Greenhouse Effect - To .. or not to ?

We keep hearing about "Greenhouse Gas" emissions and stuff... but what are they really ? How does it impact our lives ? our Planet ? our community ? Greenhouse is the result of technology , in layman's term we are inside a "giant naturally made oven" scarry huh ?That's the truth , I found this very interesting website that got me thinkin' what if I want to design my future house thats greehouse friendly ? hmmmm solar panels ? That could save electricity. Cool cars running on bio diesel fuel , i would prefer cars that runs with water !
