| After defining war, the author moves on to the effects of war on
                environment. In this context, he points at the environmental
                devastation caused by the war in Vietnam and then in the Gulf
                region. Herbicides were used to destroy vast forest and crop
                areas in Vietnam. Clouds of smoke from burning oil wells in
                Kuwait blacked out the sun and lowered surface temperatures in
                many areas. Oil spills destroyed a large part of the marine life
                in the Gulf.
 The book points
                out that even in peace time the military’s demands on land and
                resources have increased for testing missiles and other weapons
                which need large areas of land and even sea. If war wrecks the
                infrastructure of civilisations, as it did in Vietnam,
                Afghanistan and Iraq, the post-war effects are no less tragic.
                Unexploded mines, bombs, shells, rockets and grenades often
                cause disastrous accidents. The book also
                discusses the effects of an unconventional war on the
                environment and classifies such warfare into four categories —
                nuclear, chemical, biological and environmental. A nuclear
                exchange between any two countries, the author points out, will
                result in global economic and social disruption apart from the
                colossal damage caused to the contestants. The substances
                used in chemical warfare may be poisonous, blistering or having
                an irritant effect. The author draws a parallel between the
                testing of chemical weapons and the Bhopal gas tragedy, which
                took nearly 2500 lives and left more than 100,000 severely
                affected. The similarity between the Bhopal tragedy and the use
                of chemical weapons on a civilian population was so striking
                that many have gone to the extent of suggesting that the
                disaster was a planned experiment in chemical warfare, the
                author points out. About biological
                warfare, the book lists about a dozen highly virulent species of
                bacteria that are very suitable for this type of warfare in
                which toxic biological substances are employed to cause
                casualties. Environmental weapons such as fire and flood have
                been used since ancient times. Others are only possibilities for
                the future. The book contains
                an indictment of the Gulf War of 1991 as an environmental crime.
                It also contains a chapter on disarmament in the context of
                environmental security. The formation of an ecological task
                force of ex-servicemen for the protection of India’s ‘green
                belts’ constitutes the concluding chapter. Char Dham, a
                Guide to the Hindu Pilgrimagesby Subhadra Sen Gupta.

 Pilgrimage is the most ancient
                form of tourism. For centuries the devout have travelled across
                difficult terrains to reach their sacred shrines. Countless
                Hindus have crossed remote Himalayan peaks and treacherous
                glaciers, braving cold, altitude sickness and frostbite to reach
                Mount Kailash and the Mansarovar lake. Millions have undertaken
                long and arduous journeys across perilous hill tracks and sandy
                deserts to reach remote shrines. The most famous
                Hindu pilgrim was Shankracharya who began his journey as a
                teenager from Kerala, travelled to almost every important tirtha,
                and played a significant role in the revival of Hinduism as the
                principal faith of the land by setting up monastic orders called
                maths at the four dhams. The four dhams,
                described in this book by a well-known scholar of Hindus
                cultures, are believed to be the abodes of Vishnu and are
                located in the north, south, east and west of the country. In
                the north is Badrinath in the Himalayas, where Vishnu bathes in
                the Alakhnanda. He gets dressed at Dwarka beside the Arabian
                Sea, eats a meal at Puri on the shores of the Bay of Bengal and
                proceeds to Rameshwaram where the Indian Ocean washes the
                southernmost point of the sub-continent, for a well-deserved
                rest after performing the arduous task of preserving the
                creation. In addition to
                narrating legends connected with the four dhams, the book
                also describes other sacred places around each dham and
                the legends connected with them. For the benefit of today’s
                travellers, there is a chapter appended to each dham detailing
                the best time to visit the place, the mode of travel and other
                facilities available there.
