An Inconvenient Truth

After watching part of 'An Inconvenient Truth',I feel that we really must do something,even if we cannot reverse global warming.But tat is not a reason to say "Oh,since we cannot stop it,then I cannoy do anything."or anything like that.We can still try to slow it down and maybe then it will stop.One way is to cut down on the use of cars and take public transport instead.And if you really need to use or buy one,go for a hybrid.
