Quite often recognized actions aimed at replanting trees are not always productive. The researchers therefore believe that future efforts will be needed to select species adapted to the environment in the context of increasingly alarming global warming. In 2020, a researcher from the Department of Environmental Studies at the University of California, Santa Cruz (United States) argued that planting trees to protect the environment is sometimes a counterproductive strategy. This especially applies to poorly thought-out or poorly prepared reforestation projects, which can cause more negative than positive effects. In addition, taking measures to regulate land clearing would be more useful for the preservation of forests and their biodiversity. (Demeure, geographer, more at sciencepost.fr)
