environmental concern, definitely. large plastic and rubbish in general. it is a problem for platypus is because of the way they forage, they close their eyes in our use highly specialised bills to forage for food in the water. and so as a result of this kind of foraging behaviour, platypuses are prone to getting plastic and rubbish tangled around their necks. that could lead to definitely strangulation and death. more broadly, microplastics are also a big issue. we don t know exactly the impact to platypuses, but microplastics can definitely harm animals in a range of ways, including physical ingestion that could lead to malnutrition. and also, there s issues with toxicity that can impact reproduction, immune system, and generally metabolic problems and developing disorders. so, these microplastics can definitely pose impact to our freshwater environment, and there s still a lot to learn. that s all for now
