cut its CO ₂
emissions by using more
methane produced by hydrofracking; that the rest
of the world will soon follow USA's example to significantly expand dependence on
methane via hydrofracking.
Various Updates In a move that environmental campaigners had sought for years (as had I), the Environmental Protection Agency has issued final rules that could substantially
