What made trade in New England easier?

The triangular trade made the trade easier sometimes they would trade slaves food like sugar Cain, tobacco,corn,rice and sometimes wood to make new boats that's why we had so little trees in new England because they would cut them down and soon grow right back but it was hard to do that because it would take long to even cut the trees down, it would take long to put them on the ship too!,also growing them back(thats just plain slow!! And are stupid for cutting down all those trees!.
