The Environmental Protection Agency's program, Design for the Environment works with individual industry sectors to compare and improve the performance and human health and environmental risks and costs of existing and alternative products, processes, and practices. DfE partnership projects promote integrating cleaner, cheaper, and smarter solutions into everyday business practices. [13] The Design for the Environment program is also equipped with a labeling program. They allow safer products to carry these labels and they are an indication to consumers that buying these products will be safer for the environment and their families. [14]

In addition, other elements conspire to take away from the harvest for which we worked so hard to produce. Despite the best application of modern agricultural practices, an unavoidable portion of what is grown rots in the fields prior to harvest time, or in the world’s storage bins afterwards. Every year, depending upon geographic location and intensity of El Niño events, crops suffer from too little water and wither on the spot, or are lost to severe flooding, hailstorms, tornados, earthquakes, hurricanes, cyclones, fires, and other destructive events of nature. Many of these phenomena are at best difficult to predict, and at worst are impossible to react to in time to prevent the losses associated with them. In sub-Saharan Africa, locusts remain an ever-present threat (42), and can devastate vast areas of farmland in a matter of days. Even after a bumper crop is realized, problems associated with processing and storage lessen the actual tonnage that is available to the consumer. A large portion of the harvest, regardless of the kind of plant or grain, is despoiled or a portion consumed by a variety of opportunistic life forms (., fungi, bacteria, insects, rodents) after being stored. While it is conceded that at present the abundance of cash crops is more than sufficient to meet the nutritional needs of the world’s human population, delivering them to world markets is driven largely by economics, not biological need. Thus, the poorest people – some billion – are forced to live in a constant state of starvation (43), with many thousands of deaths per year attributable to this wholly preventable predicament (44). Locating vertical farms near these human “hot spots” would greatly alleviate this problem.
