　　Crisis

　　Life is a contest! Who will win? A bluebird and sparrow both compete for

　　space to build their nests. A fast-growing maple tree and slower-growing dogwood

　　compete for the sunlight they both need. Oil competes with coal and nuclear power

　　as an energy source for electric power plants.

　　There is a problem. There is a limited amount of space for birds, sunlight

　　for trees, and energy for people! If we do not cut back on our uses of some of

　　our resources, someday they will be gone!

　　How can we use energy today and know we will have enough to go around in the

　　future? We can choose alternate, or replacement, energy resources. It takes the

　　earth millions of years to create coal, oil, and gas. They are nonrenewable

　　resources.

　　Solar energy, wind energy and water energy are renewable. What other ways can

　　we conserve our resources? How can we make sure there is always enough to go

　　around? (159 words)

　　America\'s Worst Surprise

　　December 7,1941 was one of the worst days in American history. Nearly all

　　Americans who are old enough to remember that day can still remember what they

　　were doing at the moment they heard "the news". The news was that America had

　　been attacked!

　　Shortly before 2:00 P.M., a radio dispatch came into Washington from

　　Honolulu, Hawaii, "Air Raid, Pearl Harbor— This is no drill." Japanese planes

　　had begun an attack on the largest American military base in the Pacific. They

　　first destroyed planes on the ground. Then they bombed the ships in the harbor.

　　No one had expected the attack. So no one was prepared for it. And it did not

　　take long for the Japanese to do their damage. When the smoke cleared, the Navy

　　counted its losses- Eighteen ships had been sunk or badly damaged. Nearly 150

　　planes had been destroyed. More than 2,400 Americans had been killed and more

　　than 1, 200 wounded. (157 words)
