Ibana: The adverse effects of climate change on human and non-human populations are irreparable.
With human populations mixing more and more freely with wild animal populations, the risk of rabies exposures increases.

For human populations and ecosystems to thrive, that water must be clean, it must stay clean and, most importantly, it must be accessible to all.

It may also be bad for people, so the group is now asking whether such effects can be detected in human populations.
Modern human populations grew, Neanderthal populations shrank, and the rest is prehistory.
Elephants have been known to breed at up to 5% a year, a rate which intensifies the risks of contact with growing human populations.
Those with alternative agendas may also try to use these new data to rank modern human populations in terms of supposedly different degrees of modernity.

In addition, little was known about the role that positive selection may have played in shaping the biology of human populations as they migrated and expanded.
These studies have been made possible by the growth in catalogues and maps of genetic variation among human populations, as well as differences with our closest relatives, such as Neanderthal and chimpanzee.
In the same issue of Science that included the Greenland research, scientists from NASA and Australia said that more detailed observations are needed to figure out what that will mean for human populations.
Moreover, our reliance on so few plants and animal breeds makes human populations that much more vulnerable to climate change: as growing conditions change, the most suitable species, breeds or strains in a given region may likewise change.

It would seem that the various tectonic collapses deep in the structure of our economic and political systems have triggered waves of kinetic energy which are rolling through human populations rather than through their usual medium of seawater.
While hundreds of studies around the world have linked climate change to phenomena including the increased frequency and intensity of hurricanes and other storms, changing rainfall patterns, drought, coastal flooding, changing disease patterns and the migration of human populations.
CNN: Environmentalists hope UN talks tough on climate change
Complicating the issue is the volcanic eruption of Toba, in Sumatra, around 74, 000 years ago, which injected so much sulfurous dust into the high atmosphere that it caused prolonged droughts that might have come close to wiping out many human populations.
WSJ: Matt Ridley on Early Humans Leaving Africa | Mind & Matter
While there has been a sizeable amount of research on human origins, with most evidence pointing toward an African genesis around 100, 000 years ago - the so-called "African Eve" - there is more and more interest in the patterns of relationship among existing human populations.
An international study found large hyena populations are living alongside human communities in Africa without coming into conflict.
Many older Africans vividly recall how their homeland was exploited by Western interests who failed to empower local populations, leading to widespread human suffering that still exists today.
Although researchers could find no link between the crash in cave bear populations and other factors, the event did "coincide with the start of human expansion, " commented co-author Dr Aurora Grandal-D'Anglade of the University of Coruna, Spain.
It is the scientific objectivity of genetic studies that gives it the power to say "at around this time, these people were here", freeing anthropologists to discuss the human developments - biological, societal, even political - that led populations to move and spread throughout the world.
Beyond improving human lives and the environment, public-private partnerships will create meaningful jobs for local populations.
FORBES: Presidential Candidates: Energy Diplomacy Key to Global Cooperation
European populations have mixed so extensively with their neighbours that their genes mirror geography, rather than reflecting the paths of human migrations or language families.
