Unformatted text preview: Bioengineered Meat Kia s. and Mani H. Is this a good or bad thing for the future? Kia S. Positive Environmental Impact: There are 1.5 billion animals that are used for meat alive in the world right now, and they use up a lot of resources and create a lot of wastes. In Vitro meat will reduce greenhouse gas emissions of the meat industry by 80% (penn,2009). It takes 10 liters of gas to produce 1 pound of beef! 80% of deforestation of the Amazon forest is to make room for livestock farms and feeding ground. This further adds to the problem since the trees in the Amazon are needed to consume CO 2 from the atmosphere. The areas of the world that are CO2 reducers are being turned into CO2 producers (Hyena, 2009) Farm animals, specially cows produce a lot of greenhouse gasses in their digestive systems, and most people dont realize how big of a problem they are. Livestock create: 68% of the ammonia that goes into the atmosphere. Ammonia in the atmosphere causes acid rain that kills fiish and destroys forests. 65% of nitrous oxide which is one of the worst greenhouse gasses (it traps 310X more heat in the atmosphere than carbon dioxide). 37% of methane emissions (traps 21X more gas than CO2 ) 9% of the carbon dioxide emissions The worlds carbon dioxide emissions are currently at 440 billion tonnes a year. If currently livestock are responsible for 9% of CO2 emissions, that means livestock are currently pumping out 40 billion tonnes of carbon dioxide. Wwitching from conventional farming to in vitro meat will reduce greenhouse gas emissions by 80%. If 80% of CO2 emissions were reduced by switching cultured meat markets, the CO2 emissions from the meat industry would approximately become 3 billion tonnes a year. This is a reduction in 32 billion tonnes of reduction for CO2 alone, and carbon dioxide is the least dominant gas that is emitted by livestock (just 9% of worldwide emissions) (Hyena, 2009). It is estimated that 51% of the worlds greenhouse gas emissions are caused by the 1.5 billion animals in the worlds livestock. Moving meat production to labs will reduce the worldwide gas emissions by more than 40%. This is a huge reduction and could slow down global warming substantially (Hyena, 2009). Efficient production and low cost: 500 billion pounds of meat is consumed every year in the world, this number is expected to double by 2050 (Hyena, 2009). It takes a lot of resources to produce meat, animals have to be fed and hydrated for a long time before they are slaughtered for their meat. It takes 7500 liters of water to produce just one kilogram of beef. That is the amount of water an average Canadian would drink in 10 years. 8% of the worlds drinkable water supply goes to farm animals. Since a whole animal doesnt need to be of the worlds drinkable water supply goes to farm animals....
