"We are living through a geological era that scientists have termed the Anthropocene, an age in which human activity is recognized as the most dominant and destructive influence on Earthβs climate, environment, and ecosystems. Among these activities, human use and abuse of animals is implicated in multiple overlapping crises, from climate change to many of the worst pandemics in history, as well as unprecedented rates of biodiversity loss and species extinction.
Between 1970 and 2018, global wildlife populations fell by nearly 70%, while species in freshwater lakes, rivers and wetlands declined by an average of 83%. Species are going extinct 1,000 times faster than in pre-human times, at a rate that far exceeds the worst extinction event in history.
Apace with these staggering rates of wildlife disappearance, numbers of domesticated animalsβmostly farmedβhave soared to a stupefying artificial imbalance. A report published in the Proceedings of the National Academy of Sciences found that farmed poultry now comprise 70% of all bird biomass on the planet, while 60% of all mammalian biomass belongs to animals who are farmed (mostly cattle and pigs); 36% is human; and a mere 4% is wild. Across the globe, wild creatures and their homes continue to be displaced on a massive scale to make room for ever more grazing pasture and vast feed crop monocultures for farmed animals.
Itβs no coincidence that our systematic destruction of animal lives is also destroying the planet. Increasingly, we are seeing an alarming feedback loop between human health and ecological crises, whereby the intensification of one exacerbates and increases one or more of the others.
To return to a previous example, farming animals is a major driver of climate change. Climate change is a leading cause of global food insecurity. The production of animal-based foods, with such disproportionate land requirements, is also the single greatest driver of deforestation and habitat loss. Deforestation, in turn, is a leading cause of climate change, biodiversity loss, species extinction, and zoonotic diseases and pandemics.
In light of these converging catastrophes, epidemiologists, environmental scientists, food security and global health experts, including the World Health Organization, have instituted a 'One Health' framework that emphasizes the interdependence of human and nonhuman animal well-being and the health of ecosystems."
