Today,I was watching the tv and I heard the bad news again...even I heard almost bad things or news in everyday...what a terrible and I feel so sad that killed people by people in nowadays...I can't understand which that's why people killed to someone,even all over the worlds become the worse than the past by people...why had human soiled and done for the earth...? We ought to do the earth-friendly things on the planet on which we live.And we must be help of each other for our life and the next generation.I sometimes learn about the earth..."Global Warming".I am very interested in it,so I search for it on the internet called "WWF",an environmental problem is taught to us about the exterminated animal,it's the pile which we should study about them....
