Photochemical Smog

The other day I watched the news on TV that photochemical smog warning was alarmed in Yamaguchi prefecture and north the Kyushu district. That day was heat wave that the top temperature was above 35 ℃. Many elementary school was going to hold an athletic meeting that day. However because of photochemical smog, the meeting was put off. When I was pupil I was looking forward to going in for the athletic meeting. We should take care not to become the case and cooperate with ecology movement.
