The document emphasizes the integral role of children in sustainable development, asserting that their health, education, and well-being are foundational for future societal progress. It presents three key messages: sustainable development begins with well-nurtured children, safe societies are crucial for child development, and children must be active participants in shaping their future. The call to action urges decision-makers to prioritize children's rights and needs in the post-2015 development agenda to ensure a healthy, equitable world for all generations.
