"should tourists be banned from our country"

It is a problem.Tourist will bring money and spend in the local.At the same time,there is litter and graffiti leaves in the path by tourists.and tourists will make hotel full and food price raise.it will bring convenience to local population.The saddest aspect of mass tourism has been brought to the attention of the public.i do not how to do then.

No the only bad habits that America prohibits their tourists from is terrorism, smuggling and staying here after your Visa has expired. Short of these three you can pretty much do what you want. Our inhabitants already pretty much are used to bad habits of all descriptions.

I don't think that banning tourism will eliminate the problems of "bad habits". Let's face it, with the Internet and Television, most people are aware of what's going on in the world and will not be subject to the negative influence of tourists. In fact, if a country can promote tourism in safe areas, it will bring more and more economic stability to the country. Tourism has more advantages for local economies than disadvantages, I would think.

what is your country please mention i think they must for any country

Well, what country are you talking about? I don't think they should. Look at North Korea. It ruins some of the income the government gets and it's unfair to people. If someone wants to go visit another country I don't see why they shouldn't. What undesirable habits could they introduce?
