In March 2016, the United Nations held its first annual International Day of Forests, a worldwide celebration and recognition of the important of forests in the world’s eco system. One third of the Earth’s land mass is covered by forests, with an estimated 1.6 billion people depending on forests for their income. Despite the importance of forests, the speed of deforestation does not seem to be slowing, and experts estimated that as much as 20% of greenhouse gases are emitted as a consequence. Surely therefore saving existing forests and planting new ones is something we should all be on board with? There are many projects, small and large, to halt or reverse the trend for cutting trees down, and some surprising criticisms.
