What Farmers Say About Climate Change
This is probably the most honest assessment of the current state of farming and our future food supply.
True: plants love CO2.
Also true: plants love warmth and water.
Also, also true: it’s not the CO2 (aka “plant food”) itself that’s the problem. It’s the resulting changes caused by rapidly rising atmospheric CO2 levels. Too much climate unpredictability, weather variability, heat, drought or water will destroy agriculture. That means shortages and famine.
Civilization is built off the back of agriculture. And agriculture requires a foundation of predictability and good soil. Without predictability, agriculture isn’t sustained and we once again become a species of hunters, foragers and nomads. While that worked 10,000+ years ago, the human population today is far too large and we would soon starve.
Climate change may push wild plants into areas in which they don’t currently flourish, but this has nothing to do with our ability to sustain an 8 billion population with industrialized agriculture. There is a reason why farming is concentrated in certain regions of the world: good climate and good soil.
The new areas in which plants may flourish aren’t necessarily ideal for growing fields of wheat, soy or corn. Even if they were ideal, it would take a significant amount of time to a) confidently identify these areas and b) build the necessary infrastructure.
If given a century or two, perhaps we could adapt to a changing environment. Unfortunately, the current pace of change risks multi-breadbasket failure in the near future.
