paul ralph ehrlich -lrb- born may 29 , 1932 -rrb- is an american ecologist and demographer , best known for his dire warnings about population growth and limited resources .
he is the bing professor of population studies in the department of biological sciences at stanford university and president of stanford 's center for conservation biology .
ehrlich became well known for his controversial 1968 book `` the population bomb '' , which asserted that the world 's human population would soon increase to the point where mass starvation ensued .
among the measures he suggested in that book was population control , to be used in his opinion if voluntary methods were to fail .
ehrlich has been criticized for his views ; for example , ronald bailey called ehrlich an irrepressible doomster .
on the other hand , carl haub observed that ehrlich 's warnings had encouraged countries to take action to avert disaster .
ehrlich has acknowledged that some of what he had written had not come about , but has restated his view that over-population remains a major problem .
