Methylmercury is one of the most dangerous pollutants on the planet, accumulating in ecosystems and the food chain, especially in the fish we eat. To combat this problem, scientists have developed genetically modified fish and flies capable of breaking down methylmercury and expelling it as a harmless gas.

This breakthrough represents a milestone in the fight against environmental pollution, as it could significantly reduce the amount of mercury present in water and food. If the technology is implemented on a large scale, it could transform how we address toxic pollution and protect human health and the planet's biodiversity.

Furthermore, this study sets a precedent in biotechnology applied to ecology, demonstrating that genetic modification can be a key tool for restoring polluted ecosystems. With further research, we could see organisms engineered to remove other types of pollutants in the future, thus improving water and air quality worldwide.
