LIFE OUT OF BALANCE
From this chart we see that in 10,000 BCE (12,000 years ago) wild animals comprised 100% of the total vertebrate biomass on this planet. Today, wild animals comprise only 4% — less biomass than the cats and dogs that we humans keep for pets. The world’s cattle now comprise a greater biomass than all other animal species combined. Now you can believe that methane from cattle can make a deadly difference.
