Climate change was one of the hot topics of this year's virtual World Economic Forum. Luckily, one of the best options for cutting carbon emissions is relatively easy – planting trees.

There are some bold tree planting initiatives all round the world. China plans to plant 35 million hectares of trees in the north of the country by 2050, while banks and nations recently pledged more than $14 billion to accelerate a 'great green wall' across Africa.
But the reality is deforestation is happening at pace. Forests are called the lungs of the earth and scientists say we have to do more to keep them breathing, with scientists at Kew describing this decade as crucial for reforesting the earth.
