Did you know that there is an estimated 1 billion cattle in the world? That is almost one for every 7 humans.

India and Brazil account for 53% of the global population of cattle while China, the United States, the European Union, and Argentina account for 33%.

A single dairy cow can produce around 150 pounds of feces each day. For much of human history, this manure would have been used to fertilize agricultural fields, providing them valuable organic matter and nutrients. But in modern dairy production, cow poop is typically considered a waste product, destined to languish in manure lagoons that release vast amounts of methane, a potent greenhouse gas.
