What's wrong with this paragraph?

ScottsEnglish

There are a couple of disadvantages with international travelers. 

The first is that many of them come to a country with no plan to integrate into the community.

As a result, they can cause disharmony and even frustration for the local people.  Such a situation occurred in my local area and this led to loud arguments between an international traveler and a local shop keeper.

The second problem is that they often do not respect the local areas they are visiting.

On a number of occasions, I have personally witnessed tourists littering holiday areas.  These same tourists also left their accommodation in a terrible condition.  

These things are real negatives associated with international tourists.
