Explanation:

Aldo Leopold (January 11, 1887 – April 21, 1948) was an American creator, savant, researcher, biologist, forester, progressive, and tree hugger. He was a teacher at the University of Wisconsin and is most popular for his book A Sand County Almanac (1949), which has sold in excess of 2,000,000 duplicates.  

Leopold was powerful in the advancement of present day ecological morals and in the development for wild preservation. His morals of nature and untamed life protection profoundly affected the ecological development, with his ecocentric or all encompassing morals in regards to land. He underscored biodiversity and biology and was an originator of the study of natural life management.
