I remember this song I was 10 years old in 1969. It was both frightening and enlightening. Now in 2021 I feel Zager and Evans were generous in giving the human race 10000 years to turn itself around. War, pollution, overpopulation, disease and confusion will win the race against mankind much sooner. Nature is the master of this world. She is generous and graceful but she has and will eliminate any species at any time. Knowing this and slowly responding through 50 years, we only care for what we can have now, we are the only ones that matter. We can pray to God and he will help but he will not solve our problems for us .
