Nutritious food is a basic necessity of life, and failure to obtain sufficient calories, macronutrients (fats, proteins, carbohydrates), and micronutrients (vitamins, minerals) can result in illness and death. While malnutrition and hunger are typically problems in the developing world, the United States and other developed countries still have significant populations affected by insufficient food resources and under-nutrition. Nourishment can likewise be a source of foodborne ailments, coming about because of eating ruined sustenance or nourishment sullied with organisms, synthetic buildups or dangerous substances. The potential effects of climate change on foodborne illness, nutrition, and security are mostly indirect, but on a global scale, can result in large numbers of populations affected.
