What would happen if flies went extinct?

Answered by Douglas Hiatt

If flies were to go extinct, our world would be dramatically different. Flies play a crucial role in the ecosystem, particularly in the process of decomposition. Without them, the decomposition of organic matter would slow down significantly, leading to a buildup of waste and potential health hazards.

One of the main functions of flies is to break down dead animals and organic waste. They are attracted to decaying matter, laying their eggs on it, and their larvae, known as maggots, feed on the decomposing material. This process not only helps to clean up the environment but also recycles nutrients back into the ecosystem.

Imagine a world without flies where dead animals, from small rodents to large mammals, would remain intact for longer periods. The carcasses would not be efficiently broken down, leading to an accumulation of rotting flesh and the spread of diseases. The smell would be overwhelming, and the overall aesthetic of our surroundings would be severely compromised.

Additionally, flies are essential pollinators for certain plant species. While bees are often credited as the primary pollinators, flies also play a significant role, especially for plants that have a foul odor or produce carrion-like flowers. These plants rely on flies to transfer pollen from one flower to another, ensuring their reproduction. Without flies, the diversity and survival of these plant species would be at risk.

Flies also contribute to the nutrient cycle by decomposing organic matter such as fallen leaves and logs. They break down these materials into smaller particles, facilitating the process of decomposition and nutrient release. This helps to enrich the soil and provide essential nutrients for other plants to grow and thrive.

In urban areas, flies are responsible for cleaning up after our pets. Dog waste left on the streets and parks would not be efficiently decomposed, leading to unsanitary conditions and the spread of diseases. Flies help to break down and recycle this waste, playing a vital role in maintaining cleanliness in our communities.

It’s important to note that not all species of flies are beneficial. Some, like the housefly, can be considered pests due to their attraction to human food and potential for spreading diseases. However, even these nuisance flies contribute to the decomposition process and nutrient cycling in their natural habitats.

The extinction of flies would have far-reaching consequences for our environment. The efficient decomposition of organic matter, the pollination of certain plant species, and the cleanliness of our surroundings would all be severely impacted. Flies, particularly blowflies, flesh flies, bush flies, and soldier flies, are essential composters that play a vital role in maintaining the balance and health of ecosystems.
