Mass extinctions March 2nd

“Although extinction is a natural phenomenon, it occurs at a natural “background” rate of about one to five species per year. Scientists estimate we’re now losing species at 1,000 to 10,000 times the background rate, with literally dozens going extinct every day. It could be a scary future indeed, with as many as 30 to 50 percent of all species possibly heading toward extinction by mid-century…. Unlike past mass extinctions, caused by events like asteroid strikes, volcanic eruptions, and natural climate shifts, the current crisis is almost entirely caused by us — humans. In fact, 99 percent of currently threatened species are at risk from human activities, primarily those driving habitat loss, introduction of exotic species, and global warming ”   http://www.biologicaldiversity.org/programs/biodiversity/elements_of_biodiversity/extinction_crisis/

 

Although we are causing extinctions to occur over a thousand times more than normal, technology is also helping us in conservation efforts. http://news.nationalgeographic.com/news/2014/05/140529-conservation-science-animals-species-endangered-extinction/

 

“The Holocene extinction, otherwise referred to as the Sixth extinction or Anthropocene extinction, is the ongoing extinction event of species during the present Holocene epoch mainly due to human activity.” https://en.wikipedia.org/wiki/Holocene_extinction

 

Almost a quarter of the world’s mammals are facing extinction within thirty years. Here is a link to hundreds of articles about the mass extinction that is going on. Please feel free to explore them. http://www.mysterium.com/extinction.html
