2. ANTHROPOCENE

3. The Anthropocene Epoch is an unofficial unit of geologic time, used to describe the most recent period in Earth’s history when human activity started to have a significant impact on the planet’s climate and ecosystems. As of April 2022, neither the International Commission on Stratigraphy (ICS) nor the International Union of Geological Sciences (IUGS) has officially approved the term as a recognised subdivision of geologic time .

4. The Trinity test in July 1945 has been proposed as the start of the Anthropocene .

5. Climate Change

6. GUANO IMPERIALISM

7. METABOLIC RIFT Metabolic rift is the "irreparable rift in the interdependent process of social metabolism “. The concept of the metabolic rift is a useful lens to understand the underlying socio-environmental injustices in the climate crisis in India. We understand the metabolic rift in India through the assemblage of land and intersectional inequalities. The analysis of the climate crisis remains limited or even flawed if land politics and land-based social inequalities are not centre staged in the enquiries of the climate crisis.

10. Zoonoses

11. “A Pacific Island Nation Is Stripped of Everything ”, NY Times, 10.12.1995 Inch for inch, Nauru is the most environmentally ravaged nation on earth … the environmental devastation of Nauru is nearly total. Four-fifths of the island has been mined out , leaving behind a pitted, ghostly moonscape of gray limestone pinnacles, some as tall as 75 feet … The waves of heat that rise from the mined-out plateau drive away rain clouds, leaving the sun-baked island plagued by constant drought ... Environmentalists say it is unlikely that the land will ever produce enough food to feed the population .

12. Effect of Monoculture

13. “Agricultural land-uses consistently exacerbate infectious disease risks in Southeast Asia”, Nature , 20 Sptember , 2019, pp. 1-13 Oil palm, rubber plantation and rice paddy monocultures have reduced species richness compared with primary and secondary forests, and these monocultures are structurally less complex than natural forests typically exhibiting a more uniform age structure, lower or no canopy, sparse undergrowth, less stable and more extreme microclimates … biodiversity loss itself could favour disease carrying hosts or vectors or increase the efficacy of disease transmission to remaining hosts
