Paul Ehrlich, Professor of Biology, Stanford University, Ann Ehrlich, author of books on over population and ecology, John Holdren, American scientist who served as the senior advisor to President Barack Obama on science and technology issues: What have these three done that is ehrlich science for people everywhere?

Ehrlich argued that, “if the population control measures are not initiated immediately, and effectively, all the technology man can bring to bear will not fend off the misery to come.” In 1973 Holdren encouraged a decline in fertility to well below replacement in the United States, because “210 million now is too many and 280 million in 2040 is likely to be much too many.” Please use the enlarge slide bar to read.
