About why europeans traded spices( i think)

2 examples.

First is yes it is good to trade because if Europeans trade they can earn alot of money and can trade with other country and know more about it so that is my opinion about why europeans traded spices.

Second reson is i dont really have a reason about the bad about trading so i dont have opinion about the bad one.
