The Article shows that Livestock sector is a major generator of Green house gases and that a global switch to diets that includes less meat and more fruits and veggies could reduce green house gas emissions.
A Chatham house report shows that the Livestock sector produces 7.1 Gigatons of CO2 equivalent a year. (15% of global green house gas emission.). This is equivalent to the greenhouse gas emission of the entire transport sector (cars, planes, ships etc combined.)
[ GHG emission of transport sector is 7 Gigatons per year. ]
United Nation’s Food and Agriculture (FAO) report shows that Demand for livestock products may grow by 70% by 2050.
A recent study published in the USA peer-reviewed journal Proceedings of the National Academy of Sciences (PNAS) shows that a global switch to a less-meat, more fruit and veggie diet could reduce food-related green house gas emissions by 2/3 and avoid climate damage of US $1.5 trillion.
