Key to Brazil’s deforestation may be in its cows, pastures

At an experimental government farm in the western Amazon’s Rondonia state, researchers analyze grass seeds under microscopes, shake soil samples in test tubes, and measure the milk production of a new breed of cows.

While high-profile police raids targeting illegal ranchers and loggers in the Amazon grab more headlines, these scientists may produce a more important solution in the long fight to save the greatest rainforest.
