Food security, or lack thereof, is a global issue, affecting millions of people worldwide. Although it has been determined that there is enough food on the planet to feed everyone, nearly one‐third suffer from some form of malnutrition. The purpose of this paper is to bring awareness to this global crisis. The introduction defines food security and food deserts, supported by global and U.S. statistics. Next, the paper discusses the federal and regional initiatives within the U.S. to eliminate food insecurity, including federal laws and individual state laws. The paper highlights the “Right to Farm” initiative promulgated by New York state, as well as the Farmers' Market of Troy, New York, as attempts to combat food insecurity. The paper then discusses another large metropolitan area in the U.S., Seattle, Washington, and its response to food insecurity: Seattle's “Farm‐To‐Table Initiative” and “Fresh Bucks” program. Next, the discussion turns to advancing technology and its ability to bridge gaps in food accessibility. For example, Sweden has implemented an unstaffed twenty‐four‐hour grocery store using technology to complete the transactions. Smiliar solutions are being tested in communities in China. Furthermore, Amazon GO, launched in 2016 in Seattle, Washington, is one of the most recent innovations, allowing shoppers to use an Amazon account to track their purchases. The paper concludes by calling on the more economically influential countries to prioritize food security in their respective nations. 相似文献

ABSTRACTCampus sexual assault (SA) policies and sexual consent definitions have not been widely studied. The study team conducted a nationally representative review of college and university websites (n = 995), assessing the prevalence of publicly accessible online policies and definitions and examining associations with school characteristics. A content analysis was performed on a subsample (n = 100) of consent definitions. Most schools (93.0%) had an SA policy and consent definition (87.6%) available online. Schools were more likely to have a policy or consent definition if they were large (≥5,000 students), public, or had a female enrollment of ≥33%. Detail and comprehensiveness of definitions varied. Findings highlight opportunities for schools—especially small schools, private schools, and those with more male students—to increase access to SA policies and consent definitions. 相似文献
