Todos vegetarianos

Parece ser que las vacas contribuyen más al cambio climático que los coches y los aviones. Así lo dice un informe de LEAD, un ente apoyado por el Banco Mundial, la UE, la FAO y varios Ministerios de Agricultura de países occidentales. Se puede descargar aquí, aunque es excesivamente largo.

The livestock sector is a major player, responsible for 18 percent of greenhouse gas emissions measured in CO2 equivalent. This is a higher share than transport. The livestock sector accounts for 9 percent of anthropogenic CO2 emissions. The largest share of this derives from land-use changes – especially deforestation – caused by expansion of pastures and arable land for feedcrops. Livestock are responsible for much larger shares of some gases with far higher potential to warm the atmosphere. The sector emits 37 percent of anthropogenic methane (with 23 times the global warming potential (GWP) of CO2) most of that from enteric fermentation by ruminants. It emits 65 percent of anthropogenic nitrous oxide (with 296 times the GWP of CO2), the great majority from manure. Livestock are also responsible for almost two-thirds (64 percent) of anthropogenic ammonia emissions, which contribute significantly to acid rain and acidification of ecosystems.

Es decir, que si queremos combatir el cambio climático tenemos que hacernos vegetarianos y dejar de comer carne y así reducir la población de vacas en el mundo.
