Poverty is defined as lacking material possessions or money needed to meet basic needs. Traditionally, most populations lived in poverty as production could not support comfortable standards of living. Major international organizations like the UN and World Bank aim to reduce poverty. Extreme poverty refers to lacking necessities like food, water, shelter and healthcare. Poverty is linked to widespread diseases and hunger, with millions of preventable deaths each year. Actions to address poverty include international anti-poverty days, government welfare programs with conditions, and work by non-profits.
