Afternoon, Minister. As the Senedd champion of the freshwater pearl mussel—I know other Members are champions of their own different species as well—I'm particularly interested in this question from Caroline Jones, and in the convention strategic plan for diversity, which ran from 2011 until last year. Species like the freshwater pearl mussel are particularly susceptible to water pollution, and their continued presence in the River Wye in my constituency is dependent upon the pollution being kept to a minimum. Has the Welsh Government examined the impact of the convention's work, particularly in relation to water standards, and how do you think we can learn from what is being discussed beyond Wales and the UK, and have you considered any future legislation to improve water quality?
