The author like any good economist sitting in a comfortable chair , is playing with numbers like counting and manipulating alphabets in alphabet soup. He uses too many IFFs too! This is not reality of life on the ground! Zero carbon economy can NOT be achieved unless the runaway population is not halted. To put it bluntly, countries with declining populations should thank the Lord, for runaway populations demand heat and cold, minimum qty. of food for better life. It also produces sickening pollution, corruption, criminality , break down in law etc. negating every bit of progress.



What is missing in this big equation is political will to solve the problem before it is too late!
