If theres a huge surplus of a product, theres not much demand for it since the product is readily available. You see this with subsidies. In the great depression the government paid farmers to lower supply of corn, which created demand and increased prices.

When there is a huge surplus of a commodity, the unmet demand for it disappears but the number of units consumed increases because the price decreases. For example, lower corn prices lowers the cost of beef, which results in more consumption of corn, and an increase in the production of beef and a corresponding increase in the consumption of corn.

Governments sometimes pay farmers to reduce acreage planted in a particular crop and sometimes they purchase and stockpile the commodity for the same reason - to raise its price. These efforts to provide price supports for crops and if successful, they will reduce the consumption of the product.
