"The more Fair Trade USA products sold, the more producers receive the benefits of the fair trade system, and the stronger the system."

Explanation:

"Fair Trade," from the name itself, is all about trading fairly. This is done by supporting the farmers who are considered to be the most marginalized sector in the society. This protects workers and farmers, especially against the fluctuating prices in the market. It also gives them a communal fund which they can use for healthcare, education or any expenses that they see fit.

"Fair Trade" also encourages the consumers to buy the produce of the farmers. This can help ensure economic growth that is related to "food security."

In relation to the situation and answer above, the more Fair Trade USA products are sold, the more people buy products from the farmers. Many producers are then able to receive the benefits, thus making the Fair Trade System stronger.
