I think it is real, and we are partially responsible. But even if it isnt real, and all this is a hoax, I am glad that it happened because it has made the world feel like a whole, so its bought us closer together and thats always good since we all share the planet. Its also made the public more aware of taking care of the planet, not just in ways that reduce green house gases. Water conservation and deforestation are all looked at. So I like the whole package the media (and i dont just mean cinimatic realeses, I mean magazines, newspapers, tv and radio etc) has flooded us with.
In the end we ended up helping the planet and be less greedy.
