Chronic hunger is defined as a lack of access to enough safe and nutritious food that prevents normal growth and development. It affects over 926 million people worldwide and is caused by factors like poverty, conflict, and natural disasters rather than a global lack of food. Chronic hunger has particularly severe consequences for children, weakening their immune systems and stunting their development through malnutrition. The document encourages signing a petition and participating in fundraising efforts to combat chronic hunger during the week of November 1-5.
