the pictures symbolically illustrate pollution is becoming increasingly serious around the globe. In the first cartoon， a man is scorching the earth on a chimney. In the second one， a famous ancient Chinese poet， Wang Bo is astonished by the heavy smoke poured by chimneys into the air and dirty river polluted by a factory. We are informed that “the autumn river is the same color with the sky”。

the drawer is sending a message about the significance of the need for everyone to fight against the danger of environmental pollution. There is no denying that the industry is indications of civilization， proGREss and development. Unfortunately， as industry develops， so will the number of factories， and the amount of industry pollutants. We are so development-oriented that we almost can sacrifice our blue sky and pure water in order to obtain a little material gain.

As a consequence， it is imperative for us to take drastic actions. On the one hand， the factories should be equipped with devices which can dispose of waste gas and water so as to prevent them from polluting our planet. On the other hand， there should be an increasingly loud voice from the public for firm actions against poisonous gas sent off and unhealthy water polluted by factories.
