People are using firework without consciousness in an extensive range of events from graduation parties to wedding ceremonies. However, I believe it should be abandoned so that its many negative aspects can be eliminated. First of all, it causes noise and light pollution which gives rise to damage on inhabitants of sky, in other word birds. Exposure to intensive light and sound makes birds disoriented and confused. Furthermore, all this chaos might result in injuries or even deaths. In fact, the victims of fireworks are not confined to birds. What the fireworks do is emit poisonous gases which are inhaled by many creatures including humans. These gases might bring about some biochemical reactions and result in diseases related to the respiratory system. In addition, heavy metals contained in fireworks can mix in water and soil. Contamination with heavy metals can pollute the environment where people breed livestock. To put it another way, even if one does not use firework, he or she may suffer from it indirectly. When all outcomes are taken into consideration, legislators will have prohibited the use of fireworks soon.
