2. CAN we change? And the answer, fortunately, is now YES!
We’re seeing a continuing sharp, exponential decline in the cost of renewable energy, energy efficiency, batteries and storage  —  and the spread of sustainable agriculture and forestry  –  giving nations around the world a historic opportunity to embrace a sustainable future, based on a low carbon, hyper-efficient economy. Indeed, in many parts of the world, renewable energy is already cheaper than that of fossil fuels  —  and in many developing regions of the world, renewable energy is leapfrogging fossil fuels altogether  —  the same way mobile phones leap-frogged landline phones. And these dramatic cost reductions are continuing!
