Final answer:
Food insecurity refers to the lack of reliable access to sufficient, nutritious food, primarily due to poverty. Food security, which includes ensuring availability and access to adequate food for all, is still an unmet goal with millions globally affected by hunger.
Step-by-step explanation:
The term for a situation in which people have unreliable access to sufficient nourishing food is food insecurity. Food insecurity is a complex issue primarily driven by poverty, and it impairs the ability of people to have physical, social, and economic access to sufficient, safe, and nutritious food that meets their dietary needs for an active and healthy lifestyle. Factors contributing to food insecurity include income inequality, food deserts, and lack of food stability, which can be worsened by events such as natural disasters, economic downturns, and global pandemics.
Food security, on the other hand, is built on four pillars: availability, access, utilization, and stability. It ensures that all individuals have access to adequate food at all times. Unfortunately, despite global efforts to achieve zero hunger, projections show that we are not on track to reach this goal by 2030, with over 810 million people worldwide experiencing chronic hunger.
