Today in Singapore, air pollution from a combination of vehicle emissions, dirty industries and urbanisation is visible right outside your window. The hazy appearance is a result of the sun's reflection off tiny particles in the polluted air. These particles cause irritation to the lungs and throat. As an added bonus, the cumulative effects of long term exposure shortens your life span.

Moreover, the presence of many hi rise buildings reduce wind speeds inside the country exacerbates the situation. Inter-boundary air pollution from heavy industrial and shipping activity from neighbouring countries does not help either.

Three prong approach to reduce pollution:
1) Less fossil fuel based vehicles on the road, use electric vehicles.
2) Less hi-rise buildings.
3) Less reliance on heavy industries and manufacturing plants as economic drivers.
