"chicken ...population is now 21.4 billion – more than any other land vertebrate and an order of magnitude greater than any other bird. Over 60 billion are slaughtered every year – a rate of carcass accumulation that is unprecedented...” - https://www.newscientist.com/article/2187838-when-humans-are-wiped-from-earth-the-chicken-bones-will-remain/
”You are not mature enough to tell it like it is. Even that burden you leave to your children.”

"Both the emergence of geologically novel climates and the rapid reversion to Eocene-like climates may be outside the range of evolutionary adaptive capacity." https://www.pnas.org/content/early/2018/12/05/1809600115
Instead, the best road to an affordable carbon-free system follows a “broad path” that draws from a full portfolio of clean techs—wind, solar, storage but also “firm” low-carbon resources such as nuclear, carbon capture, & reliable but oft-neglected renewables such as geothermal. https://twitter.com/JesseJenkins/status/1072602388849156096

Bad #systemsthinking. If exponential growth of material flow continues at present rates we will hit another limit: "Global shipper Maersk says it will eliminate fossil fuels by 2050" https://qz.com/1486377/global-shipper-maersk-says-it-will-eliminate-fossil-fuels-by-2050/
In #SystemDynamics this is what we call a negative feedback loop: "Air pollution in India caused 1.2 million deaths last year" https://qz.com/1489086/air-pollution-in-india-caused-1-2-million-deaths-last-year/
System Dynamics models uncover these blind spots and can lead to better policies: "No such thing as sustainable palm oil – 'certified' can destroy even more wildlife, say scientists" https://www.independent.co.uk/news/world/asia/palm-oil-sustainable-certified-plantations-orangutans-indonesia-southeast-asia-greenwashing-purdue-a8674681.html

"Fisheries generate severe constraints for seabird populations on a worldwide scale, and those need to be addressed urgently. Indeed, seabirds are the most threatened bird group, with a 70% community-level population decline across 1950–2010"

It’s a sad reality: a troubling trend sees a 97% decline in monarch butterflies. “For every little thing that changes there’s not just one consequence – it’s a whole chain reaction.” https://www.theguardian.com/us-news/2018/dec/07/its-a-sad-reality-a-troubling-trend-sees-a-97-decline-in-monarch-butterflies?
