`These super-fed crops are fed, highly efficiently, to farm animals, that we eat in turn. The scale of this operation is a large reason for the scale of the ongoing mass extinction of other organisms. The scientist Vaclav Smil, of the University of Manitoba, has calculated that simply measured by mass, humans now make up a third of land vertebrates, and the animals that we keep to eat – cows, pigs, sheep and so on – make up most of the other two thirds. All the wild animals – elephants, giraffes, tigers and so on – are now less than 5% by mass. It’s a measure of how they have been pushed to the fringes by humans. Humans change things in other ways – they now direct the evolution of the animals that are useful to them, by breeding and by genetic engineering: again, it’s a planetary novelty. ´ #biodiversity #biodiversityday #biodiversity2020 #biodiversityheritagelibrary #biodiversityexplained #biodiversityhotspot #biodiversityireland #biodiversityconservation #biodiversityofindonesia #indonesiabiodiversity #biodiversityloss #biodiversitylibrary #biodiversityph #protectbiodiversity #biodiversityindonesia #biodiversitypark #biodiversityofindia #biodiversitywarriors #biodiversitysociety #biodiversityweek #sgbiodiversity #marinebiodiversity #biodiversitygarden #biodiversityisawesome #biodiversitymatters #biodiversityfriend #biodiversityphotography #biodiversityeducation #extinctionrebellion #massextinction (hier: Isernhagen- Niederhägener Bauernschaft, Niedersachsen, Germany) https://www.instagram.com/p/B-wfuNWAnly/?igshid=vsmo0per42wj
