U.S. corn overproduction threatens farmers’ livelihoods, environment
By Abbas Nazil
The United States is facing a historic corn surplus in 2025, marking the largest harvest in its history—but instead of prosperity, farmers are confronting major financial losses and taxpayers are bearing billions in emergency federal costs.
According to Kathryn Anderson, Program Director for Food and Environment at the Union of Concerned Scientists, the root cause lies in chronic overproduction.
Farmers have been planting more corn than the market can absorb, leading to plummeting prices, environmental degradation, and economic instability across rural communities.
Anderson estimates that if U.S. farmers had planted about 11 million fewer acres, they could have broken even this season instead of losing approximately $160 per acre.
This oversupply, she noted, drove down farm revenues by about $159.50 per acre below the break-even point.
The environmental cost is equally alarming.
Excessive planting resulted in nearly 17,000 metric tons of nitrous oxide emissions—equivalent to what 1.1 million cars produce annually—and released about 170,000 metric tons of nitrate into water systems, contaminating rural drinking wells and harming aquatic life.
High input costs, weak export markets, and policies that encourage overproduction are worsening the crisis.
Federal subsidies and crop insurance programs create perverse incentives that push farmers to plant more even when markets are oversaturated, while taxpayers cover the resulting losses.
Anderson argues that the solution is straightforward: plant less corn.
She points to coordinated supply management, such as agricultural cooperatives and smart farm policies, as key to stabilizing prices and protecting both farmers and the environment.
By reducing acreage and focusing on fair market systems, Anderson insists that every farm family can thrive again—without sacrificing the land, water, and climate that sustain them all.
