Correct Answer : Option (B) - Montreal Protocol – keeping us, our food and vaccines cool
Note : The theme for World Ozone Day 2021 is the “Montreal Protocol – Keeping us, our food, and vaccines cool”. The cold chain is very important in all countries and has a direct link in reducing food loss and food waste, protecting public health, and supporting the economy. The Montreal Protocol is closely linked to this sensitive sector and WOD is an excellent time to stand out in this often overlooked sector.
