Arguably the greatest concern humans face over the next 100 years is how climate change, the deterioration of our planet’s environment and increasing world population will affect the health and well-being of children. The greatest impacts are likely to be on respiratory health due to worsening air quality and increases in respiratory infections. Current climate change initiatives will be futile if present population increases continue. This session will present the latest projections of relationships between climate change, environmental threats and increasing population how these will affect the future respiratory health of children. Advocacy strategies addressing these issues will be discussed.
