28 Jul 2016 --- A new study, published in the journal PLOS ONE, found high levels of oil palm-driven deforestation over a 25-year period in Southeast Asia and South America, but relatively low levels in Mesoamerica (Mexico, Central America and the Caribbean) and Africa. Three of the countries studied – Ecuador, Peru and Indonesia – had the greatest levels of observed deforestation within sampled sites, with more than half of the oil palm grown on land deforested during the study period.
