I think your question needs to be a little more specific. International Organizations can be broken down into NGO's (non-profits and international corporations), IGO's (sovereign states, UN, WTO). A positive and/or a negative role will depend on who's asking. I grew up in Brazil and back then the IMF was a villain, ask an American and the answer wil be the opposite. The same goes for the UN, the WTO or Coca-Cola. They do play a positive role but they also have negative roles. What specifically are you looking for?
Tourism has an enormous negative impact on the environment, both natural and man-made.
If a baby will have a negative environment, it will effect him in a negative manner. He/She will have negative thoughts. And it is our thinking that makes us good or bad, rich or poor etc. So it is very important for a baby to have a positive environment. ;)
