The interaction of human population, food production, and biodiversity protection

Research suggests that the scale of human population and current pace its growth contribute substantially to loss biological diversity. Although technological change unequal consumption inextricably mingle with demographic impacts on environment, needs all beings-especially for food-imply projected will undermine protection natural world. Numerous solutions have been proposed boost food production while protecting biodiversity, but alone these proposals are unlikely staunch biodiversity loss. An important approach sustaining well-being is through actions can slow eventually reverse growth: investing in universal access reproductive health services contraceptive technologies, advancing women's education, achieving gender equality.

Abstract Because of human action, the Earth has entered an era where profound changes in global environment are creating novel conditions that will be discernable far into future. One consequence may a large reduction Earth's biodiversity, potentially representing sixth mass extinction. With effective stewardship, change drivers threaten biota could alleviated, but this requires clear understanding drivers, their interactions, and how they impact ecological communities. This review identifies 10 anthropogenic discusses six (atmospheric CO 2 enrichment, climate change, land transformation, species exploitation, exotic invasions, eutrophication) biodiversity.

The paradoxical extinction of the most charismatic animals

PLoS Biology, Journal Year: 2018, Volume and Issue: 16(4), P. e2003997 - e2003997

Published: April 12, 2018

A widespread opinion is that conservation efforts disproportionately benefit charismatic species. However, this doesn't mean they are not threatened, and which species "charismatic" remains unclear. Here, we identify the 10 most animals show at high risk of imminent extinction in wild. We also find public ignores these animals' predicament suggest it could be due to observed biased perception their abundance, based more on profusion our culture than natural populations. hypothesize impairs because people unaware cherish face do perceive urgent need for conservation. By freely using image rare threatened product marketing, many companies may participate creating perception, with unintended detrimental effects efforts, should compensated by channeling part associated profits According hypothesis, would likely last as long massive cultural commercial presence accompanied adequate information campaigns about threats face.

The killing of a satellite-tagged male lion by trophy hunter in Zimbabwe July 2015 provoked an unprecedented media reaction. We analyse the global response to hunting lion, nicknamed "Cecil", study animal long-term project run Oxford University's Wildlife Conservation Research Unit (WildCRU). collaborated with media-monitoring company investigate development coverage spatially and temporally. Relevant articles were identified using Boolean search for terms Cecil AND 127 languages. Stories about Lion editorial increased from approximately 15 per day nearly 12,000 at its peak, mentions social reached 87,533 peak. found that, while there clear regional differences level saturation story, patterns this story remarkably similar across globe, that was no evidence lag between media.

The Critically Endangered western chimpanzee declines by 80%

American Journal of Primatology, Journal Year: 2017, Volume and Issue: 79(9)

Published: July 3, 2017

African large mammals are under extreme pressure from unsustainable hunting and habitat loss. Certain traits make particularly vulnerable. These include late age at first reproduction, long inter-birth intervals, low population density. Great apes a prime example of such vulnerability, exhibiting all these traits. Here we assess the rate change for western chimpanzee, Pan troglodytes verus, over 24-year period. As proxy in abundance, used transect nest count data 20 different sites archived IUCN SSC A.P.E.S. database, representing 25,000 estimated remaining 35,000 chimpanzees. For each sites, datasets 2 years were available. We site-specific global using Generalized Linear Models. At 12 detected significant negative trend. The subspecies as approximated by encounter rate, yielded 6% annual decline total 80.2% study period 1990 to 2014. This also resulted reduced geographic range 20% (657,600 vs. 524,100 km2 ). Poverty, civil conflict, disease pandemics, agriculture, extractive industries, infrastructure development, lack law enforcement, some many reasons magnitude threat. Our status update triggered uplisting chimpanzee "Critically Endangered" on Red List. In 2017, will start updating 2003 Action Plan chimpanzees provide consensus blueprint what is needed save this subspecies. plea greater commitment conservation West Africa across sectors.
