6. There is an ever-growing consensus within the scientific community that we have entered a sixth mass extinction (McDaniel & Borton, 2002; Thomas et al., 2004; Lewis, 2006; Steffen et al., 2007; Alroy, 2008; Jackson, 2008; Rohr et al., 2008; Wake & Vredenburg, 2008; Rockströöm et al., 2009; Zalasiewicz et al., 2010). The Sixth Extinction thus emphasises to the reader, quietly, that mass extinctions are truly global events. (2004) relegated it to sixth place in the mass extinctions league table , considering the biocrises to be a function of origination failure rather than elevated extinction rates. If this is junk science, surely plenty of scientists seem to like this kind of junk. A report on late Quaternary vertebrate fossil assemblages from the eastern San Francisco Bay region, California.

With the sixth mass extinction,1 climate change,2 and other major anthropogenic disturbances underway, understanding the wide range of vital benefits that societies derive from nature has become a global priority. Indeed, it is widely recognized that most Earth ecosystem processes are being altered by human activities, suggesting that we may have entered a human-dominated geological epoch called the “Anthropocene” , and that humans are causing the sixth mass species extinction (e.g., [13,14]).

Avoiding a true sixth mass extinction will require rapid, greatly intensified efforts to conserve already threatened species and to alleviate pressures on their populations—notably habitat loss, overexploitation for economic gain, and climate change (31–33). Fossils and phylogenies: learning from our past. Extinction is not a moment or singular event. Mass extinction episodes detected in the fossil record have been measured in terms of rates of global extinctions of species or higher taxa (e.g., ref.

Biologists predict that unless we change course and begin preserving more species, within the next few hundred years, we will become the cause of Earth's sixth mass extinction. Although scientists also agree that Earth is now suffering the sixth mass extinction, they disagree about its consequences. Mass extinctions are defined as the loss of the majority of species in a relatively short geological time, caused by a catastrophic natural event (2).

The flora of the island of St Helena provides an amplified system for the study of extinction by reason of the island’s high endemism, small size, vulnerable biota, length of time of severe disturbance (since 1502), and severity of threats. 2014). The case for sea-level change as a dominant causal factor in mass extinction of marine invertebrates. However, it is not generally considered as a primary factor in causing the actual endangerment or extinction of species. The Earth appears to be at the beginning of sixth massive species extinction. 1997. This extinction of a larger number of animals together is called as the mass extinction. As the new species start to evolve, the older species tend to get depleted from the surface of the earth.

Crossing boundaries between bioacoustics, acoustic ecology, electroacoustic technology and music composition, the project aims to reveal the ordered structures of nature's sonic habitats, define a possible model of compositional integration and make the outcome accessible to audiences to foster awareness on the current “sixth mass extinction.” They were caused by major geologic and climatic events. The effects of these and other drivers such as habitat fragmentation, pollution, pathogens, the introduction of nonnative species, and, notably, global climate change provide mounting evidence that humans are poised to cause a sixth mass extinction event (Barnosky et al., 2011).
