Face masks should be mandatory during Covid-19 for many reasons.
Fundamentally, this virus spreads mainly be the mouth, like when someone sneezes. However, if something like that happens when the person is wearing a mask, Covid-19 will not be that easy to outspread.
Alternatively, masks can protect us in various ways. They are a simple barrier for your mouth when germs from other sources go onto your face. Also, masks can avoid you from toughing your face when you have dirty hands. Then, not only does it lessen your chance of getting the coronavirus, it also reduces the probability of getting other illnesses, such as the flu.
Furthermore, face masks act as a reminder that every time we see a face mask on the ground, we know that we are still in the pandemic crisis. If we keep fighting it, Covid-19 will eventually become defeatable.
There are also financial benefits. If you own a mask company, then people will buy your product and you will earn money. Then you will spend the money on other businesses, and the economy will run well.
In conclusion, face masks should be mandatory because they protect people, act as a reminder and boosts the economy.
