Pere Renom

“We have given you, O Adam, no visage proper to yourself, nor endowment properly your own, in order that whatever place, whatever form, whatever gifts you may, with premeditation, select, these same you may have and possess through your own judgement and decision […] We have made you a creature neither of heaven nor of earth, neither mortal nor immortal, in order that you may, as the free and proud shaper of your own being, fashion yourself in the form you may prefer.”
Oration on the Dignity of Man – Giovanni Pico della Mirandola

Cows and climate change

published on 26.09.2019

The cow is a ruminant animal and has 4 stomachs: the rumen, the reticulum, the omasum and the abomasum. The first two have a rich community of microorganisms that ferment the vegetation in anaerobic conditions, that is, without the presence of oxygen. Some of these microorganisms, the so-called archaea or archaebacteria release methane gas. This gas accumulates in the rumen and when there is too much pressure the cow expels it belching. A cow can emit about 250 liters of methane a day. Methane gas (CH4) rises to the atmosphere and interacts with infrared radiation and heats the atmosphere. It is a greenhouse gas 20-25 times more potent than CO2. Consequently, when we eat a beef steak somehow we are contributing to climate change. Ways are being studied to reduce methane emissions by means of anti-arch vaccines, by modifying the diet, or by selecting low-emission cow breeds. Instead of the dairy cow we will have the degassed cow.
