Viewpoints: Why overlook agriculture in considering climate change?

Eating meat is bad for the planet, right? That hamburger you're contemplating for lunch comes from a cow that, most likely, was raised within the industrial agriculture system. Which means it was fed huge amounts of corn that was grown with the help of petroleum, the carbon-based substance that has helped drive Earth's climate to the breaking point. In industrial agriculture, petroleum is not only burned to power tractors and other machinery used to plant, harvest, and process corn – it's also a key ingredient in the fertilizer employed to maximize yields.
