One of the big changes to come out of the disruption this year was the fall in pollution levels as reported (among other media outlets) by the BBC last May: https://www.bbc.co.uk/news/av/uk-wales-52854219 . Organic farming and food production, a less wasteful way of life and the environment have been high on my interest lists for years. It has also been an extremely difficult and nerve-wracking year for the travel industry, but perhaps now’s the chance to bring about new, lasting eco-change strategies for the better and with it, a buoyant travel industry once more!
