GR: The Earth could get along just fine without us. If anyone can think of an ecosystem function that requires our presence, I would like to hear about it. Circumstantial and fossil evidence indicates that even when human numbers were small, the fires, animal drives, and plant preferences had harmful effects. Ecosystem resilience absorbed early human impacts, but now with more than seven billion of us, the impacts are simply overwhelming earth ecosystems. Livestock? Earth could tolerate a few domestic beasts, but not the billions we have now. Watch the video.
The following By
“The movie goes far beyond the obvious impacts of livestock production such as overgrazing of rangelands, and talks about everything from water pollution (from manure) to energy use in the production of meat to the mistreatment of meat producing animals by humans. Overall it makes a very cogent and articulate argument against meat/dairy consumption.
“They even take on Alan Savory, advocate of more livestock production as a means of reducing global warming, pointing out that methane production from domestic animals is one of the largest contributors to warming climate, and vastly exceeds any ability of grazed grassland ecosystems to absorb more carbon.
“The video is full of facts illustrated with great graphs like how many more gallons of water or the amount of land required in the production of a hamburger vs. a veggie burger that will make it easy to understand why livestock are one of the greatest threats to global biodiversity and ecosystems” By
