What is the best uni for environmental science?

I just recieved offers from (yay) Manchester (BBB but I could get it reduced to BBC), York (BBB), Southampton (ABB), Sheffield (ABB) and Birmingham (AAB). I know that I dont want to go to UoB, but, from an objective standpoint, what uni is the best for environmental science?

Only you can answer that. Compare modules and optional modules for all years of the courses. Which interest you the most? Do any of the courses offer placement opportunities, which will add to graduate CV? Then think about which location suits you best by looking at accommodation costs and availability, transport links, entertainment, etc. Go to offer-holder days next year and don't make your decision until May (every year we see students on TSR decide their firm and insurance early and then regret it).
