What was the long time impact of Europeans settling in the Americas

The long impact would be the bringing of European culture and tradition to the new continent, that included religion, language, technology, even diseases and certain cultures.

Explanation:

Europeans didn't adapted to the New World as much as they adapted it to their needs. They brought their governing system, Christianity, their languages, culture, but even diseases that killed many Natives. Of course, because of this we can say that even the ecosystem in the New World has changed.
