  • One very rare positive effect off the past few months has been on the environment.

  • Biggest ever reduction in the volume of carbon dioxide released into the world's atmosphere has been recorded since March.

  • At the height of the lock down, scientists discovered the daily emissions around the world dropped by more than 17%.

  • The biggest fall was in China, which saw a drop in emissions of 24%.
