The United Nations sponsors the International Day for the Eradication of Poverty every year on October 17. The day seeks to recognizee the struggle of people living in poverty, give folks in poverty a chance to make their voices heard, and recognize that people living in poverty are the first to fight against poverty. This year's theme for the day is Children and Families Speak Out Against Poverty.
This Sunday is also the Children's Sabbath. Resources on the Decade of the Child webpage focus on fighting poverty for the welfare of children.
Children and those living in poverty are highly affected by issues arising from climate change. The National Council of Churches Eco-Justice Program has resources on Poverty and Climate Change and Climate Change and Children.
