Small, fast [ i.e., short-lived ], insect-eating animals to predominate in the future: Study
Animals such as tawny eagle and black rhinoceros that are slow-lived [ i.e., long-lived ] and require special environmental conditions are likely to face extinction over the next 100 years

Slow-lived [ i.e., long-lived ] species likely to become extinct; world will shift to smaller animals over next century: Study
Smaller birds and mammals, which can thrive in a wide variety of habitats, are more likely to avoid becoming extinct over the next 100 years, scientists say.

Abstract [ open access ]
Species, and their ecological strategies, are disappearing. Here we use species traits to quantify the current and projected future ecological strategy diversity for 15,484 land mammals and birds. We reveal an ecological strategy surface, structured by life-history (fast–slow) and body mass (small–large) as one major axis, and diet (invertivore–herbivore) and habitat breadth (generalist–specialist) as the other. We also find that of all possible trait combinations, only 9% are currently realized. Based on species’ extinction probabilities, we predict this limited set of viable strategies will shrink further over the next 100 years, shifting the mammal and bird species pool towards small, fast-lived [ i.e., short-lived ], highly fecund, insect-eating generalists.
"Controlled capitalism … had been a truly colossal success. From the end of the Second World War until the mid-1970s the American and European economies were uplifted by many years of rapid growth, bringing affluence from the relatively few to almost all."
"In the late 1970s the tendency to control capitalism was abruptly reversed."
“ … the most striking feature of our turbo-capitalist times, the hollowing-out of democratic governance over the economy.”
