Rainforests provide a public good. The world should pay to conserve them

At last, good news from the Brazilian Amazon. In the first eight months of 2023, the pace of deforestation has fallen by nearly 50% compared with last year. This reflects a change of government. Jair Bolsonaro, Brazil’s president from 2019 to 2022, was an outspoken chum of the loggers and ranchers who are slicing down and burning the rainforest. Not only did he make no effort to stop them; he went out of his way to hobble the agencies charged with policing environmental crimes.

His ejection by voters last year gave the Amazon a much-needed respite. His successor, Luiz Inácio Lula da Silva, actually cares about conservation. As we report this week, gun-toting federal agents are once again making a serious effort to shut down illegal mining operations and blow up their equipment.
