This is extremely worrying wildlife experts are warning. Quagga mussels have been described as 'ecosystem engineers' because their vast capacity to filter water upsets the natural balance throughout the food web. They eat some pollutants, but they turn it into concentrated toxic faeces which can poison drinking water for people and wildlife. - Halil

The Wildfowl & Wetland Trust’s head of conservation policy, Jeff Knott said: “This is a worrying, but entirely predictable, development that could be devastating to British wetlands. Quagga mussels are likely to indirectly cause suffering and death for hundreds of thousands of native animals, fish and plants and cost millions of pounds in tax and water bills to protect drinking water supplies. - Halil
