　　LESSON 157 THE NUCLEAR GENE1: WHAT NOW?
The Oak Ridge2 Laboratories were at one time the nucleus3 of the American nuclear program. Splitting the atom at that time was a novel idea: all you had to do was to get a mass of uranium nuclei4 together, and you got a reaction. How much of a reaction depended on the number of nuclei you put together. Numerous tests were carried out over the years just to see what would happen when and how, because everyone involved was just a novice6 at what they were doing. As it was wartime, the initial work was top secret, and everyone involved had to take an oath of secrecy7 and obedience8.
By now, the novelty has worn off, to say the least. Nowadays, it is well known that a great many noxious9 substances are released during nuclear reactions. More than that, any serious nuclear exchange could send most of mankind to oblivion, rendering10 all the achievements of human civilization over many thousands of years null and void. The very thought of such an eventuality is enough to make any sensitive human being feel quite numb5 and helpless.
A film was made some years ago about exactly what would happen. It turns out that Australia would probably be the last oasis11 left capable of sustaining human life. There are plenty of nutrients13 in Australia’s rich soil, as well as plants of high nutritional14 value to provide sufficient nutriment for the animals needed to be reared to feed the last stragglers of the human race. Of course, those sheep and cows would need to be carefully nurtured16 before they could ever be turned into nutritious17 steaks. No problem, I think, people would have plenty of time on their hands.
