• Forty percent of the Earth’s land area is arid or semi-arid, much of it degraded and very challenging to farm. Increasing amounts are turning to desert.
• This land supports one-third of the human population of our planet and the majority experience extreme poverty.

• Could the vast agricultural waste from the [hundreds of millions of] agave plants processed annually by the Mexican tequila [and mescal] industry point to a viable solution for people, livestock and the planet?
