Earthworms like to eat some plastics, but side effects of their digestion are unclear

Plastic pollution is a major environmental issue that has been affecting the planet for decades. Plastic waste has been found in every corner of the world, from the deepest parts of the ocean to the highest peaks of mountains. Scientists have been working hard to find ways to reduce plastic pollution, and one solution that has been proposed is using earthworms to break down plastic waste. Recent studies have shown that earthworms can eat some types of plastics, but the side effects of their digestion are still unclear.

What are earthworms?

Earthworms are invertebrates that belong to the phylum Annelida. They are commonly found in soil and play an important role in maintaining soil health. Earthworms help to break down organic matter in soil, which releases nutrients that plants need to grow. They also help to aerate soil by burrowing through it, which improves water infiltration and drainage.

Plastic pollution

Plastic pollution is a major environmental issue that has been affecting the planet for decades. Plastic waste takes hundreds of years to decompose, and it can harm wildlife and ecosystems. Plastic waste can also enter the food chain, which can have negative impacts on human health.

Earthworms and plastic

Recent studies have shown that some types of earthworms can eat certain types of plastics. In a study published in Environmental Science & Technology, researchers found that two species of earthworms were able to consume polyethylene, which is one of the most common types of plastic used in packaging.

The researchers found that the earthworms were able to break down the polyethylene into smaller pieces, which they excreted as fecal matter. The fecal matter contained microplastics, which were smaller than 5mm in size.

Side effects of earthworm digestion

While it is promising that earthworms can eat some types of plastics, the side effects of their digestion are still unclear. The researchers found that the fecal matter produced by the earthworms contained microplastics, which could potentially enter the food chain.

The researchers also noted that the earthworms' digestive systems could be affected by the plastics they consume. The plastics could potentially cause blockages in the earthworms' digestive tracts, which could lead to health problems.

Conclusion

Earthworms have shown promise in breaking down plastic waste, but more research is needed to fully understand the side effects of their digestion. While it is important to find solutions to plastic pollution, it is also important to consider the potential impacts of those solutions on ecosystems and wildlife.
