Pollution: An Increasing Concern in China
It is reported that ten big cities in China are being ranked among the top twenty cities with the highest pollution index in the world. This means it is high time we did something to bring the situation under control.
Many factors are contributing to the deteriorating situation: industrial wastes pumped into the air, the lakes and rivers; a increasing number of automobiles crowding into the streets; the widespread use of plastic bags etc.
To my view, stiffer laws and regulations must be implemented to check pollution. Industries that release wastes without permission should be heavily fined. Cars should be equipped to minimize the exhaust they release into the air. And the use of plastic bags and disposable meal boxes should be banned. Whats more, the media should play an important role in implanting a sense of environmental consciousness into peoples mind.
If everybody works toward a common goal of making the environment better, we can create a cleaner and lovelier world for us and for the coming generation.
