"The environment is experiencing tremendous problems at the moment, and one of the most serious of these is that we are losing our oxygen. The oxygen content of the air is becoming so low that it threatens our very existence in some areas. The normal oxygen content of our air is 21 percent. But in some places it is only a fraction of that! In Tokyo, Japan, for example, the oxygen content of the air has dipped to 6 or 7 percent. If it reaches 5 percent, people will begin to die. Tokyo has even put oxygen disbursement centers on its street corners, so that people can get emergency oxygen if they need it."
