  Figure: Greenhouse gas emissiplbvo5w 4u9 in.q, r,rons across the food supply chain


Greenhouse gases are emitted all along the food supply chain. It starts with deforestation to change land for agriculture. On the farm, fossil fuels are burned to run machinery, and both animals and plants may release greenhouse gases. A small portion of the total greenhouse gases is released after this in processing, transporting, packaging and selling the food.

With reference to the Figure, estimate what fraction of beef’s greenhouse gas emissions are likely to be from methane, manure (animal urine ad faeces) and farm machinery.

Brazil and Luxembourg had high $CO_2$ emissions between 2010 and 2014.
III.
France and Spain had the same amount of $CO_2$ emissions due to deforestation for food production during that time.
