Difference between world trade and fair trade?

Fair trade is something for our 3rd world. When you buy something like fair trade chocolate the poor people who make the cocoa beans are guaranteed the same good money every time. So the poor people never go too hungry if the price of cocoa beans dropped because they will be payed the same.

Generally world trade is just the world trading. Like we cannot grow grapes so France would grow them and we will trade with France and other countrys for other objects for something that we grow or our money.
