"many peer-reviewed studies, ... put livestock emissions at between 14.5 percent and 19.6 percent of the world’s total"

"... it doesn’t factor in the significant climate benefits we’d get if we freed up some of the land now dedicated to livestock farming and allowed forests to return, unlocking their potential as “carbon sinks” that absorb and sequester greenhouse gases from the air.

Scientists call this the opportunity cost of animal agriculture’s land use. Because animal farming takes up so much land — nearly 40 percent of the planet’s habitable land area — that opportunity cost is massive ...

"One study found that ending meat and dairy production could cancel out emissions from all other industries combined over the next 30 to 50 years."

> we can save the environment and continue to enjoy products we consider to be important to our lifestyles
