Synthetic fertilizers are one of the biggest reason the human population is so large today. We can take atmospheric nitrogen (N2) and with some water we can make hydrogen gas. Combine atmospheric nitrogen and hydrogen gas under high heat and pressure, and bam! Liquid ammonia (NH3). And ammonia is the basis for most fertilizer. Without this ability to synthetically create ammonia, scientists estimate our population would be much smaller, less than 4 billion people today (under ideal circumstances, even with today’s organic farming methods).
And while this achievement is great, it has led to environmental catastrophe. Runoff nitrogen creates algal blooms, turning healthy ocean and rivers into anoxic, deadly environments for waterfaring creatures. Every improvement can have its pitfalls.
What do you do to protect the environment? Do you recapture runoff from your plants? Do you farm only organically? Tell me more.
