Is colonization good?
Short term- extremely bad, can wipe out entire populations (Native Americans) but at the same time, can be good by bringing new technology. This could be bad through, because the populous could not know how to handle the new technology.
Long term- can be good or bad.
The nations that arise from Colonization, such as America, can be extremely influential and become a great nation.
It’s important that the country that starts the colonization encourage a new country, and that it lets it be independent if it wants to.
