1. 18% of greenhouse gas emissions come from livestock.
With rising production of beef and therefore rising numbers of livestock on the planet, this percentage is predicted to increase drastically over the next decade.
2. The crop fertilizers used to feed the livestock are equally hazardous
The fertilizers (which are developed from fossil fuels) that are used in producing feed for livestock emit 41,000,000 tonnes of CO2 a year. At the same time, on-farm fossil fuels may contribute an added 90,000,000 tonnes of CO2 a year.
3. The land cleared to make way for new livestock is environmentally dangerous
To continue, the land which is cleared to make new room for the ever expanding "global-farm" is resulting in the added production of 2,400,000 tonnes of CO2 annually.
4. Farm animals fart, shit, and burp methane
An estimated 2,200,000 tonnes of methane (stronger and worse than CO2) is released by these delicious critters annually.
5. Nitrogen Oxide adds CO2 too
The nitrogen fertilizers used on land produce dangerous greenhouse gases that produce 2,200,000 tonnes of CO2 annually.
