Global raptor research and conservation priorities: Tropical raptors fall prey to knowledge gaps (2019, background): “The cur‐ rent rate of species extinctions is estimated to be as much as 1,000 times greater than pre‐human levels, approaching levels that merit recognition as Earth's sixth mass extinction event (Barnosky et al., 2011).”
Overfishing drives over one-third of all sharks and rays toward a global extinction crisis. (2021, neutral): “increased extinctions, with some postulating life on earth is facing its sixthmass extinction.(5) In the ocean, the extinction risk has increased most recently over the past century with the growth of human populations and associated intensification of industrial fishing and technological efficiency”
Ecological intensification of agriculture — sustainable by nature (2014, background): “Yet one thing is known for certain: the current model of agricultural intensification is not sustainable (socially and thermodynamically), it is neither ecological nor eco-efficient, it is ineffective at feeding the world, it is harmful for the environment and contributes to biodiversity loss [15–21”
Impacts of climate change on the future of biodiversity (2012, background): “Nevertheless, even these global estimates suggest major losses of biodiversity due to global climate change that are generally higher than current rates of loss and far higher than rates of species extinctions documented in the fossil record (Pereira et al. 2010; Barnosky et al. 2011).”
Historic and prehistoric human‐driven extinctions have reshaped global mammal diversity patterns (2015, background): “, 2011), massive environmental changes (IPCC, 2013) and a looming planetary biosphere state shift (Barnosky et al., 2011).”
Beyond species loss: The extinction of ecological interactions in a changing world (2015, background): “Current estimates of species extinctions are three to four orders of magnitude above background extinction rates (Barnosky et al. 2011).”
Biodiversity in a changing climate: a synthesis of current and projected trends in the US (2013, background): “In many cases, these other stressors have been, or are currently, the primary drivers of biodiversity loss (Master et al. 2009) and will interact with climate change to affect the vulnerability of species and populations (Barnosky et al. 2011; Mantyka-Pringle et al. 2011).”
