Oliver Hides takes your calls on air quality, graves and feeding birds.

A major review of the state of the Welsh environment has warned of "polluted rivers, failing soils" and "collapsing wildlife". Parts of the country also have "some of the worst air quality in Britain" - causing up to 1400 premature deaths a year – that’s all according to Natural Resources Wales. It also comes as there have been growing concerns over what locals describe as a “dreadful” smell from a landfill site near Llanidloes, which has prompted a Senedd petition. Are you concerned about the air quality where you live?

Bereaved families in Carmarthen say they are upset by rules about what can be left on the graves of their loved ones. A newly installed sign at the town's cemetery says candles, balloons, or even photographs are not allowed to be left. Should you be allowed to leave whatever you want at the grave of a loved one?

And do you feed the birds? According to recent estimates, the UK wild bird food market was valued at £380 million - and this was expected to increase. And close to 60% of households feed wild birds. But should we be doing it at all?
