Historical prevalence of HIV-1 subtypes The earliest known cases of human HIV infection have been linked to western equatorial Africa, probably in southeast Cameroon where groups of the central common chimpanzee live. The hunters then became infected with HIV and passed on the disease to other humans through bodily fluid contamination.
Fishing fleets are 40 percent larger than the ocean can sustain. Sincethe global economy has tripled in size and population has grown by 30 percent to 6 billion people. The analsysis, by the World Resources Institute WRI warns that if the decline continues it could have devastating implications for human development and the welfare of all species.
The analysis examined coastal, forest, grassland, and freshwater and agricultural ecosystems. The health of the each ecosystem was measured, as based on its ability to produce the goods and services that the world currently relies on.
To make matters worse, as our ecosystems decline, we are also racing against time since scientists lack baseline knowledge needed to properly determine the conditions of such systems.
The four-fold increase in humans and the advent of the consumer society - have made the end of the millennium a cusp of history. Affluent consumers in Hong Kong want exotic fish and presto!
Poachers in the Philippines destroy vital reefs to meet that demand. Millions of workers in China and Russia are plagued with pollution-related ailments.
We need your help to ask President Barack Obama and the Environmental Protection Agency to get working on a bold plan to curb ocean acidification. Carbon dioxide pollution is also being absorbed by the ocean, causing its chemistry to change and become more acidic.
This spells trouble for marine animals that are now having difficulty building shells, growing and sometimes even surviving in increasingly corrosive waters.
Damian Carrington Seafood is the critical source of protein for more than 2. Official catch data from FAO rarely includes small-scale, sport or illegal fishing and does not count fish discarded at sea.
A more exhaustive study, taking over a decade shows that the annual catches between and were much bigger than thought, but that the decline after the peak year of was much faster than official figures. The new research estimates the peak catch was million tons, but declined at 1.
Prof Daniel Pauly, at the University of British Columbia in Canada and who led the work, said the decline is very strong and "is due to countries having fished too much and having exhausted one fishery after another. While the results necessarily remain uncertain, they undoubtedly represent our most complete picture yet of the global state of fish catches.
But afterfew undiscovered fisheries were left and catches started to decline.
The decline since has largely been in fish caught by industrial fleets and to a lesser extent a cut in the number of unwanted fish discarded at sea. On resumption, catches were bigger than ever.
We know how to fix this problem but whether we do it or not depends on conditions that are difficult.
Illegal and pirate fishing take place in many parts of the world. We can also see, that in efforts to stem declines, we have been using more and more bycatch that was once thrown away. Jeremy Hance Seabirds have been around for sixty million years, and they are true survivalists: But now seabirds seabird abundance has dropped Edd Hammill with Utah State University and co-author of the paper, noted:Addressing the bushmeat trade requires a holistic multi-pronged approach involving bushmeat awareness, protein and economic alternatives, law enforcement, and policy.
This link from the Bushmeat Crisis Task Force (BCTF) provides a great overview of what bushmeat is, . Director’s Note: The science and research done on the true impacts of animal agriculture is always growing. The statistics used in the film were based on the best information we had available while producing the film.
Relieving the bushmeat crisis will bring long-term benefits to wildlife and people and is a laudable goal for these reasons alone.
It will also help remove one more factor contributing to public confusion over hunting’s conservation value.

HIV/AIDS is a major public health concern and cause of death in many parts of Africa.
Although the continent is home to about percent of the world's population, more than two-thirds of the total infected worldwide – some 35 million people – were Africans, of whom 15 million have already died. Sub-Saharan Africa alone accounted for an . In order to bring a sub-regional focus on the bushmeat issue for West Africa and to produce effective solutions to this growing crisis, a conference was hosted in Ghana, and jointly organized by the FAO, WWF International, Ghana Wildlife.
