Fireworks are one of the most classic ways to celebrate Independence Day each year during the Fourth of July. While this tradition provides Americans an opportunity to celebrate the founding of our nation with impressive displays of color across the night skies, it’s important that we are cognizant to the impacts they can have on our environment and wildlife. Especially as a sensitive barrier island community, we must acknowledge the risks that are inherent with our celebrations this summer.

How can fireworks be harmful?

The visual displays offered by fireworks are due to the chemical reaction during combustion, which releases many byproducts. Some of these byproducts can be harmful, such as carbon dioxide, carbon monoxide, and particulate matter amongst other into the air when fireworks explode. Though beautiful, the release of these substances negatively impacts air quality while further increasing the load of anthropogenic greenhouse gases Earth is taxed by.

Consumer and public firework shows can also cause potential harm to local wildlife such as shorebirds and sea turtles in the midst of their summer nesting seasons. Prolonged periods of loud, booming noises inherent in firework shows can disorient shorebirds and cause them to panic, or flush, potentially leaving their nests exposed. In these cases, chicks are more vulnerable to predators, heat impacts or off-leashed pets. Firework stress could potentially impact colony nesting shorebirds, such as the least terns and black skimmers currently nesting on the Sanibel Causeway, resulting in hundreds of birds being impacted.

Nesting sea turtles also have the potential to be severely impacted from fireworks on and around Sanibel and Captiva Islands. The bright, artificial light emitted can disorient nesting adults, leading to failed or abandoned nesting attempts. Newborn hatchlings are also at risk of becoming disturbed or disoriented from artificial light, potentially lowering hatchling survival rates.

Additionally, massive amounts of debris are left in coastal areas from firework displays, largely containing extremely small, plastic pieces that break apart from the firework upon detonation. These pieces are often almost imperceptible to the human eye but will remain in our coastal environments for hundreds of years. The microscopic size and slow breakdown time of these pieces make them a high risk for ingestion by countless species of local wildlife. Once ingested, plastic may cause severe harm or death to wildlife through internal blockages, contamination, buoyancy issues or other risk factors. Larger plastic debris also leads to entanglement, while both forms further contribute to microplastic pollution in global waters.

Current environmental conditions increasing threat

As the summer season begins, current conditions in Southwest Florida make the use of fireworks especially dangerous for the environment. Much of Florida has been experiencing an ongoing drought in 2025-2026 with Lee County currently facing moderate to severe drought conditions. Large portions of the U.S are also under extreme heat risk this 4th of July weekend, with heat index values in Southwest Florida expected to reach up to 109 degrees.

The combination of these factors put many regions of the state at heightened risk for wildfire outbreaks, especially when coinciding with the use of fireworks. The majority of wildfires are set unintentionally by humans and require 3 ingredients; an ignition source, dry vegetation and weather conditions. Fireworks act as an ignition source, quickly reaching high temperatures with the potential to spark nearby flammable objects. Ongoing drought conditions increase levels of dry, dead vegetation, acting as highly flammable ‘fuel’ sources for an ignited flame. Recent data suggests that heat waves increase wildfire risk due to an increased atmospheric demand for moisture and limited nighttime humidity, allowing fires to burn longer. The combination of these factors increases the risk for unintentional wildfires that can wreak havoc on humans, wildlife and our natural environment in Southwest Florida.

How to avoid these risks

While enjoying a fun-packed 4th of July weekend with loved ones, there are simple ways to protect yourself, wildlife and the ecosystems around you.

1.) Consult local regulations before purchasing or lighting any consumer fireworks. Certain consumer fireworks are legal on designated holidays in Florida, but local ordinances and active burn bans may override those allowances. Check updated city and county regulations and if a burn ban is active in your area before engaging with personal fireworks. If consumer fireworks are not allowed, consider attending a city or county approved public firework show to celebrate the holiday.

2.) In you do use consumer fireworks, avoid setting them off anywhere that wildlife may be present. Avoid coastal environments, protected wildlife areas or anywhere with signage posted declaring an area an active nesting or protected zone.

3.) Leave no trace! If you light off fireworks, collect all discarded pieces after use to avoid leaving any hazards in the environment. Look especially for small, plastic pieces that may have been discarded while remembering some pieces may be too small to be seen by the naked eye.

4.) Avoid setting off fireworks or combustible materials near any dry vegetation, brush or leaves. These materials are highly flammable and can contribute to an unintentional wildfire being sparked. Choose flat, noncombustible surfaces like concrete that avoid environmental impact to the extent possible.

5.) Leave it to the professionals. Many communities around Florida host large gatherings with firework shows that dwarf anything available to consumers. These shows have environmental protections in place, and fire safety professionals standing by. Enjoy the show with family and friends, and without the risks.

6.) Start new traditions! While fireworks are a part of wonderful memories for many, there are many more environmentally- sensitive practices we can engage in to celebrate the holiday such as laser/ drone light shows, smokeless firework alternatives or simply enjoying time with loved ones in nature.
