This is an existential crisis and animal agriculture is at fault. Here is the science to prove it:

THE SCIENCE

Biological annihilation via the ongoing sixth mass extinction signaled by vertebrate population losses and declines – Proceedings of the National Academy of Sciences (PNAS)

“The population extinction pulse we describe here shows, from a quantitative viewpoint, that Earth’s sixth mass extinction is more severe than perceived when looking exclusively at species extinctions. Therefore, humanity needs to address anthropogenic population extirpation and decimation immediately…

Earth is experiencing a huge episode of population declines and extirpations, which will have negative cascading consequences on ecosystem functioning and services vital to sustaining civilization. We describe this as a “biological annihilation” to highlight the current magnitude of Earth’s ongoing sixth major extinction event….

conservatively almost 200 species of vertebrates have gone extinct in the last 100 y. These represent the loss of about 2 species per year. Few realize, however, that if subjected to the estimated “background” or “normal” extinction rate prevailing in the last 2 million years, the 200 vertebrate species losses would have taken not a century, but up to 10,000 y to disappear, depending on the animal group analyzed.”

“Ecosystems, species, wild populations, local varieties and breeds of domesticated plants and animals are shrinking, deteriorating or vanishing. The essential, interconnected web of life on Earth is getting smaller and increasingly frayed,” said Prof. Settele. “This loss is a direct result of human activity and constitutes a direct threat to human well-being in all regions of the world.”

I.P.C.C. Special Report on Climate Change and Land – 2019 – Intergovernmental Panel on Climate Change (IPCC)

“ …population growth and changes in (food) consumption patterns have caused unprecedented rates of land and water use…Some dietary choices require more land and water, and cause more emissions of heat-trapping gases than others,” said Debra Roberts, Co-Chair of IPCC Working Group II…

Balanced diets  featuring plant-based foods, such as coarse grains, legumes, fruits and vegetables, and animal-sourced food produced sustainably in low greenhouse gas emission systems, present major opportunities for adaptation to and limiting climate change,” she said.

U.S Academics Feel the Invisible Hand of Politicians and Big Agriculture

“ Agri-business has funded research which has advanced its interests and suppressed research which undermines its unfettered growth… compromised academic integrity by way of industry related golden handcuffs”

Global Farm Animal Production and Global Warming: Impacting and Mitigating Climate Change

“The farm animal sector is the single largest anthropogenic user of land, contributing to many environmental problems, including global warming and climate change.”

Causes of Deforestation of the Brazilian Amazon

“The fact that cattle ranching is viable from the private perspective does not mean that the activity is socially desirable or environmentally sustainable. Private gain needs to be contrasted with the environmental (social) costs associated with cattle ranching and deforestation.”

Analysis and valuation of the health and climate change co-benefits of dietary change

“Transitioning toward more plant-based diets that are in line with standard dietary guidelines could reduce global mortality by 6–10% and food-related greenhouse gas emissions by 29–70% compared with a reference scenario in 2050…

The food system is responsible for more than a quarter of all greenhouse gas emissions while unhealthy diets and high body weight are among the greatest contributors to premature mortality.”

Livestock – Climate Change’s Forgotten Sector: Global Public Opinion on Meat and Dairy Consumption

“Consumers with a higher level of awareness were more likely to indicate willingness to reduce their meat and dairy consumption for climate objectives. Closing the awareness gap is therefore likely to be an important precondition for behaviour change.”

The Sustainability Challenges of Our Meat and Dairy Diets

“Continuing high consumption of livestock products in nearly all developed countries, and increasing demand for livestock-based foods in large transition economies, are creating serious problems of prolonged and persistent environmental and social degradation. These problems are further exacerbated and affected by climate change and risks, biodiversity loss, water stress, and water pollution.”
