All about 6th Mass Extinction.

All about 6th Mass Extinction Sixth mass extinction • The Holocene extinction, otherwise referred to as the sixth mass extinction or Anthropocene extinction, is an ongoing extinction event of species during the present Holocene or Anthropocene epoch, as a result of human activity. Source: Google Images Massive extinction • The included extinctions span numerous families of plants and animals, including mammals, birds, amphibians, reptiles and arthropods, with widespread degradation of highly biodiverse habitats such as coral reefs and rainforests. Source: Google Images Currently under way • A “biological annihilation” of wildlife in recent decades means a sixth mass extinction in Earth’s history is under way and is more severe than previously feared, according to research. Scientists analysed both common and rare species and found billions of regional or local populations have been lost Source: Google Images Who is to be blamed? • They blame human overpopulation and overconsumption for the crisis and warn that it threatens the survival of human civilization, with just a short window of time in which to act. It is a frightening assault on the foundations of human civilization Source: Google Images Millions of species lost • The scientists found that a third of the thousands of species losing populations are not currently considered endangered and that up to 50% of all individual animals have been lost in recent decades. Source: Google Images Extinction progress way beyond • The scientists found billions of populations of mammals, birds, reptiles and amphibians have been lost all over the planet, leading them to say a sixth mass extinction has already progressed further than was thought. Source: Google Images Humans are responsible • Wildlife is dying out due to habitat destruction, overhunting, toxic pollution, invasion by alien species and climate change. But the ultimate cause of all of these factors is human overpopulation and continued population growth Source: Google Images Overconsumption • Overconsumption, especially by the rich, is one of the main causes. The serious warning needs to be heeded because civilisation depends utterly on the plants, animals and organisms of Earth that supply it with essential ecosystem services Source: Google Images What can be done? • The time to act is very short. It will, sadly, take a long time to humanely begin the population shrinkage required if civilisation is to long survive, but much could be done on the consumption front and with wildlife reserves, diversity protection laws, in the meantime.
