Covid Christmas: What are the Christmas Covid rules?

Pledge to protect those around us and our environment by wearing reusable face masks.
While masks are essential for stopping the spread of Covid-19, the issue of disposable masks could be disastrous for our environment.
According to Iberdrola, there are alternatives to the disposable mask, but most people in the world are using masks made of TNT, which are practical and cheap, but which are not designed to be washed.
A disposable mask is made of non woven fabric (TNT), which is non toxic, but takes 400 to 450 years to break down. Because of the global increase in use, health authorities and environmentalists are concerned about this new type of pollution. Land and ocean ecosystems could be threatened by this pollution if we do not tackle this issue now.
