to people’s health. Terrible
happen every now and then. Some freeways are shut down because of the low visibility (能见度). In Nanjing, schools had to close because of the hazy weather last December.
Obviously, air pollution is the ( cause that has resulted in (导致) the terrible weather. People don’t pay much attention to the environment, so the
between nature and human beings is lost.
People have started to consider how to protect on hazy days. They try to avoid outdoor activities and wear expensive masks to
away from haze while going out. But actually, no one can really keep away from it
they wear masks or stay inside. Haze is everywhere around the city.
Haze is a warning. It warns us to take action to make our Earth a better place. If Earth is too for us to live on, what should we do? Maybe we have to be
on Mars.
