Journal ArticleDOI
Butterflies and plants: a study in coevolution
Paul R. Ehrlich,Peter H. Raven +1 more
TL;DR: The relationship between butterflies and their food plants is investigated, the examination of patterns of interaction between two major groups of organisms with a close and evident ecological relationship, such as plants and herbivores.
Journal ArticleDOI
Accelerated modern human-induced species losses: Entering the sixth mass extinction
Gerardo Ceballos,Paul R. Ehrlich,Anthony D. Barnosky,Andrés García,Robert M. Pringle,Todd M. Palmer +5 more
TL;DR: Estimates of extinction rates reveal an exceptionally rapid loss of biodiversity over the last few centuries, indicating that a sixth mass extinction is already under way and a window of opportunity is rapidly closing.
Journal ArticleDOI
Impact of Population Growth
Paul R. Ehrlich,John P. Holdren +1 more
TL;DR: In this paper, the authors argue that population growth causes a disproportionate negative impact on the environment and that the control of population is necessary but not sufficient means of seeing us through the whole crisis of environmental deterioration.
Book
The Population Bomb
TL;DR: Finally with characteristic myopia those breathing a sigh of relief at the prospect of "only" 280 million Americans by 2000 AD neglect to consider what will happen in the early years of the next century as their children struggle to survive for even with luck we are doomed to continued population growth until at least 2045 and the projected population size then will be over three hundred million as discussed by the authors.
Journal ArticleDOI
Biological annihilation via the ongoing sixth mass extinction signaled by vertebrate population losses and declines
TL;DR: The population extinction pulse shows, from a quantitative viewpoint, that Earth’s sixth mass extinction is more severe than perceived when looking exclusively at species extinctions and humanity needs to address anthropogenic population extirpation and decimation immediately.
