There are some easy things you can do to protect the environment and the earth. Choose ideas from the list or come up with a few of your own.
·Plant flowers, grass or trees.
·Whenever you visit a park or beach, take away what you bring there—keep rubbish in a bag until you can put it in a dustbin.
·Turn off the lights and TV sets when you leave the room. This can save a lot of electricity.
·Turn off the tap when you brush your teeth. You can save some water by not letting it run. Also, use a glass cup instead of a paper cup because this saves paper.
·Keep the doors and windows closed in winter to keep warm air in.
·Give your old books and magazines to a library instead of throwing them away.
·Give your old clothes to poor children you know instead of throwing them away.
·Use both sides of paper.

·Encourage all your friends to do the same things you do to help protect the earth. You don’t have to wait until Earth Day to do these things. Make every day Earth Day. If everyone makes a contribution to protecting the environment, the world will become much more beautiful.

Many places in the world need more fresh water. Every country is trying to find ways to turn salt water into fresh. Why aren’t there many factories like the Symi factory?
In some places the sun is not hot enough. Or it does not shine every day.
In such places other ways of heating sea water can be used. These ways cost more money, but they work faster than the sun. By boiling sea water with high heat a lot of fresh water can be made quickly.
But heating is not the only way to get fresh water from salt water. Other ways are tried.
One way is freezing. The fresh part of salt water freezes first. To get fresh water, the bits of ice are taken out.
Which way is the best? The one that gives the most water for the least money. It may be a different way for each place.
Symi’s way seems very good for small, hot places. It does not make much water at a time. But the factory is easy to build and costs little.
That is why people in many dry places talk about Symi.

Once there was a king who told some of his people to dig a pond (池子).The king then told his people that one person   15  each family had to bring a glass of milk during the night and put it into the pond. So, by the morning, the pond should be   16 of milk.
After   17 the order, everyone went home. As one man prepared his milk, he thought that since everyone was bringing milk, he would just   18 a glass of water and put that into the pond instead.   19 it was dark at night, no one would notice it, so he quickly went and put the water into the pond and 20  home.
In the morning, the king went to visit the pond. To his surprise, the pond was only filled with water! What happened? Yes! Everyone had the same idea   21  that man. They all thought, “I don’t have to waste my milk. Someone else will do it.”
Dear friends, when you plan to help poor people or people in trouble, do not think that   22  will take care of it. 23 , it starts with you. If you don’t do it, no one else will, so change yourself and make a   24  .

Right in the middle of the town are some long ponds(水池). They are only about half a foot deep. The men of Symi dug out the earth to make the ponds.
Over each pond is a low cover. It is made of glass that you can see through.
At night, sea water is taken into the ponds. The next day, the hot sun shines through the covers. The sun light turns the water into vapor(水蒸气) and the vapor goes up from the ponds. The salt is left behind.
As it goes, the vapor became mist. On the inside of each cover, the little drops of mist run together to make big drops. These drops run down the sides of the cover, filling other ponds with fresh water.
The salt left in the ponds is washed out each night. Then more sea water is taken in. The factory is ready for the next day’s work. The covers and other parts of the factory cost very little. Sea water and sun cost nothing. Most people of Symi are poor. So to them this new way of getting fresh water seems wonderful.
