing negative types of graffiti.
Graffiti can create a bad impression. Cities spend thousands of money a year to get rid of graffiti, but some countries have programs to educate youth about the problem of graffiti, how about your opinion on graffiti?
