Science Homework Help

I don’t understand this Ecology question and need help to study.

Aldo Leopold was a world-renowned ecologist who published extensively in highly ranked academic journals. Why was his lasting contribution to the field of ecology seen as this small little book, A Sand County Almanac? What is it about, A Sand County Almanac, that caused it to become one of the most popular books ever written in the world? Integrate specific examples from assigned reading, Part I of the book, A Sand County Almanac in your response.
