Hello Damascus;
Dr. Ehrlich gives a very interesting view from his 1968 book, The Population Bomb to the reduced population in America or the world is experiencing in these times. Through the decades it's not fair to say Dr. Ehrlich's in-depth was entirely wrong. As he said, America has headed in a troubling direction for many reasons, health, immigration, the trends of sinful lifestyle to the unbeliever, the pandemic, etc...
He is not a prophet and God has the final say so on His creation. But I can keep an open heart as Dr. Ehrlich "did and does" still give an interesting view on the study of population.
God bless you, Damascus, and thank you for sharing this article.
