Pollution

International catastrophes such as the wreck of the Amoco Cadiz oil tanker off the coast of Bryttanny in 1978 and the Bhofal Disater in 1984 have demonstrated the universality of such events and the scale on which efforts to address them needed to engage. The border less nature of atmosphere and oceans inevitably resulted in the implication of pollution on a planetary level with the issue of global warming. Most recently the term persistent organic pollutant (POP) has come to describe a group of chemicals such as PBDEs and PFCs among others. Though their effects remain somewhat less well understood owing to a lack of experimental data, they have been detected in various ecological habitats far removed from industrial activity such as the Arctic, demonstrating diffusion and bio accumulation after only a relatively brief period of widespread use.Growing evidence of local and global pollution and an increasingly informed public over time have given rise to environmentalism and the environmental movement, which generally seek to limit human impact on the environment.
