Environmental sciences, encompassing ecology, agriculture, geography, soil culture, forestry, marine science and botany is a multi-disciplinary subject. With the sharp declining/ deteriorating conditions "Environment and ecology" gained prime importance and currently is a widely debated issue.The movement for the protection of forests and wildlife is strong in India. Legislative measures have declared certain animals protected species, and areas with particularly rich floral diversity have been adopted as biosphere reserves. Virtually no forests are left in private hands. Projects likely to cause ccologiral damage must be cleared by the Ministry of the Environment and Forests. Despite such measures, the reduced acreage ot forests, savanna, and grasslands provides little hope that India's population of animals can be restored to what it was at the end of the 19th century.Encyclopaedic in nature and organised in two volumes, this work contains highly useful and reliable information on all major issues pertaining to the theme.
