M T Vasudevan Nair

My entry into the world of Malayalam literature was through the masterful writings of M. T. Vasudevan Nair, whose passing today feels like a deeply personal loss. It was his novel Manju (Mist) that first drew me into this literary universe. The story, much like its title, was enveloped in an atmosphere of melancholy and mystery.

Elephant Migration

** The Escalating Conflict Between Humans and Elephants: An Analysis of the Impact of Climate Change** The increasing incidences of elephants encroaching into human settlements in search of water and food present a vivid manifestation of the broader environmental crisis fuelled by climate change. This essay explores the complexities of this escalating conflict, which not only threatens the survival of the majestic Asian and African elephant species but also poses significant risks to human communities. The fundamental issue at the heart of this conflict is habitat loss, driven largely by climatic fluctuations and exacerbated by human activities such as deforestation and the expansion of agricultural and urban areas. As natural forests dwindle and water sources dry up, elephants, which are known for their large home ranges and dependency on vast quantities of water, are forced to venture into human-dominated areas.
