Planting trees saves the climate – or so many environmental organisations claim. Reforestation is being promoted all over the world. But how much does this help in the fight against climate change? It sounds tempting to think that if we plant enough trees, we won't have to change our lifestyle substantially to stop climate change. This theory is also backed up by science. In July 2019, a study by the Zurich Institute of Technology made headlines. It claimed that there are 900 million hectares of arable land available for reforestation worldwide and that two-thirds of man-made CO2 emissions could be offset in this way. But is it really that easy? Where can we find free land to plant new trees? And which reforestation method is the most effective? How can conflicts over land use be avoided? Who mediates between farmers and those who want to plant trees? How many billions of trees need to be planted to offset emissions? And do reforestation projects really have long-term benefits for our climate? This documentary seeks answers in Australia and India. #dwdocumentary #documentary #trees ـــــ DW Documentary brings you information beyond the headlines.
