The earth is our home.In order to protect them,something must
be done.
Save water. Man can't live without water.So it's very important
for us to do so. We should not only protect drinking water and
stop polluting it, but also make full use of it.
Save electricity（电）. We can't imagine what the life will be
like without it. Everyone should do his best to save electricity.
Don't forget to turn off lights or other electric machines when we
finish working.
Save forests. Please stop cutting them down and use recycled
paper instead. Make our world a green one to live in.
Recycle （再循环）useful rubbish. Plenty of rubbish can be
recycled like paper, bottles, and so on. We can save resources
(资源）in this way.

her, and make our home more beautiful.What should we do to protect our earth? Where there is green, where there is life.What should we do to protect our earth? Saving the Earth How to protect the environment becomes one
of the biggest problems in the world. We can find the rubbish
