I have got a question for all of you, do you know if fireworks are bad for the environment? Do you know if they cause pollution? People think their fun too watch and they are, but have you ever thought what they are doing to our planet all around the world? They are causing **__ AIR POLLUTION .__** It is ok to have them on special occasions like New Years Eve or Australia day but it is **__ NOT OK __** to have them every week or every day. P.S Please don't encourage people to do fireworks often.
