A multitrillion dollar operation that seems ludicrously impractical, utterly unfathomable, and counter-intuitive to preservation of the environment? Is that what it's going to take to save our planet? Planting heat-resistance shrubbery in the Sahara Desert and parts of Australia will apparently impede the global warming process. So "if most of the Sahara and Australian outback were planted with fast-growing trees like eucalyptus, the forests could draw down about 8 billion tons of carbon a year--nearly as much as people emit from burning fossil fuels and forests today. As the forests matured, they could continue taking up this much carbon for decades." I think the desert animals that have become so adept at living in the inclement environments should be consulted as well, albeit this idea seems a little unfeasible.
