When Theodore Roosevelt became president of the United States in 1901, he used the power of the federal government to support an important movement in the Progressive Era: the protection of America’s natural resources.
For most of the 1800s, moving westward and settling the nation’s western territory had been important to the growth of the United States. In that century, the nation seemed to have a limitless supply of natural resources. Large industries in lumber, mining, and hunting were established. Those businesses benefited from unchecked access to those resources. By the late 1800s, however, wasteful practices threatened to destroy the nation’s unique places and the wildlife and plants native to them. Environmentalists worried that the country’s natural spaces were disappearing.
As a sportsman who appreciated the wilderness, Roosevelt was greatly concerned. In May 1903, Roosevelt went camping for four days with John Muir in California’s Yosemite National Park. As they hiked and camped, the two men shared their ideas about America’s natural places.
Muir had spent decades living in and writing about the country’s unique wild places. He believed that people needed the wilderness to visit in order to renew their spirits. He wanted the land to be left alone, without any human interference. He called his plan “preservation.”

Eye in the Sky
An interview with Joe Piotrowski
Airborne Animals
Humans have taken to the skies in balloons, gliders, and airplanes-but we're not alone among the clouds. Animals of all sorts have evolved to harness wind power.
TAKING OFF
The Wright brothers expected airplanes to “take off,” but even they might be amazed at the way the airline industry has become big business. In the past, it was expensive to send something by plane.
GROWTH OF AN INDUSTRY
After their historic flight at Kitty Hawk in 1903, Wilbur and Orville Wright returned to Dayton, Ohio. They spent the next few years making adjustments and building additional versions of their powered aircraft in their bicycle shop.
WHY KITTY HAWK?
The Wright brothers searched carefully for the best place to test their gliders and flying machines. Their main concern was for good, steady winds. But they also hoped to find a remote location to allow them to perform tests away from the public eye.
Two Brothers From Ohio
Most people do not realize that the Wright brothers—Wilbur, born in 1867, and Orville, born in 1871—performed various scientific experiments before inventing their aircraft. For as long as anyone in their hometown of Dayton, Ohio, could remember, the Wright boys had worked on mechanical projects.
A Helping Hand
May 6, 1896. A group of people who had gathered beside the Potomac River, just south of the U.S. capital, grew quiet. Then, it erupted in cheers as a small, unmanned aircraft took to the skies and flew for more than half a mile. The flight came seven years before the Wright brothers’ first manned, powered flight. The inventor of the aircraft was Dr. Samuel Pierpont Langley.
THE IDEA MEN
People dreamed of flying thousands of years before the Wright brothers found success near Kitty Hawk, North Carolina. These dreamers, such as Leonardo da Vinci, studied birds flying and imagined how humans might do the same—if only they had wings. Other men developed a more hands-on approach to the topic. Early inventors made wings of cloth, glue, and feathers and tied these creations to their arms in an attempt to imitate nature.
Da Vinci's 4 Designs
Have you ever wondered how a bird flies? Leonardo da Vinci (1452–1519) did. He thought that understanding how a bird flies would provide the key to human flight. So, what did da Vinci learn from birds?
Silken Wings
Seven hundred years before the Wright brothers began experimenting with human flight, the Chinese had already mastered its secrets—with kites.
