do you mean some good (=powerful, etc) examples for negative aspects of globalization? I'd say:
-The loss of indigenous cultures and languages, such as West Greenlandic dialect
-Spreading inequality, such as when one country is a cheap labour and "brain drain" in benefit of another
-Negative effect on health by the spread of fast food chains and the popularization of non-local food (which needs to be chemically preserved to be edible, while the local food can be eaten fresh).
