Diwali, the festival of lights, is being celebrated with less noise and smoke this year.

According to Indian newspaper The Economic Times, higher prices and school campaigns have dampened sales of fireworks. Shop owners have said it's the worst Diwali for them, with sales of fireworks down 60 percent, because of rising awareness of the pollution caused by fireworks.

Schools have been educating students about the noise and air pollution caused by fireworks, and the government has also been running public awareness campaigns, causing this year's Diwali celebrations to be a little less bright and loud.
