How big beef and soya firms can stop deforestation

THE WORLD’S emissions of carbon dioxide may fall by 7% this year because of lockdowns in response to the pandemic, according to Nature Climate Change, a journal. Brazil is a glaring exception. Its emissions will rise by 10-20% from 2018, when they were last measured, says the Climate Observatory, a consortium of research outfits. The culprit is deforestation. In the first four months of 2020 an estimated 1,202 square km (464 square miles) were cleared in the Brazilian Amazon, 55% more than during the same period in 2019, which was the worst year in a decade. Come August, when ranchers set fire to cleared areas to prepare them for grazing, runaway blazes could outnumber those that shocked the world last year. Scientists say tree loss is nearing a “tipping point”, after which trees will dry out and die, releasing billions of tonnes of carbon into the atmosphere.
