Could I ask you, First Minister, for your emerging thoughts on the work being taken forward by the Counsel General on rebuilding post COVD-19, and the similar work being developed by some of the big city mayors in England on the theme of 'building back better'? In this terrible ongoing tragedy of coronavirus, people have also seen, first-hand, the benefits of cleaner air, lower traffic, and more liveable streets and communities in places that were previously choked with pollution and congestion. And under lockdown, people have seen first-hand the quality-of-life benefits of vibrant, green spaces, as compared to tarmac and concrete, and more space and freedom to walk and cycle rather than to drive. So, First Minister, can I ask what measures can be put into place right now, and going forward as the restrictions may be eased, to enable more and more people to get around for work and recreation by walking and cycling, especially while the capacity of public transport remains constrained, so that we can avoid a calamitous return to traffic congestion, air and noise pollution and the associated health impacts, and so that we can respond to the very real underlying climate change emergency?
