Woo... Very informative! Thanks, i learned many important points. But friend one thing i want to get clear about is that as i said that its a topic of I.R (no doubt its even current affairs, everyday sci, essay topic aswell) but if we take it as I.R than how shall we relate it to the subject.. Are we even suppose to give the mechanism in detail (as we write for essay and EDS) even in I.R or we are suppose highlight the global concern here? If you notify my written than u may find that i have much focused on relating this topic to the subject i.e: world relation reasoning global warming. Will be thankful for the clearance n guide.
