The book virtually describe the beauty of nature with in the sphere of our civilization,i havent read it yet but i guess and very much determinated it is based with in the nature which is being getting polluted by the human species .i am from kashmir which is an occupied part of india we have had a large number of water bodies the cast famous is DAL LAKE which used ro be around 21 km² ,but as per its present data it has been shriked by 50% ,what ee believe is because of human behaviour dramatically changed .i want sir David to have some words in his speech that can make administration and common man resintage its original form or somehow make it stop for further pollute .
