2015青岛一模Recently, smog weather has became more and more serious in parts of China. People forced to wear masks to avoid breathe poisonous air. To settle this problem, the series of measures should be taken. First, we should enact more strict law on environmental protection to regulate the industrial production and punish those factories what ignore the protection.Second, we should develop environmentally-friendly products to improve air quality.
