You hear way too often how agriculture practices are hurting the environment, but it's time to set the record straight. When it comes to doing more with less and taking care of the planet, agriculture has a VERY positive story to tell.
Farmers and ranchers are at the forefront of climate-smart farming, putting scientific solutions, technology and innovation to work to protect our land, air and water. For instance, did you know that U.S. agriculture contributes around 10% to overall greenhouse gas emissions by economic sector, but thanks to farmers’ dedication to conserve natural resources, that share drops to negative 2% when additional carbon absorbing practices are factored in.
Not only are agriculture’s overall emissions low, farmers and ranchers are taking active steps to make their footprint even smaller:
• For example, farmers are converting waste into energy, and they are participating in conservation programs, which preserve green spaces (like grasslands, forests and wetlands) that absorb greenhouse gases.
• More than 140 million acres of U.S. farmland are used for conservation efforts and wildlife habitats—that land area is equal to the states of California and New York combined.
Let's break down ag's environmental impact. Regarding efficiency and productivity:
• Over the last 70 years, U.S. farms have nearly tripled in production while the amount of resources used (including land, energy and fertilizer) has remained rather stable.
• Compared to 1990, farmers would have needed almost 100 million additional acres to harvest the same amount of corn, cotton, rice, soybeans and wheat they produced in 2018.
• Livestock emissions continue to make up less than 4% of overall GHGs by economic sector. Meanwhile, U.S. farmers have increased production while decreasing per-unit emissions.
• In the past nearly 30 years:
- Dairy and milk production has increased 48% while per-unit emissions for dairy have declined by almost 26%.
- Beef production has increased 18%, while per-unit emissions have fallen more than 8%.
- Pork production has increased 80%, while per-unit emissions have fallen nearly 20%.
Regarding renewable energy:
• Farmers aren’t just adopting eco-friendly solutions; they are also growing solutions through clean and renewable energy.
• Homegrown biofuels are playing a significant role in reducing GHGs. According to a study by Harvard and Tufts University and Environmental Health and Engineering, Inc., increased utilization of biofuels under the RFS has led to a 980 million metric ton reduction in greenhouse gas emissions between 2008 and 2020. That’s equivalent to taking 18 million cars off the road annually!
So you see, agriculture and the people who grow your food are consistently looking for ways to improve, and do more with less. Thank a farmer!
