Human sustainability is a term that is often misunderstood. And yet, it is a term that is frequently encountered in economic, environmental and public health policy-making. What does the term mean and can human sustainability ever really be achieved? In "From Asparagus to Kilowatts", Dr. M. Jerome McFarland explores how the application of simple resource recovery is a vital step towards achieving human sustainability. The reader is taken on a rudimentary journey that creatively illustrates how economically valuable products such as clean water, crop fertilizers and renewable energy can be inexpensively and efficiently recovered from domestic wastewater processing. "From Asparagus to Kilowatts" clarifies how, through local recycling of these recoverable products, natural material balances are successfully restored. The returning of environmentally important materials to their place of origin effectively minimizes the environmental footprint of human activity - a basic requirement in defining human sustainability.
