For pyrotechnics, which pollute the environment considerably, i.e. air, ground and sound pollution, I would propose a 10% tax on each of these. That is to say, an overall increase in the tax on pyrotechnics of 30%. Those who have enough money to buy pyrotechnics in these times will have no problem paying an extra 30%.
Because everyone can see the consequences of pyrotechnics the next day and someone has to pay for them, so why should we all pay for them if we do not all use them, so only those who use them should pay for them. A 30% increase in tax is, in my opinion, the minimum that can be used to successfully remedy the consequences after this.
