How did mercantilism and the establishment of colonies lead to increased global trading during the 17th and 18th centuries?

it lead to increased global trading because when the colonies established there was another place to trade with, not only for england but also for other places like Africa and the british west inides. And it was over the world hints the Word "global". And mercantilism because it said the colonies HAD to send for example wood to england then england would make a chair and send it back anf th colonies would buy it. That's trading instead of the colonies just making the chair, then there wouldn't be as much trading.
