You've got to be kidding, Japan wants to pump CO2 into the ground instead of releasing it into the air. In the ground, the chemical will not be filtered or used by plants to create more oxygen, instead, it will await an earthquake or some other major geological transformation, to explode into the atmosohere all at once. I've heard that it's rather hard to breathe Carbon Dioxide. If it all vented into the air at once, it would cover a huge area with unlivable conditions, am I right?
