In addition, eliminating fossil fuels means................eliminating massive amount of cheap fertilizers made with natural gas!

There's another thing they never tell you about.

Fertilizer Made with Natural Gas Is Lifting Our World

Nitrogen fertilizers are made from of ammonia (NH3), which is manufactured using the Haber-Bosch process illustrated below:

This process, according to the SLAC National Accelerator Laboratory (part of the Department of Energy) has had incredible impacts:

Referred to by some as the most important technological advance of the 20th century….Between 3 and 5 percent of the world’s annual natural gas production – roughly 1 to 2 percent of the world’s annual energy supply – is converted using the process to produce more than 500 million tons of nitrogen fertilizer, which is believed to sustain about 40 percent of the world’s 7 billion people. Approximately half of the protein in today’s humans originated with nitrogen fixed through the Haber-Bosch process.

Haber process

Cause of population explosion

"Due to its dramatic impact on the human ability to grow food, the Haber process served as the "detonator of the population explosion", enabling the global population to increase from 1.6 billion in 1900 to 7.7 billion by November 2018.[23] About 1–2% of the world energy consumption and 5% of the natural gas consumption is currently used for the Haber process.

Nearly 50% of the nitrogen found in human tissues originated from the Haber–Bosch process"

metmike: Negative: Since nitrogen use efficiency is typically less than 50%,[20] farm runoff from heavy use of fixed industrial nitrogen disrupts biological habitats.[4][21]

Fertilizer History: The Haber-Bosch Process(using natural gas)     

Nitrogen is the single most important plant nutrient in today’s commercial fertilizers. It’s essential for making sure plants are healthy as they grow and nutritious to eat after they’re harvested. But today in agriculture, we take for granted N’s ready availability.

These advances in ammonia production have significantly increased yields of food and feed grain crops. In just 70 years, there’s been a six-fold increase in U.S. corn yields, thanks to the abundance of available nitrogen.

The world simply cannot do without N fertilizer, and the contributions made by Fritz Haber and Carl Bosch. Through fertilizer, we have the means to ensure that each growing season’s crops have the nutrients necessary to yield nutritious, bountiful foods for an increasing global population.

With Corn, you can see what this process did to yields on the graph below. The  introduction of nitrogen fertilizer caused corn yields to triple real fast and not as much to do with CO2 or weather during that initial tripling. However, recent decades have featured a steady increase, along with a steady increase in CO2 and beneficial growing weather.
