What are the most pressing drivers of extinction? And how can the principles of planetary health help address the sixth mass extinction? Wildlife is disappearing because of habitat degradation, overhunting, toxic pollution, deforestation, and climate change.
What’s causing the sixth mass extinction? Unlike previous extinction events caused by natural phenomena, the sixth mass extinction is driven by human activity, primarily (though not limited to) the unsustainable use of land , water and energy use, and climate change .
The Sixth Mass Extinction of Earth's biodiversity, distinct from previous such events because it is caused by human activities, has been acknowledged by many for at least 30 years.
17 lis 2013 · The scientific model of sixth mass extinction, showing that we are dramatically impoverishing the ecosystems (not only in macrofaunas but mostly in microfaunas), teaches us: (A) (an evidence) we are part of an instable system; (B) (an evolutionary insight) we would not be here without this instability; (C)
