What percent of the human population does not have access to adequate food and water while another part of the population is overfed and wasteful?

As of recent estimates, about 9% of the global population—approximately 690 million people—lack access to adequate food, while a significant portion of the population experiences overnutrition and food waste. It's estimated that around one-third of all food produced is wasted, highlighting the stark contrast between food insecurity and overconsumption. This disparity illustrates the unequal distribution of resources and the need for more sustainable food systems.
