Look carefully at the back of a California state quarter．A man with a walking stick is pictured there．A bird called a California condor （大秃鹫） is flying overhead．Who is this man，and why is he so important that he is featured （处于显著地位） on the back of a coin？
The man on this quarter is John Muir．Even as a child，Muir loved watching nature．As a young man，he spent much of his life exploring the beauty of the wilderness．He walked more than a thousand miles across the country，through fields and woods．John Muir liked writing about the places he visited，describing their beauty．
Muir also wrote about problems．In order to create more farmland for sheep and cattle，many trees were being cut down．This made Muir unhappy and worried，because he knew that trees were important to forests and to the animals that lived in them．
Muir believed that nature should be conserved （保护） instead of being changed by human beings．He wrote articles in magazines and newspapers to spread the words about conserving forests．Soon，others began to listen．Muir wrote letters to important people，such as President Theodore Roosevelt．The president admired Muir's love for nature．When Roosevelt came to visit Muir in California．Muir convinced （说服） the president to go camping with him for three nights under the trees so they could talk about conservation．Later，President Roosevelt set aside 148million acres of land for national forests and established （建立） five national parks． National parks are large areas of land that are protected from development．This means that people cannot build homes or businesses there．One of these parks is Yosemite National Park，the area that is featured on the back of the California quarter．
Though it has been almost one hundred years since John Muir died，people continue his work today．His work as a conservationist helped us to see the beauty of our natural world．John Muir made us understand the importance of protecting our earth and our resources-then，now，and for the future．
