Here's a paragraph on the pollution caused by fireworks:

Fireworks, a staple of celebrations worldwide, have a darker side - they significantly contribute to environmental pollution. The colorful explosions in the sky release harmful chemicals, heavy metals, and particulate matter into the atmosphere, contaminating air, water, and soil. The combustion of fireworks emits pollutants like carbon monoxide, volatile organic compounds, and nitrogen dioxide, exacerbating respiratory issues like asthma. Additionally, the fallout from fireworks contains toxic substances like lead, mercury, and cadmium, which can seep into waterways and harm aquatic life. The noise pollution from fireworks also disrupts wildlife habitats and disturbs human populations. Furthermore, the residual ash and debris from fireworks can linger in the environment for weeks, posing long-term ecological risks. To mitigate these effects, many cities are opting for eco-friendly alternatives, such as laser light displays or community events focused on sustainability.
