Every year for various occasions we put off fireworks. Yes it's entertaining but is your entertainment really worth the pollution it causes. IT HARMS EVERYTHING! The Biosphere, Atmosphere, Hydrosphere, and Lithosphere. Just for a few minutes of entertainment we cause so much air polllution. Fireworks have many poisonous chemicals, that we inhale afterwards. That's why this Canada day I want our government to not do fireworks, but somthing even more entertaining and environmentally friendly. SO it's a win-win situation! :)
