Environment is an important topic that more and more people are concerned about it. It is necessary to protect our environment because it helps keep us from suffering any disasters in the nature.
China dust storms is a seasonal meteorological phenomenon which affects much of East Asia sporadically during the springtime months.The air quality will become rather terrible with the sand storm.

How to protect our environment? Many scientists have been discussing this topic all over the world. In my opinion, we need to care about wild life and our natural resource. Some people keep hunting wild animals and killing them for food and clothes. At the same time, our human being have been affected by these wild animals' diseases. Businessmen keep their industries develop so that many pollutants have been released to the air and water. The pollution does seriously harm to our normal lives. On the other hand, we need to save our water. I often see people waste a lot of water every day. They don't know that our natural resources are so limited with huge growing population.
The government has begun to take measures to fight against pollution.But there is still a long way to go.We should take care of our earth and try our best to protect it,not only for ourseves.
In conclusion, protecting our environment needs everyboy to take responsibility. Let us do it from now on to create our healthy living environment.

Answer 2

A dust storm or sandstorm is a meteorological phenomenon common in arid and semi-arid regions. Dust storms arise when a gust front blows loose sand and dust from a dry surface. Particles are transported by saltation and suspension, causing soil erosion from one place and deposition in another. The Sahara and drylands around the Arabian peninsula are the main source of airborne dust, with some contributions from Iran, Pakistan and India into the Arabian Sea, and China's storms deposit dust in the Pacific. It has been argued that recently, poor management of the Earth's drylands, such as neglecting the fallow system, are increasing dust storms from desert margins and changing both the local and global climate, and also impacting local economies.

The term sandstorm is used most often in the context of desert sandstorms, especially in the Sahara, or places where sand is a more prevalent soil type than dirt or rock, when, in addition to fine particles obscuring visibility, a considerable amount of larger sand particles are blown closer to the surface. The term dust storm is more likely to be used when finer particles are blown long distances, especially when the dust storm affects urban areas.
