Extreme air pollution kills about 175,000 people in Bangladesh every year. Not only that, but air pollution also increases the risk of non-communicable diseases such as lung cancer and other complex respiratory diseases. Vehicles emit 25% of the world's carbon, which is also accelerating climate change. Walking and cycling will reduce air and noise pollution, fuel consumption as well as traffic congestion and road accidents. At the same time, it is possible to meet the need for physical activity by walking, so the risk of non-communicable diseases will also be reduced. According to the Sustainable Urban Transportation Index of Dhaka city, school trips account for 17.7% of the total trips in the city. Significant changes in health and the environment are possible through this remarkable number of trips on foot and by bicycle. This was stated by the speakers at a human chain titled " We want a safe environment for walking to school to reduce non-communicable diseases " in front of Rupnagar Pilot School and College, Dhaka Ideal Cadet School, AstraZeneca and Work for a Better Bangladesh Trust on 11 November 2021 at 11.00 am.
