Endangered river dolphin
Human interference has altered for worse eco-systems in every corner of the globe. Ironically, scientific developments have hastened its deleterious impact, with faunal and floral species bearing the brunt of man's rapacity and capacity to destroy. The number of endangered species in the Red Data Book of the International Union for Conservation of Nature and Natural Resources has increased each year. Nowhere is this as tellingly visible as in Assam, once described by naturalists as a paradise for wild-life.
