One of Brazil’s protected trees. Since 2000 Brazil has established the world’s largest network of protected areas to conserve the environment, spanning at least 1.5m sq km. Brazil has seen an 80% reduction of deforestation in the Amazon in the last decade, but in recent years there has been a worrying upturn in deforestation. So in December 2016, the government pledged the ‘largest restoration commitment made by any nation’ to re-establish by 2030 12m hectares of forest land that has been degraded or deforested.
