And factory farming risks more than local communities. Cattle ranching is the primary cause for the
deforestation of Brazil’s rainforests, which is an issue not only because of the forests’ role in offsetting carbon
emissions, but also because it causes a significant loss of biodiversity. For this reason, among others,
Guardian columnist George Monbiot writes in his new book,
Regenesis: Feeding The World Without Devouring The Planet, “land use should be seen as perhaps the most important of all environmental issues.” Studies have shown that species are going extinct
1,000 times faster than in pre-human times. If deforestation in the Amazon continues, the rainforest could reach a
tipping point at which its entire ecosystem could collapse. Scientists say that there’s already a
mass extinction event underway, and that the “window of opportunity” to counteract it is “rapidly closing.”
