Oorsig/Review Each bite primes the carbon pump Through the perfection of evolution, each time a cow takes a bite of grass it triggers the plant to release exudates in order to receive in return the nutrients needed for rapid regrowth. The grass’s rate of photosynthesis goes up, more grass (biomass) is grown and more carbon is removed from the air and pushed down into the soil. The action of grazing repeatedly pushes the grass back into it’s growth stage and as long as grass is actively growing, not senescing, carbon is being removed from the atmosphere and sequestered into the ground. In a positive feed- back loop, this liquid carbon pathway supports a healthy underground ecosystem, building soil organic matter, creating humus and soils that are deep, well-functioning and fertile (3). When cows graze, the carbon cycle is boosted and each bite primes the carbon pump. Roaming, grazing cows sequester carbon Once you understand this process, it becomes clear that although the cow is breathing or belching as she grazes, for all the carbon she cycles through her metabolism, there is carbon also being removed from the air and sequestered into the soil. This means that, when she is exclusively fed her natural diet of grass, there is a net reduction in atmospheric carbon. Roaming, grazing cows sequester carbon. There is much debate, though limited scientific evidence, about the size of the vast herds of herbivores that roamed the grasslands of the world up to pre-industrial times (6). But one thing is for sure: the hu Ή‘Ι•‘́½˜΅₯±±₯½ΉΜ°½Θ‰₯±±₯½ΉΜ°½˜)Ρ‘•΄έ•Ι”Ή½Π…ΥΝ₯Ήœ…Ήδ±₯΅…Ρ₯ŒΑΙ½‰±•΅ΜΈ%Έ)™…Π°ΕΥ₯Ρ”Ρ‘”Ι•Ω•ΙΝ”Έ 䁝Ʌι₯Ήœ…ΉΝΡ₯΅Υ±…Ρ₯Ήœ)Ι…Α₯Α‘½Ρ½ΝεΉΡ‘•Ν₯Μ°Ρ‘•δ°…±½Ήœέ₯Ρ Ρ‘”)‘•Ι‰₯Ω½Ι½Ύ΅•…™…ΥΉ„‰•™½Ι”Ρ‘•΄°Α±…啐)„Α₯Ω½Ρ…°Ι½±”₯ΈΡ‘”Ι•‘ՍΡ₯½Έ½˜…Ρ΅½ΝΑ‘•Ι₯Œ)…Ι‰½ΈΡ‘…Ё‰Ι½Υ‘Ё <ȁ‘½έΈΡΌΑΙ”΅₯Ή‘ΥΝΡΙ₯…°)±•Ω•±Μ€ Θ€ΈΉέ‘•ΈΙ…镐…ΑΑΙ½ΑΙ₯…Ρ•±δ°…ΡΡ±”)έ₯±°½ΉΡ₯ΉΥ”ΡΌ‘ΌΡ‘₯ΜΈ) ½έ́ΑΙ½‘Ս”ΉΥΡΙ₯Ρ₯½Ύ™½½Α½έ•Ι•)‰δΡ‘”ΝΥΈ)Q‘”‰•…ΥΡ䁽˜έ½Ι­₯Ήœέ₯Ρ Ή…ΡΥΙ…°ΝεΝΡ•΅Μ₯Έ)Ρ‘₯́݅δ₯́ё…ЁΉ½Π½Ή±δ‘½•Μ„½ίŠéΙ…ι₯Ήœ)ΝΡ₯΅Υ±…Ρ”…ΉΝΑ••Υΐ…Ι‰½ΈΝ•ΕΥ•ΝΡΙ…Ρ₯½Έ₯Έ)Ρ‘”Ν½₯°°‰ΥЁ͑”…±ΝΌΑΙ½Ω₯‘•ΜΎέ₯Ρ „ΉΥΡΙ₯Ρ₯½ΥΜ)‰δ΅ΑΙ½‘ՍЁѼ‘•Θ‘•±Α™Υ°•ΉΩ₯Ι½Ή΅•ΉΡ…°Ν•ΙΩ₯•Μ)₯ΈΡ‘”™½Ι΄½˜΅•…Ё½Θ΅₯±¬ΈΉ…±°…‘₯•Ω•έ₯Ρ )ΉΌ₯ΉΑΥΡ́½Ρ‘•ΘΡ‘…ΈΡ‘”™Ι•”°Α•Ι•ΉΉ₯…°•Ή•Ιδ)Ν½Υɍ”½˜ΝΥΉ±₯‘ΠΈ(ΔΘ) ΥЁݔ…»ŠeЁх±¬…‰½ΥЁΙΥ΅₯Ή…ΉΡ́έ₯Ρ‘½ΥЁ„‰₯Π)΅½Ι”½Έ΅•Ρ‘…Ή”°ΝΌ±•ΣŠé½ΉΡ₯ΉΥ”Ρ‘”©½ΥΙΉ•δ)₯ΉΡΌ‘½ά…Ι‰½Έ΅½½½½Ω•ΟŠ˜Έ) …Ι‰½Έε±₯ΉœΡ‘ɽ՝ ΅•Ρ‘…Ή”)Ή½Ρ‘•ΘΉ…ΡΥΙ…°ε±”½ΥΊݑ•Έ…Ι‰½Έ₯Μ)ΥΝ•ΡΌΑΙ½‘Ս”΅•Ρ‘…Ή”₯ΈΡ‘”΅•Ρ…‰½±₯Ν΄)½˜΅₯Ι½‰•Μ­Ή½έΈ…́΅•Ρ‘…Ή½•ΉΜΈQ‘”΅…₯Έ)Ή…ΡΥΙ…°Ν½Υɍ•Μ½˜΅•Ρ‘…Ή”…Ι”έ•Ρ±…Ή‘́…Ή)™½Ι•ΝЁ™₯ɕ́…́ݕ±°…́ё”ΥΡ́½˜ΙΥ΅₯Ή…ΉΡ́…Ή)Ρ•Ι΅₯Ρ•ΜΈ%Ё₯́ё”Ν…΅”΅₯Ι½‰₯…°…Ρ₯½Έ…Ή)…ΝΝ½₯…Ρ•Ι•±•…Ν”½˜΅•Ρ‘…Ή”Ρ‘…Ё™₯Ή…±₯Ν•Μ)Α±…ΉΠ‘•½΅Α½Ν₯Ρ₯½Έ°‰”₯Ё½ΈΡ‘”Ι½ΥΉ₯ΈΡ‘”)Ι½ΡΡ₯Ήœ½˜ΥΉ•…Ρ•ΈΑ±…ΉΠ‰₯½΅…Ν́½Θ₯ΈΡ‘”ΥЁ½˜)…Έ…Ή₯΅…°Ρ‘…Ё₯́‘₯•ΝΡ₯ΉœΑ±…ΉΠ΅…ΡΡ•Θ°…±±•)•ΉΡ•Ι₯Œ™•Ι΅•ΉΡ…Ρ₯½ΈΈ)́‘₯͍ΥΝΝ•°έ‘…Ё₯́₯΅Α½ΙΡ…ΉΠ…‰½ΥЁ΅•Ρ‘…Ή”)‰•₯ΉœΑΙ½‘Ս•‰δ΅₯Ι½‰•Μ₯Έ„½ίŠéΙΥ΅•Έ)Ι…Ρ‘•ΘΡ‘…Έ™Ι½΄΅₯Ι½‰•Μ½ΈΡ‘”Ι½ΥΉ°₯́ё…Π)Ρ‘”½ά₯́…±ΝΌΑΙ½Ω₯‘₯ΉœΎέ₯Ρ ™½½‰δΡΥΙΉ₯Ήœ)Ι…ΝΜ°Ν½΅•Ρ‘₯Ήœέ”…»ŠeЁ•…Π°₯ΉΡΌΝ½΅•Ρ‘₯Ήœ)‘₯‘±δΉΥΡΙ₯Ρ₯½Ύё…Ёݔ…ΈΈ)́έ₯Ρ ½Ρ‘•ΘΉ…ΡΥΙ…°ε±•Μ°Ρ‘”΅½Ω•΅•ΉΠ½˜)…Ι‰½ΈΡ‘ɽ՝ ΅•Ρ‘…Ή”…Ή‰…¬ΡΌ <ȁ…Έ)Ρ…­”‘₯™™•Ι•ΉΠ±•ΉΡ‘́½˜Ρ₯΅”ΈQ‘”Ν‘½ΙЁɽΥΡ”)₯ΉΩ½±Ω•Μ΅•Ρ‘…Ή½ΡΙ½Α‘Μ°΅•Ρ‘…Ή”½α₯‘₯Ν₯Ήœ)‰…Ρ•Ι₯„°έ‘₯ ‘…Ω”‰••ΈΝ‘½έΈ₯ΈΝΡΥ‘₯•Μ)₯ΈΥΝΡΙ…±₯„€ ά€ΡΌ½α₯‘₯Ν”΅½Ι”΅•Ρ‘…Ή”Ρ‘…Έ)…ΡΡ±”ΑΙ½‘Ս”ΈQ‘”…Ρ₯½Έ½˜΅•Ρ‘…Ή½ΡΙ½Α‘́…±ΝΌ)…Ύ͕΅•Ρ‘…Ή”ΡΌ‘₯™™ΥΝ”™Ι½΄Ρ‘”…Ρ΅½ΝΑ‘•Ι”)₯ΉΡΌΝ½₯±ΜΡΌ‰”½α₯‘₯Ν•€ Π€ΈQ‘”Ν±₯‘ѱ䁱½Ή•Θ)Ι½ΥΡ”₯́ݑ•Έ΅•Ρ‘…Ή”₯ΈΡ‘”…Ρ΅½ΝΑ‘•Ι”₯Μ)½α₯‘₯Ν•‰δ‘ε‘Ι½α封Ʌ‘₯…±Μ‰…¬₯ΉΡΌέ…ѕȁ…Ή)…Ι‰½Έ‘₯½α₯‘”€ ΰ€°έ‘₯ …ΈΡ…­”ΥΐΡΌ€Δȁ啅ΙΜΈ)Q‘”‘ε‘Ι½α封Ʌ‘₯…°₯́Ή…ΡΥΙ—Šé΅…₯Έ΅•Ρ‘…Ή”)Ν₯Ή¬°½α₯‘₯Ν₯Ήœ€δΐ”½˜΅•Ρ‘…Ή”•΅₯ΝΝ₯½ΉΜΈ)%Ё₯́Ι₯Ρ₯…°ΡΌΥΉ‘•ΙΝΡ…ΉΡ‘…Ё΅•Ρ‘…Ή”°)ΑΙ½‘Ս•‰δ΅•Ρ‘…Ή½•ΉΜ•₯Ρ‘•Θ₯Έ‰½δΝ½₯±Μ)½ΘΡ‘”ΥΡ́½˜Ρ•Ι΅₯ѕ́½ΘΙΥ΅₯Ή…ΉΡ́…ΉΡ‘•Έ)½α₯‘₯Ν•‰…¬ΡΌ <ȁ•₯Ρ‘•Θ‰δ΅•Ρ‘…Ή½ΡΙ½Α‘Μ)½Θ‰δΡ‘”‘ε‘Ι½α封Ʌ‘₯…°°₯́Α…ΙЁ½˜Ρ‘”ε±₯Ήœ)…ΉΙ•ε±₯Ήœ½˜…Ι‰½ΈΈ9ΌΉ•ά…Ι‰½Έ₯́…‘‘•)ΡΌΡ‘”ΝεΝΡ•΄Έ]‘₯±”Ρ‘”ΉΥ΅‰•Θ½˜…ΡΡ±”½ΈΡ‘”)Α±…Ή•ΠΙ•΅…₯ΉΜ½ΉΝΡ…ΉΠ°Ρ‘•Ι”₯́ΉΌ₯ΉΙ•…Ν”₯Έ)…Ρ΅½ΝΑ‘•Ι₯Œ΅•Ρ‘…Ή”…́„Ι•ΝձЁ½˜Ρ‘•₯ȁ•ΉΡ•Ι₯Œ)™•Ι΅•ΉΡ…Ρ₯½Έ‰•…ΥΝ”Ή…ΡΥΙ—Šé΅•Ρ‘…Ή”Ν₯Ή­Μ)‰…±…Ή”ΑΙ½‘ՍΡ₯½ΈΈ)ΥΙΡ‘•Ι΅½Ι”°½έ́­•ΑЁ½ΈΑ…ΝΡΥΙ”½ΉΩ•ΙЁ₯ΉΡΌ)΅•Ρ‘…Ή”©ΥΝΠ€Δ”½˜Ρ‘”…Ι‰½ΈΡ…­•Έ₯Έ‰δΑ±…ΉΡΜ)‘ΥΙ₯ΉœΑ‘½Ρ½ΝεΉΡ‘•Ν₯Μ€ ΔΘ€ΈΉέ‘₯±ΝЁё₯́΅…δ)‘…Ω”„±½‰…°έ…Ι΅₯ΉœΑ½Ρ•ΉΡ₯…°€ΘԁΡ₯΅•ΜΙ•…Ρ•Θ)Ρ‘…Έ <Θ°₯Ё₯́ΝΡ₯±°½ΉΝ₯‘•Ι…‰±δ±•Ν́ё…ΈΡ‘”)…Ι‰½ΈΝ•ΕΥ•ΝΡΙ…Ρ₯½Έ‰•Ή•™₯Ρ́½˜έ•±°΅΅…Ή…•)Ι…ΝΝ±…Ή‘́ΑΙ•Ω₯½Υͱ䁹½Ρ•€ ΔΜ€
