A critical evaluation of the region’s biodiversity and ecosystem services. It evaluates the contributions of biodiversity and ecosystem services as well as identifying major trends in these. Focus is given to different subregions, their distinct biomes, cultures and socio-economic differences. The region is highly biodiverse, with 20% of globally identified key biodiversity areas, some of the planet’s most extensive wilderness, and the largest barrier reef in the Western hemisphere. It is also the main origin of multiple important crops. However, the region faces many environmental issues: climate change, land and habitat degradation, pollution, economic disparity, land ownership rights, growing urbanisation, natural resource exploitation, and mistreatment of indigenous and local peoples.
