Every thinking person (and their dog) knows by now that the World is in the grips of a terrible malady. This is the greenhouse catastrophe and, regardless as to the major cause, we know that it is happening and threatens us and every other species of life.
We also are unavoidably aware that we must drastically reduce the emission of heat and CO2 in order to save our planet from a terminal degradation which will involve huge painful death to billions of people.
Up till now, the answer from the people in charge has been,"No way, this would be impossible to accomplish." However, in the space of a short few months, the world has demonstrated that this is not impossible, but quite to the contrary.
Undeniably, we would suffer much in the permanent conversion to a new economy. Our expectations will be trimmed, in some cases hugely. But life as we know it would continue and may become less stressful and more rewarding, knowing that the future had more to offer. It is worthwhile to think on this I think.
