Question

Our earth is in trouble.  Our drinking water is becoming dirtier, and the air is not as clean as before.  People and factories are polluting the air, rivers and lakes and seas.  You may think that there is mothing you can do to help.  That’s not true.  There are many things you can do to help the earth.
Cars burn gasoline.  This will produce a lot of CO₂ into the air.  Some people believe that too much CO₂ is making the earth warmer than ever.  They think CO₂ thins the clouds above us.  The clouds keep us away from the strongest sunlight.  So try to walk, ride a bike or take a bus.  And if you drive a car, drive at a steady speed.  This can save some gasoline.
The biggest energy use at home is for keeping warm and cool.  So turn the air conditioner off when you don’t need to use it.  Use lights that save energy.
Use fewer things that cannot be used again.  When you buy something, consider those made from things that can be used again first.
（1）要用大量的水來洗澡沐浴。In one week an American family uses as much water for showers as a person drinks in three years! Buy a waterworks that uses less water, or take shorter showers.  This can cut the use of water.
