The billion tree plan - New forests for greater climate protection?

Planting trees will save the climate. At least, that’s the claim of many environmental organizations. As a result, massive reforestation efforts are taking place worldwide. But just how effective are these campaigns?

It sounds tempting: If we can just plant enough trees, we can halt climate change. And we won’t even need to change our lifestyles that much. It’s a theory promoted by science: A Swiss university study made headlines in July 2019 when it said that 900 million hectares of land are available for reforestation worldwide, and that reforesting this area would compensate for two thirds of CO2 emissions caused by human activity. But is it really that simple? How can conflicts over land use be avoided? Who will mediate between farmers and tree planters? How many billions of trees need to be planted to balance emissions? And are reforestation projects really of long-term use for our climate? This film reportage goes in search of answers in Australia and India.
