The world is not only hungry, it will also be thirsty for water. About 97% of water on the earth is sea water, or salty water. Man（人类） can only drink or use the other 3% of the fresh water which comes from rivers, lakes and underground.

The sea is very big. Look at the map of the world, there is more sea than land. It covers about three quarters of the earth, it looks very beautiful when the sun is shining on it. But it can be terrible when there is a strong wind.

The sea water is salty. There is one “sea” called the Dead Sea. The Dead Sea is not a sea. It’s a big lake in the Jordan Valley. It’s the saltiest lake in the world.  It’s near the city of Jericho. It’s about 80 kilometers long, between 4.8 and 17.7 kilometers wide. The river Jordan runs into the Dead Sea. Fish can’t live in the Dead Sea and plants can’t grow near it. People can’t swim well in the Dead Sea, but they can float （漂浮） on the water. The water is very blue and the air is clean. In winter, people come to the Dead Sea to enjoy the sunshine.
