Step-by-step explanation:
Collecting crops from fields that have either been harvested or are not profitable to harvest is known as food salvage. This practice is a way of reducing waste and making use of produce that otherwise would not be sold in the market.
Food salvage can include gleaning fields after the main harvest is done and collecting crops that have grown outside of the production area, or those that are not economically worth harvesting for the farmer.
Food salvage is part of a broader movement to prevent food waste and can help support food security by redirecting food that would be discarded to those in need. It is also related to other practices such as perishable food rescue and prepared food rescue, which focus on recovering food from retail, dining, or catering outlets before it goes to waste.
Additionally, policies like government subsidies can influence what happens with crops, whether they are grown for food, or biofuels, or left unharvested due to overproduction. The correct answer is a. food salvage.
