Criticism

Globalization is a good thing, but it also has many down sides. It's not good for the local economies, it makes the uniqueness of the different cultures go down, and it also can cause the spread of diseases.

 Economics: Globalization can be good for the large companies, but it is really bad for the local economies. This is because all the people are staying in the known hotels like the Marriott or Holidays Inn and not staying in the hotels ran by the local people. This causes most of the money the visitors are bringing in to go to the big companies instead of staying in the local towns and that destroys their economies.

 Culture: Cultures are changed or even wiped out when other cultures come into contact with it. Most easily seen by people are examples of the African tribes taken over by white people. While white people argue that that they bring new social and cultural developments, but the tribes being taken over already have their own forms of religion, politics, and justice systems. When they clash together, they either have to compromise, or the stronger culture takes out the weaker by force. This destroys heritage preserved for many generations and replaces it with a system that the people aren't used to, which further explains why globalization isn't a good thing.

 Diseases:  When people travel to different countries they get vaccinated for the more common diseases, but they don't get vaccinated for the less common diseases that are also known to those countries. When people travel and get those diseases and bring them back to their countries it will spread to those people. This will cause there to be more diseases in the country the people are traveling home to and diseases they know nothing about. That is just another reason why globalization can be a bad thing.
