Save This Land discusses some topical issues of the environment. In each of the six chapters, a topic is chosen, the problem is analysed, the dangers are described and the solutions are presented with an appeal to all for proaction to save this land. The imminent desertification caused by deforestation of land, amply served by the monsoon, must be averted by the construction of hundreds of thousands of micro-dams. The threat of sea level rise needs to be combated by undertaking a massive project of Coastal Works. The Ganga could remain perennial only with significant reforestation and strengthening of lateral and terminal moraines in the Himalaya. "When rivers die, civilisations die," and this land faces an existential crisis because of the rivers choked to death by a vast deposition of sediments that need to be excavated for their revival. The Hirakud Dam on the Mahanadi must be revived too. Bodies of good clean drinking water are the heritage of humanity and they are getting polluted. The water quality is paramount and must be maintained.
