It petrifies me that 15,000 litres of water, 5 square meters of land and 30kg of greenhouse gas emissions are the cost of producing a mere kilo of beef.

With COP21 underway, I dearly hope that a meat tax is prioritised. Not only would such a tax reduce emissions, it could also benefit people's health and generate additional revenue that could be reinvested in more sustainable methods of producing food. To the naysayers who argue a meat tax would impact the poorest in society, I say the current path of inaction has infinitely greater costs.
