John Muir, also known as the ‘Father of National Parks’, was a famous American conservationist, writer, naturalist and explorer, who promoted the conservation of wildlife in the United States of America and around the world. His books and essays narrate his personal experiences with nature and encourage people to support his cause of preserving the environment. Millions of his books were sold around the world and his fervent activism has helped in the preservation of the Sequoia National Park and the Yosemite Valley. He also founded the ‘Sierra Club’, which to date is one of the most important conservation organizations in the United States of America. Towards the end of his life, he devoted most of his time in efforts towards safeguarding the Western forests and even implored the U.S. Congress to help pass the National Park Bill. Along with the support of politicians, leaders and congressmen, he mobilized opinions to help preserve enormous wildlife areas. His writings are frequently discussed by a number of modern day conservationists today and inspire countless individuals who are looking to follow his footsteps.
