An inconvenient truth

I`m just watching over the movie "An iconvenient truth" The main actor, the ex-vice president, Gore said something that we must face. It really occurs me. I have to take it serious so that we can help this world. Maybe the green economics is the part I want to know. The movie said there are a old adage in Africa "Prey on your feet."(I don`t remember if it is. Anyway, It`s that mean.) I hope and I will do.
