In my opinion drinking fizzy drinks should be ban.
The most important reason is the amount of sugar that is put in it. For example in a can of soda there are 10 teaspoons of sugar, so imagine how many teaspoons of sugar their be in a 2 litre bottle! The last example is that those who drink this liquid a lot could get diabetes and could die.
In addition there is a drug in this drink called caffeine. For example this drug can lead to certain cancers, high blood pressure, irregular heart beat, and other problems.
Finally the water in these gas drinks are just simple tap water which could include chemicals such as chlorine.
In conclusion that is why drinking fizzy drinks should be ban.
