Attiring global food security and restoring demands on the environment is the greatest challenge faced by mankind. By the time 2050 at least nine Billion people need food, and increasing incomes and urbanization will inevitably lead to dietary revamp. The food security competitiveness will increasingly fringe the triple burden of malnutrition– undernutrition, obesity and deficiencies in micronutrient. The importance of the food security issues has led to huge scientific strides which forwards and making it difficult to keep up with the rapidly expanding value of scientific research and technology. Policies to implement global and local food security needs to be actualize and decision makers should have to make difficult choices to ameliorate the food security of local people against the limelight of drastic global changes. For some, feeding the world ethically means ensuring universal access to what is needed nutritionally for human survival and mitigating hunger. For others, it is securing food of sufficient quantity and quality for a decent life, a healthy life, or even a high quality of life. Still others widen the lens to include the welfare and rights of agricultural workers and farmers, the environment, or the well-being of nonhuman animals. And still others focus on protecting choice in the marketplace or on respecting cultural and national traditions and ways of life. The challenge for ethically acceptable global food security is to find a path forward, where tangible progress on ethical issues and disagreements in global food policy and practice is possible even in the absence of consensus about relevant values and permissible means.
