We examine the extent to which planting trees could help to mitigate climate change. Professor Tom Crowther of ETH Zurich University tells us how many trees could have a meaningful impact on global carbon dioxide levels. Darren Woodcroft of the Woodland Trust explains his organisation's plans for planting trees in the UK. We hear from Malian singer Inna Modja, about her documentary The Great Green Wall which reflects the ambition to reforest an 8,000km belt across the degraded landscapes of the Sahel. And we ask Dr Susan Cook, forest restoration scientist at The Nature Conservancy in the United States, whether her organisation's aim to plant a billion trees is feasible. Also in the programme, we gauge market reaction to Iran's bombing of two bases used by US troops in Iraq, and ask David Braithwaite, professor of safety and accident investigations at Cranfield University in the UK, what might have caused a Ukraine International Airlines flight from Tehran to Kyiv to crash. Plus as Nissan chief executive turned international fugitive Carlos Ghosn gives his first press conference in Beirut, Lebanon, the 大象传媒's business editor Simon Jack brings us the details.
