The hon. Member for Strangford (Jim Shannon) has put his finger on the button, because this is about not flushing wet wipes, no matter what they are made from. Banning plastic in wet wipes is one step forward, but we need to do more. This is a UK-wide issue; no part of the UK is unaffected. What is the problem? Why am I talking about it so obsessively? First, microplastics from wet wipes pollute our rivers, lakes and oceans. They are ingested by marine animals, from plankton to whales, disrupting feeding, growth and reproduction. Microplastics cause internal injuries, digestive blockages and reduced nutrient absorption. They leach harmful chemicals such as bisphenol A, phthalates and flame retardants. They also absorb pollutants from sea water, such as heavy metals and persistent organic pollutants, which are then released into animals’ tissues upon ingestion. Those substances can cause hormonal disruption, immune suppression, developmental defects and death. Filter feeders, such as oysters and baleen whales—from very small to very big—are especially vulnerable. Microplastics can also alter sediment composition, affecting bottom-dwelling species, and they can destabilise entire marine ecosystems. They are very small, but they have a huge effect. Secondly, wet wipes block sewers and drive up water bills. They form fatbergs, trigger storm overflow spills, and cost a lot. In my water company area of Thames Water, it costs £40.7 million every year to clear the blockages. That is £200 million over the current five-year investment cycle.
