Farming areas for perennial plants can also provide protection for endangered species. Many are not aware that deserts are a net carbon sink, providing some relief from the increase in greenhouse gases. Research suggests that bacteria located in massive aquifers beneath the sand and in the sands itself, are capturing carbon from the air. Without the low humidity and desiccation, they are unlikely to have survived so well (17, p60). We are trying to benefit the planet, not just make money.
