There is a worldwide move to replace petrol-engine cars with electric cars.
Singapore needs to move with the times and go green as well.
One area we should relook is the Formula One race (Singapore to host F1 race for four more years; Sept 16).
As it is now, the race generates massive amounts of carbon and noise, and should be phased out.
We need to set an example and take concrete action against global warming to encourage our people and future generations to save the world.
