The correct answer is - increased demand.
The increase in the consumption is a direct result of an economic progress in a country or a region, so when the people have more money to spend, they buy and consume more products. In essence, that means the increase in the consumption contributes to an increase of the demand for products, as the number of products that are used is getting constantly bigger. The bigger demand means that either the country itself needs to produce more (if its possible), or should import more from other places.
