Human-dominated marine ecosystems are experiencing accelerating loss of populations and species, with largely unknown consequences. We analyzed local experiments, long-term regional time series, and global fisheries data to test how biodiversity loss affects marine ecosystem services across temporal and spatial scales. Overall, rates of resource collapse increased and recovery potential, stability, and water quality decreased exponentially with declining diversity. Restoration of biodiversity, in contrast, increased productivity fourfold and decreased variability by 21%, on average.

Global environmental change (GEC) is among the most severe challenges facing mankind today. It is a suite of environmental change problems, climate change being the most studied of all. Global environment includes physical, chemical, and biological processes that are necessary for life-supporting services on the earth. No studies on a single environmental component will be meaningful for GEC, if viewed in isolation. It is the feedback between various components that assumes greater importance for GEC and, hence, the term GEC involves changes in various components of the environment.

Considering the increasing urban population and the resulting urban liquid waste, an attempt has been made to ascertain the quality of the Pondicherry coastal water. Four sampling stations-two on the 1 fathom line and two on the 5 fathom line were fixed. The results revealed that the total coliform bacterial population showed seasonal variation viz. between post and pre-monsoon periods.

A globalising world requires multilateralism to attain shared goals particularly the preservation of ecological security. While this can happen without the leadership of one country, citizens of the world increasingly look to the US for leadership in ad
