What were the different outcomes of European interactions with Africa, India and the Americas?European's had interaction with many countries such...

To me, the impact of Europeans on these areas were quite
different.  The Americas came out the worst, especially in North America.  Africa was
hurt badly by colonialism, but not as badly as the Americas.  India was relatively
unharmed (but only relatively).

India came out pretty well
because it was colonized by only a few Europeans with much of the work (even of
governing) being done by Indians.  So the Indians kept their country and much self
rule.

Africa was hurt badly by having so many people taken
as slaves (West Africa) or by having people subjugated (South
Africa).

North America's natives were essentially all
killed, which is why I say the impact on them was the worst.
